| Install eaccelerator

| Eaccelerator is a free and open source PHP accelerator. It optimizes and dynamically caches content, improves the cache performance of PHP scripts, and enables PHP scripts to be compiled, the server overhead is almost completely eliminated. It also optimizes scripts to accelerate execution efficiency. Improves PHP code execution efficiency by 1-10 times

| Eaccelerator caches compiled PHP code to the shared memory and calls the Code directly during user access to accelerate the process efficiently. It is highly efficient, and the process from creating shared memory to searching compiled code is completed in a very short time. For files and code that cannot be cached into the shared memory, the eaccelerator can also cache them to the system disk.

| Eaccelerator only supports PHP installed using mod_php or FastCGI Mode

Wget http://nchc.dl.sourceforge.net/project/eaccelerator/eaccelerator/eAccelerator%200.9.6.1/eaccelerator-0.9.6.1.zip

Unzip eaccelerator-0.9.6.1.zip

/Usr/local/PHP/bin/phpize

./Configure -- prefix =/usr/local/eaccelerator -- enable-eaccelerator = shared -- With-PHP-Config =/usr/local/PHP/bin/PHP-config

Make

Make install

The following prompt is displayed after the installation is successful:

Installing shared extensions:/usr/local/PHP/lib/PHP/extensions/no-debug-non-zts-20060613/

Then, modify the php. ini file:

Vim/usr/local/PHP/etc/PHP. ini

Find extension_dir and add

Extension = "eaccelerator. So"

Configure eaccelerator to accelerate PHP:

[Eaccelerator]

Zend_extension = "/usr/local/PHP/lib/PHP/extensions/no-debug-non-zts-20060613/eaccelerator. So"

Eaccelerator. shm_size = "16" # shared memory settings, in MB. The default value is 0.

Eaccelerator. cache_dir = "/tmp/eaccelerator" # cache directory

Eaccelerator. Enable = "1" # enable or disable eaccelerator, 1 = on, 0 = off; default value: 1

Eaccelerator. optimizer = "1" # enable or disable the internal optimizer. The default value is 1.

Eaccelerator. check_mtime = "1" # Start or close the PHP file modification check. The default value is 1.

Eaccelerator. DEBUG = "0" # enable or disable high Logging

Eaccelerator. Filter = "" # determine which PHP files must be cached. You can specify the cached and non-cached file types (for example, "*. php *. phtml"). If the parameter is set "! ", Files matching these parameters are ignored. The default value is ""; that is, all PHP files will be cached.

Eaccelerator. shm_max = "0" # when using the "eaccelerator_put ()" function, it is prohibited to store excessive files in the shared memory. This parameter specifies the maximum value that can be stored, in bytes (10240, 10 K, 1 m ). "0" is unlimited. The default value is "0 ".

Eaccelerator. shm_ttl = "0" # When the eaccelerator fails to obtain the shared memory size of the new script, it will delete all script caches that have not been accessed in the last "shm_ttl" seconds from the shared memory. The default value is "0". That is, no cached files are deleted from the shared files in the spring.

Eaccelerator. prune_period = "0" # When eaccelerator fails to obtain the shared memory size of the new script, it will try to delete the cache script earlier than "shm_prune_period" from the shared memory. The default value is "0". That is, no cached files are deleted from the shared files in the spring.

Eaccelerator. shm_only = "0" # Allow or disable caching compiled scripts on disks. This option is invalid for session data and content caching. The default value is "0", that is, cache with disk and shared memory.

Eaccelerator. Compress = "1" # Allow or disable content caching. The default value is "1", that is, compression is allowed.

Eaccelerator. compress_level = "9" # specify the compression level of the content cache. The default value is 9, which is the highest level.

Eaccelerator. Keys = "disk_only"

Eaccelerator. Session = "disk_only"

Eaccelerator. content = "disk_only"

### Set the content cache storage location:

Shm_and_disk in shared cache and hard disk (default)

SHM has shared memory by default. If the shared memory is full or the size exceeds the value of "eaccelerator. shm_max", it is saved to the hard disk.

Shm_only is stored only in the shared memory.

Disk_only is stored on the hard disk

None

 

Eaccelerator. allowed_admin_path = "/var/www/html/21andy.com/eaccelerator"

### This is a control in the control panel address installation package. PHP: You can copy it to any directory on the website and use it to view and manage it. This must be specified. Otherwise, an error occurs when you view the cached content.

 

| Configure PHP-FPM

Nginx + PhP requires PHP to generate executable files. Therefore, FastCGI technology should be used to integrate nginx with PHP. This is as long as FastCGI is enabled for installation. here, we use PHP-FPM to manage FastCGI (PHP-FPM has been added to PhP as a patch ).

Edit the configuration file:

Vim php-fpm.conf.

About 63 rows. Remove the corresponding comments and specify the user for FastCGI. You can use the default nobody or specify it separately.

 

UNIX user of processes

<Value name = "user"> nobody </value>

 

UNIX group of processes

<Value name = "group"> nobody </value>

| Smoothly change the nginx configuration without stopping the nginx Service

After modifying the configuration file nginx. conf, run the following command to check whether the configuration file is correct:

/Usr/local/nginx/sbin/nginx-T

If the following message is displayed, the modification is successful:

 

Nginx: the configuration file/usr/local/nginx/CONF/nginx. conf syntax is OK

Nginx: configuration file/usr/local/nginx/CONF/nginx. conf test is successful

 

 

Run the following command to view the nginx master process number:

PS aux | grep "nginx: Master process" | grep-V "grep" | awk '{print $2 }'

Or

CAT/usr/local/nginx/logs/nginx. PID

After finding the main process number, run the following command to make the configuration file take effect:

Kill-HUP master process number

Or

Kill-HUP 'ps aux | grep "nginx: Master process" | grep-V "grep" | awk '{print $2 }''

Kill-HUP 'cat/usr/local/nginx/logs/nginx. pid'

 

############

The acceptable signals of nginx are as follows:

Term, int terminate the server immediately
Quit stop the server
Hup configuration changes, start new workers, graceful stop of old workers
Usr1 reopen log files
Usr2 upgrade the server executable
Winch graceful stop (parent process advise the children to Exit)
Kill-hup pid re-apply the configuration file
Kill-usr1 PID refresh log
