Preliminary Study on memcache (1) -- install memcached in centos

Your website may encounter access bottlenecks. How to solve this problem has always been a dark cloud on the project team.

Because I have no experience in creating too many websites, I collected a lot of information on the Internet, so I learned about memcached and its application.

 

I. Prepare the compilation environment

Bytes ---------------------------------------------------------------------------------------------------------

Yum install gcc
Yum install gcc-C ++ libstdc ++-devel
Yum install zlib-devel

Bytes ---------------------------------------------------------------------------------------------------------

Ii. source code package preparation
The server is mainly installed on the memcache server, the latest version is memcached-v1.4.13.
Wget http://memcached.googlecode.com/files/memcached-1.4.13.tar.gz

In addition, memcache uses the libevent library for socket processing, so you also need to install libevent
Wget
Https://github.com/downloads/libevent/libevent/libevent-2.0.17-stable.tar.gz -- no-check-Certificate

Prepare the memcached PHP extension source code installation package:
Wget http://pecl.php.net/get/memcache-3.0.6.tgz

 

Iii. installation and configuration

1. Compile and install libevent
./Configure -- prefix =/usr
Make & make install

Test whether the libevent is successfully installed:
Ls-Al/usr/lib | grep libevent

2. Install memcached and specify the libevent installation location during installation.
./Configure -- With-libevent =/usr
Make & make install

Test whether memcached is successfully installed:
Ls-Al/usr/local/bin/MEM *

 

3. Enable the memcached daemon

Memcached-D-u Root

Bytes ---------------------------------------------------------------------------------------------------------

# Connection Parameters

-P listening port

-L connected IP address. The default value is local

-D start: Start the memecache service.

-D restart

-D stop | Shutdown

-D install

-D uninstall

-U is only valid for running as root

-M maximum memory usage, unit MB, default 64 MB, maximum 2G

-An error is returned when M memory is exhausted.

-C maximum number of simultaneous connections. The default value is 1024.

-The F block size increases because the default value is 1.25.

-N: minimum space allocated. The default value is key + value + flags.

-H Show Help

 

4. Use telnet to test whether the installation is successful

Bytes ---------------------------------------------------------------------------------------------------------
Telnet local host 11211

# A client error occurs when you press Enter.
Quit # exit

Bytes ---------------------------------------------------------------------------------------------------------

 

Iv. php extension Installation

1. Compile and install libmemcached
Bytes ---------------------------------------------------------------------------------------------------------

./Configure -- prefix =/usr/local/libmemcached

Make & make install

Bytes ---------------------------------------------------------------------------------------------------------

2. Find the phpize directory.

Bytes ---------------------------------------------------------------------------------------------------------
Find/-name phpize

Bytes ---------------------------------------------------------------------------------------------------------
Enter the value based on the returned value. In centos, it is generally/usr/bin/phpize.

3. install PHP-memcache

Bytes ---------------------------------------------------------------------------------------------------------

/Usr/bin/phpize

./Configure -- enable-memcache -- With-PHP-Config =/usr/bin/PHP-config -- prefix =/usr/local/memcached -- With-zlib-Dir

#. /Configure -- With-PHP-Config =/usr/bin/PHP-config -- prefix =/usr/local/memcached -- With-libmemcached-Dir =/usr/local/libmemcached

Make & make install

Bytes ---------------------------------------------------------------------------------------------------------
After the installation is complete, the following message is displayed:
Installing shared extensions:/usr/lib/PHP/modules/

4. Modify the PHP configuration

Modify extension_dir = "./" in PHP. ini

Bytes ---------------------------------------------------------------------------------------------------------
Extension_dir = "/usr/lib/PHP/extensions/no-debug-non-zts-2007xxxx /"

Extension = memcached. So

Bytes ---------------------------------------------------------------------------------------------------------

 

5. Some instructions

The following warning message may exist during installation:

Bytes ---------------------------------------------------------------------------------------------------------
# Configure: Warning: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers.
Wget

Http://sourceforge.net/projects/re2c/files/re2c/0.13.5/re2c-0.13.5.tar.gz/download

Tar-zxvf re2c-0.13.5.tar.gz
CD re2c-0.13.5
./Configure & make install
