1. Install Xcache

The Code is as follows:

# Wget
# Tar zxvf xcache-1.3.0.tar.gz
# Cd xcache-1.3.0
#/Usr/local/php/bin/phpize
#./Configure -- enable-xcache-coverager -- enable-xcache-optimizer -- with-php-config =/usr/local/php/bin/php-config
# Make & make install

Note:
-- Enable-xcache indicates that Xcache support is enabled;
-- Enable-xcache-coverager indicates additional features used to measure accelerator efficacy;
-- Enable-xcache-optimizer indicates that the operation code optimization is enabled.

After the installation is complete, the system prompts xcache. so module generated path, this generated path for/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/, and then xcache. so move to the/usr/local/php/include/php/ext directory.
Ii. configure and manage Xcache
1. Modify the php configuration file
During configuration, we can refer to the xcache configuration template xcache. ini, which is located in the Xcache installer.
# Vi/usr/local/php/lib/php. ini
Then add the following content:

The Code is as follows:

Extension_dir =/usr/local/php/include/php/ext
[Xcache-common]
Extension = xcache. so

[Xcache. admin]

Xcache. admin. enable_auth = On
Xcache. admin. user = "xcache"
Xcache. admin. pass = ""

[Xcache]
Xcache. shm_scheme = "mmap"
Xcache. size = 60 M
Xcache. count = 1
Xcache. slots = 8 K
Xcache. ttl = 0
Xcache. gc_interval = 0
Xcache. var_size = 4 M
Xcache. var_count = 1
Xcache. var_slots = 8 K
Xcache. var_ttl = 0
Xcache. var_maxttl = 0
Xcache. var_gc_interval = 300
Xcache. test = Off
Xcache. readonly_protection = On
Xcache. mmap_path = "/tmp/xcache"
Xcache. coredump_directory = ""
Xcache. cacher = On
Xcache. stat = On
Xcache. optimizer = Off

[Xcache. coverager]
Xcache. coverager = On
Xcache. coveragedump_directory = ""

2. Generate Xcache cache files
# Touch/tmp/xcache
# Chmod 777/tmp/xcache

3. Generate the Xcache administrator secret (MD5 ciphertext)
# Echo-n" 123456 "| md5sum
E10adc3949ba59abbe56e057f20f883e
Then paste the generated MD5 ciphertext into the php. ini file xcache. admin. pass = "" option, U.S. server, xcache. admin. pass = "e10adc3949ba59abbe56e057f20f883e"

4. Copy the Xcache hypervisor to the root directory of the website.

The Code is as follows:

# Cp-a/tmp/xcache-1.3.0/admin // usr/local/nginx/html/

Then restart PHP and access it. The user name is xcache and the password is 123456. In addition, you can use phpinfo to verify whether PHP supports Xcache.
