Install memcache and memcached_PHP tutorial

Simply put

Memcache is the name of the general cache system project, which is easily confused with memcache in the PHP tutorial.

We often mention that memcache is actually memcache in php, which is the memcached extension support of php.

We often mention that memcached is the main program file of the server and the installation program of the server.

In order to make your program fly, you must install the memcached server program and the memcached extension of php, so if you want to use memcache to cache the system, we need to install both memcache and memcached.

Install memcache

# cd /usr/local/src
# wget http://pecl.php.net/get/memcache-2.2.5.tgz
# gzip -d memcache-2.2.5.tgz
# tar xvf memcache-2.2.5.tar
# cd memcache-2.2.5

The following sentences refer to the directory where php is located as / usr/local/php as an example. If your php has changed, please replace the part of /usr/local/php in the sentences

# /usr/local/php/bin/phpize
# ./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config --with-zlib-dir
# make && make install

will memcache added php extension

# vi /etc/php.ini (/etc/php.ini address is the location of my php.ini. If you don’t know where your php.ini is, you can use # find / -name php.ini to search, or pass a probe phpinfo to find the location of php.ini in the configuration file (php.ini) path).

Install memcached below

To install memcached, you first need to install libevent

If it is centos, you can install it with yum

# yum install libevent-devel

If the system does not support yum, you can install libevent like this

# cd / usr/local/src
# wget http://www.monkey.org/~provos/libevent-1.4.12-stable.tar.gz
# tar vxf libevent-1.4.12-stable.tar. gz
# cd libevent-1.4.12
# ./configure --prefix=/usr/local/libevent
# make && make install

Continue to install memcached

# cd /usr/local/src
# wget http://cloud.github.com/downloads/saberma/saberma.github.com/memcached-1.4.4.tar.gz
# tar vxf memcached -1.4.4.tar.gz
# cd memcached-1.4.4
# ./configure --prefix=/usr/local/memcached
# make && make install

Installation After completion, start memcached and allocate 32m of memory (32 is the number of used memory, which can be modified according to your own situation)

/usr/local/memcached/bin/memcached -d -m 32 -l 127.0.0.1 -p 11211 -u root

Add memcached to startup items

# vi /etc/rc.d/rc.local

Press i on the keyboard to start editing

Add

/usr/local/memcached/bin/memcached -d -m 32 -l 127.0.0.1 -p 11211 -u root at the end

Press the esc key and enter

：wq

Save and exit

If necessary, you can reboot, but it should have taken effect without reboot~
