The Perfect APC Configuration

2013-03-26T09:36:40Z

I’m hosting about 10 ExpressionEngine sites using Apache 2, APC, and Memcached. Here is my configuration:

Operating system - Mac OS X Server Lion 10.7.5 (11G63)
Processor - 2 GHz Intel Core i7
RAM - 16 GB 1333 MHz DDR3
Disk - 13.5 TB total
Apache - 2.2.22
PHP - 5.3.15
APC - 3.1.13

My php.ini configuration

[APC]
apc.enabled=1
apc.shm_segments=1

;51M per ExpressionEngine install
apc.shm_size=512M

;Relative to the number of cached files (you may need to watch your stats for a day or two to find out a good number)
apc.num_files_hint=7000

;Relative to the size of ExpressionEngine
apc.user_entries_hint=4096

;The number of seconds a cache entry is allowed to idle in a slot before APC dumps the cache
apc.ttl=7200
apc.user_ttl=7200
apc.gc_ttl=3600

;Setting this to 0 will give you the best performance, as APC will
;not have to check the IO for changes. However, you must clear
;the APC cache to recompile already cached files. If you are still
;developing, set this to 1
apc.stat=0

;This MUST be 0, ExpressionEngine can have errors otherwise!
apc.include_once_override=0

;Only set to 1 while debugging
apc.enable_cli=0

;Allow 2 seconds after a file is created before it is cached to prevent users from seeing half-written/weird pages
apc.file_update_protection=2

;Leave at 2M or lower. ExpressionEngine does't have any file sizes close to 2M
apc.max_file_size=2M

apc.cache_by_default=1
apc.use_request_time=1
apc.slam_defense=0
apc.mmap_file_mask=/tmp/apc.XXXXXX
apc.stat_ctime=0
apc.canonicalize=1
apc.write_lock=1
apc.report_autofilter=0
apc.rfc1867=0
apc.rfc1867_prefix =upload_
apc.rfc1867_name=APC_UPLOAD_PROGRESS
apc.rfc1867_freq=0
apc.rfc1867_ttl=3600
apc.lazy_classes=0
apc.lazy_functions=0

While this configuration works great for me, it may not for you. Finding “The Perfect APC Configuration” is like asking how many stars are in the sky. The are endless variables, like, “How much RAM, how many websites, do your websites support lazy classes, etc…” The best way to create your config is to do a little research.

P.S. There seems to be a lot of debate about apc.stat = 0. The general thought is, set apc.stat=0 on production servers and it will prevent APC from actually going to the IO to check if the file has been changed.

My advice: If you are running ExpressionEngine set apc.stat = 0.

It’s official, II

2012-07-23T11:15:33Z

It’s official, today 4 years ago we changed our name and launched our current website.

To celebrate our birthday:

Coming up:

Major CMS upgrade

2012-02-09T18:35:00Z

Expressionengine 1.7.1 -> 2.4 Major upgrade
- We needed to upgrade for future grow, more on this soon.
- New version is faster and more secure.
- and a lot more....

Installed AutoMin (an EE module)

MacMini Server 2011 Part I

2012-01-05T13:54:07Z

Part I: Intro and Goal.
Part II: Preparations.
Part III: Installation.
Part IV: Settings.

Intro:
My G5, dual 2Ghz and 8GB ram, server was still working like a charm.
(Including a G5 Jive to add 4 extra Internal Sata disks - total 6 Internal Disks)

But the downside:
- Heat, lots of heat. I even placed an airco in my server room.
- Costs, A PowerMac G5 uses max 604 Watt. Add the airco time and your monthly bill will increase rapidly.
- Noise, Due to the major fans, the heats it generates. I (sound)isolated the server room.

Goal:
My own new web/mail/file/media server that generates less noise, heat and uses less power. And the right storage solution.

Solution:
MacMini Server 2011 (2Ghz i7 Quad-core, 2 x 750 GB HD @ 7200 and 16GB RAM)
MacMini uses: 8W (Idle) 18W (regular use) 85W (max)
Sound: Silent (no sound)

MacMini server: English - Dutch
2 X 8 GB ram: English - Dutch

Empty Enclosure for my 4 extra Internal HD's (JBOD)
OWC RackPro Uses: 16W (Idle) 24W (regular use) 100W (max)
Sound: Silent (no sound)

Thunderbolt to eSata: Thunderbolt Adapter and eSATA adapter
(two eSata connectors for future grow)

Why eSata and not USB3:
USB3 is theoretically faster but eSata has no latency what makes it high responsible and low/none system resource use.

MacMini Server 2011 Part II

2012-01-05T13:45:13Z

Part II: Preparations.

Full web server, mailserver, caldav and carddav with webmin/virtualmin.

Update OS X 10.7 server software.
Download Xcode 4.1 + install
Download ServerAdminTools + install
Download Java + install
Download java developer + install
Repair permissions

Xcode 4.2 discontinued GCC 4.2 compiler and downgraded LLVM-GCC to 'legacy' compiler.
Meaning that a lot of scripts/programs will not compile right until they are updated.
This is the reason I stayed with Xcode 4.1. If you encounter problems please downgrade your Xcode 4.2.x to 4.1. (if you relay on my ffmpeg bash script you need to use Xcode 4.1)

Preps:
- While push mail didn't work for my setup, I decided to not use it.
- But also when push was enabled, using my mac email account, I was not able to send a mail to my mac email account from the server. It continues to get back. (loop)
- After installation, at the server setup section. Do not enter your mac account.

Set computer name: server
Set NS name: server.yourdomain.com

Enable Root:
Macintosh HD -> System -> Library -> CoreServices -> Directory Utility
Menu -> edit -> enable Root
Enter a new password 2 times.
Root enabled

Dedicate system resources:
Start the server.app
Select your computer under hardware.
Press on settings. (see image)
Disable "Dedicate system resources to server services"
Restart your server.

MacMini Server 2011 Part III

2012-01-05T13:37:47Z

Part III: Installation.

We are going to use brew to install several libs and programs.
Big advantage of brew is that it makes simlinks into the local bin, lib and sbin folders.
No mess as macports or fink (let's say I like this way better.)

======= Brew =======
Brew will ask to add and change some path info. You may do this by editing
BBEdit:

open /etc/paths
/usr/local/sbin (infront of /usr/sbin/)
/usr/local/bin (infront of /usr/bin/)

Terminal:

mkdir /usr/local/Cellar

/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

Only in case there is an error.

chown name:admin /usr/local/share
chown name:admin /usr/local/share/man
chown name:admin /usr/local/share/man/man1
chown name:admin /usr/local/Cellar

Terminal:
brew update

brew install GD
brew install wget
brew install apc
brew install libtiff
brew install ghostscript
brew install imagemagick
brew install logrotate
brew install mcrypt
brew install qdbm
brew install memcached
brew install memcache-php
brew install memcache-top
brew install lynx
brew install smartmontools
brew install libconfig
brew install GnuPG
brew install re2c

Some extra brews I could use.

brew install xmlrpc-c
brew install xml-coreutils
brew install webfs
brew install webkit2png

Read my notes.

brew install ffmpeg *
brew install ffmpeg-php *
brew install rrdtool **
brew install ruby **
brew install lsof **
brew install snort **
brew install libxml2 **
brew install cairo **
brew install squid ****
brew install webalizer ***
brew install mysql *****

* don't use brew for this, I wrote a script that will install it all for you, and this one works
** only needed if you would like to install system stats in webmin.
*** do not install trough brew, berkery DB will cause some problems later on. (example squid or when you want to run your own postfix version)
**** only needed if you would like to run squid proxy.
***** Or follow the steps below (recommended)

======= Create a work folder =======
We are going to download some software that we need to compile. The most clean way is to create a folder where we will put all the files.
My case "work" on your main HD.

mkdir /work

======= Installing FFMPEG and FFMPEG-php =======
Download my script into the work folder.
Open terminal and su root.

cd /work
wget http://www.4elements.com/files/macmini_server/ffmpegphp_ok.sh.zip
unzip ffmpegphp_ok.sh.zip
bash ffmpegphp_ok.sh

This will take a while.

======= Installing MYSQL =======
Download MYSQL: http://dev.mysql.com/downloads/mysql/
Pick the "Mac OS X ver 10.6 (x86, 64-bit), DMG" mysql-5.5.16-osx10.6-x86_64.dmg

Turn mysql on. (system prefs)

sudo mkdir /var/mysql
sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock

ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql
ln -s /usr/local/mysql/bin/mysqld /usr/libexec/mysqld

Add to /etc/paths

/usr/local/mysql/bin"

sudo install_name_tool -id /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.dylib

Set up MySQL root password: (without the {})

/usr/local/mysql/bin/mysqladmin -u root password {password}
/usr/local/mysql/bin/mysqladmin -u root -p{password} -h localhost password {password}
/usr/local/mysql/bin/mysqladmin -u root -p{password} reload

======= Installing CPAN =======
Su root
cpan (OSX 10.7 has 64bit as default, all will be installed as 64bit)

ftp.domainname.com. IN A xx.xx.xx.xx
ns01.domainname.com. 14400 IN A xx.xx.xx.xx
ns02.domainname.com. 14400 IN A xx.xx.xx.xx
domainname.com. 86400 IN NS ns01.domainname.com.
domainname.com. 86400 IN NS ns02.domainname.com.
domainname.com. IN MX 10 mail.domainname.com.

Now goto your domain rigistar and add at the dns section
ns01.yourdomain.com - IP address here
ns02.yourdomain.com - IP address here
it can take upto 24 hours before it's progressed.
(depending on the domain rigistar you use)

======== PRO FTP ========
webmin -> Un-used Modules -> proftp -> module config

ProFTP:
Path to ProFTPD config file: /usr/local/proftpd/etc/proftpd.conf
Path to ProFTPD executable: /usr/local/proftpd/sbin/proftpd
Path to ProFTPD PID file:/usr/local/proftpd/var/proftpd.pid
Path to ftpusers file None (was /etc/ftpusers)

Before we can start ProFTPD, we need to make some OS X specific adjustments. Go ahead and open up the "ProFTPD Server" module under the "Servers" section. Select the "Edit Config Files" option. Look for the line that has the comment "Set the user and group under which the server will run." and comment out the next two lines so it looks like this:

# Set the user and group under which the server will run.
#User nobody
#Group nogroup
Click the "Save" button to return to the main menu. By now you should have a functional FTP server. However, thier are a couple of "tweaks" I like to do to make things work a little better. Lets start by removing the login delay.

Click on "Networking Options" in the ProFTPD module's main menu.
Change the "Do reverse DNS lookups of client" option to "No".
Change the "Lookup remote ident username" option to "No".
PASV port range: 60000 - 65535
Click "Save" to save and return to the main menu.

Lets allow the use of "CHMOD":
In the main menu, under "Virtual Servers" click "Default server".
Under "Per-directory and Per-command options" click "Commands SITE_CHMOD".
Click "Access Control".
Change the "Access Control Policy" option to "Allow all clients".
Click "SITE_CHMOD".
set FTP commands to All (or just what you like)

Click "Save" to save. Then click "return to main menu".

Limit Users to Home Directory:
Click on "Files and Directoriess" in the main menu.
Change the "Limit users to directories" option to "Home Directory".
Click "Save" to save and return to the main menu".

To avoid hack attacks, change the port number of proftp.
I changed it from port 21 to XXXX (pick your own number)
I also disabled anonymous ftp.

SSL Options: Generate a .crt and .key file

Step 1: Generate a Private Key

The openssl toolkit is used to generate an RSA Private Key and CSR (Certificate Signing Request). It can also be used to generate self-signed certificates which can be used for testing purposes or internal usage.

The first step is to create your RSA Private Key. This key is a 1024 bit RSA key which is encrypted using Triple-DES and stored in a PEM format so that it is readable as ASCII text.

openssl genrsa -des3 -out server.key 1024

Generating RSA private key, 1024 bit long modulus
.........................................................++++++
........++++++
e is 65537 (0x10001)
Enter PEM pass phrase:
Verifying password - Enter PEM pass phrase:

Step 2: Generate a CSR (Certificate Signing Request)

Once the private key is generated a Certificate Signing Request can be generated. The CSR is then used in one of two ways. Ideally, the CSR will be sent to a Certificate Authority, such as Thawte or Verisign who will verify the identity of the requestor and issue a signed certificate. The second option is to self-sign the CSR, which will be demonstrated in the next section.

During the generation of the CSR, you will be prompted for several pieces of information. These are the X.509 attributes of the certificate. One of the prompts will be for "Common Name (e.g., YOUR name)". It is important that this field be filled in with the fully qualified domain name of the server to be protected by SSL. If the website to be protected will be https://public.akadia.com, then enter public.akadia.com at this prompt. The command to generate the CSR is as follows:

openssl req -new -key server.key -out server.csr

Country Name (2 letter code) [GB]:CH
State or Province Name (full name) [Berkshire]:Bern
Locality Name (eg, city) [Newbury]:Oberdiessbach
Organization Name (eg, company) [My Company Ltd]:Akadia AG
Organizational Unit Name (eg, section) []:Information Technology
Common Name (eg, your name or your server's hostname) []:public.akadia.com
Email Address []:martin dot zahn at akadia dot ch
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

Step 3: Remove Passphrase from Key

One unfortunate side-effect of the pass-phrased private key is that Apache will ask for the pass-phrase each time the web server is started. Obviously this is not necessarily convenient as someone will not always be around to type in the pass-phrase, such as after a reboot or crash. mod_ssl includes the ability to use an external program in place of the built-in pass-phrase dialog, however, this is not necessarily the most secure option either. It is possible to remove the Triple-DES encryption from the key, thereby no longer needing to type in a pass-phrase. If the private key is no longer encrypted, it is critical that this file only be readable by the root user! If your system is ever compromised and a third party obtains your unencrypted private key, the corresponding certificate will need to be revoked. With that being said, use the following command to remove the pass-phrase from the key:

cp server.key server.key.org
openssl rsa -in server.key.org -out server.key

The newly created server.key file has no more passphrase in it.

-rw-r--r-- 1 root root 745 Jun 29 12:19 server.csr
-rw-r--r-- 1 root root 891 Jun 29 13:22 server.key
-rw-r--r-- 1 root root 963 Jun 29 13:22 server.key.org

Step 4: Generating a Self-Signed Certificate

At this point you will need to generate a self-signed certificate because you either don't plan on having your certificate signed by a CA, or you wish to test your new SSL implementation while the CA is signing your certificate. This temporary certificate will generate an error in the client browser to the effect that the signing certificate authority is unknown and not trusted.

To generate a temporary certificate which is good for 365 days, issue the following command:

openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
Signature ok
subject=/C=CH/ST=Bern/L=Oberdiessbach/O=Akadia AG/OU=Information
Technology/CN=public.akadia.com/Email=martin dot zahn at akadia dot ch
Getting Private key

Step 5: Installing the Private Key and Certificate

When Apache with mod_ssl is installed, it creates several directories in the Apache config directory. The location of this directory will differ depending on how Apache was compiled.

cp server.crt /usr/local/apache/conf/ssl.crt
cp server.key /usr/local/apache/conf/ssl.key

Step 6: Configuring SSL Enabled Virtual Hosts

SSLEngine on
SSLCertificateFile /usr/local/apache/conf/ssl.crt/server.crt
SSLCertificateKeyFile /usr/local/apache/conf/ssl.key/server.key
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
CustomLog logs/ssl_request_log \
"%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

Step 7: Restart Apache and Test

apachectl stop
apachectl start

There are 2 ways to setup apache. I choose to use the default settings of apache to work well with webmin.

Specific setup for use with server.app is easy accomplish.
Both instruction will be posted on a later stage.

======== Mail server ========

A complete solution will be provided. Stay tuned.
(Below is the raw version, for those who requested.)

======== Dovecot IMAP/POP3 Server ========
We will configure the mail our selves, but to get all config files created
please launge "Admin Server" add mail and start the mail server. This will generate all files we need. (stop the mail server when generation is done)

Dovecot server program: /usr/sbin/dovecotd
Full path to Dovecot configuration file: /etc/dovecot/dovecot.conf
Dovecot server PID file: /var/run/dovecot/master.pid

Mail Files:
Mail file location: Inbox and folders in ~/Maildir
UIDL format: %08Xu%08Xv

======== Postfix Mail Server ========
The message "group or other writable" means that another user (not the owner) is able to write. You can fix it with chmod. Example to remove group write permissions

$ sudo chmod g-w /Library/Server/Mail/Data/mta

Suggest to create a backup of /etc/postfix /etc/dovecot and /etc/apache2
cd /etc
/Developer/Tools/CpMac -r apache2 "apache2 backup"
/Developer/Tools/CpMac -r postfix "postfix backup"
/Developer/Tools/CpMac -r dovecot "dovecot backup"

While it's possible to write all steps by hand, I decided to attach the config files.
(change my files and copy them to the ment folders. i'll explain during the process)

Memcache vs APC cache in PHP

2011-07-19T07:53:04Z

I often see this question asked; which is a better caching mechanism for PHP: Memcache or APC cache. I wanted to write about how different both of them are inherently in their very concept.

Memcache for PHP is a distributed caching mechanism. If you have several webservers running under a load balancer serving the same content and you want a caching mechanism to avoid frequent database hits , Memcache is the way to go. When using Memcache you will make the update to one webserver and it would be auto-replicated across all the severs through distributed caching mechanism. Since it requires dealing with network protocols in order to support the distributed part of caching, it is slower compared to APC cache. If data is stored in APC cache, updates need to be done individually on all APC caches on all web servers. They wont be automatically replicated.

However, Memcached is NOT an Opcode cacher like APC. APC when employed will cache all the opcode the first time it is converted and serve the cached version for subsequent HTTP requests. APC can also be used to store data like Memcache but in a non-distributed manner. Most of the times memcache is used to store results of time consuming data queries, so the need to hit database on every query is eliminated and this gives a huge performance benefit.

The good part of both these technologies, is that they are compatible with each other. A good design for scalable websites should be employing APC for opcode caching and data-caching through Memcache to exploit the distributed capabilities across several webservers. If there is just a single webserver, using just APC cache for both opcode and data caching is a good idea.
