Linux under Memcached Server deployment procedures

Operating system: CentOS 6.x 64-bit

Implementation Purpose: Install deployment memcached Server

First, firewall settings

Vi/etc/sysconfig/iptables #编辑防火墙配置文件, add the following code

-A input-m state--state new-m tcp-p TCP--dport 11211-j ACCEPT

: wq! #保存退出

Service iptables Restart #最后重启防火墙使配置生效

Second, close SELinux

Vi/etc/selinux/config

#SELINUX =enforcing #注释掉

#SELINUXTYPE =targeted #注释掉

Selinux=disabled #增加

: wq! #保存退出

Setenforce 0 #使配置立即生效

Third, the system agreement

Software source code Package storage location:/USR/LOCAL/SRC

Source Package Compile Installation location:/usr/local/software Name

Four, download the software package

1, download libevent

Https://github.com/libevent/libevent/releases/download/release-2.0.22-stable/libevent-2.0.22-stable.tar.gz

2, download memcached

Http://www.memcached.org/files/memcached-1.4.25.tar.gz

Vi. Installation and Configuration memcached

1. Installation Libevent

Cd/usr/local/src

Tar zxvf libevent-2.0.22-stable.tar.gz

CD libevent-2.0.22-stable

./configure--prefix=/usr/local/libevent

Make

Make install

2. Installation memcached

Cd/usr/local/src

Tar zxvf memcached-1.4.25.tar.gz

CD memcached-1.4.25

./configure--prefix=/usr/local/memcached-with-libevent=/usr/local/libevent

Make

Make install

3. Test memcached

Groupadd memcached #创建组

Useradd-g memcached memcached-s/bin/false #创建账号

Ln-s/usr/local/memcached/bin/memcached/usr/local/bin/memcached #添加软连接

The server-side command to start the memcache is:

/usr/local/memcached/bin/memcached-d-M 4096-u root-l 192.168.4.6-p 11211-c 1024-p/usr/local/memcached/memcached.pi D

Or

/usr/local/memcached/bin/memcached-d-M 4096-u memcached-l 192.168.4.6-p 11211-c 1024

Parameter description:

The-D option is to start a daemon,

-M is the amount of memory allocated to Memcache, in megabytes, 4096MB

-U is a user who runs Memcache, such as root or memcached

-L is the IP address of the server that is listening, where the IP address of the server is specified 192.168.4.6 and the default listener server is not set for all IP addresses

-P is the port that sets the Memcache listening by default of 11211

The-c option is the maximum number of concurrent connections to run, by default 1024

-P is set to save the memcache pid file,/usr/local/memcached/memcached.pid

On/etc/rc.d/rc.local, add a line to the boot

/usr/local/memcached/bin/memcached-d-M 4096-u root-l 192.168.4.6-p 11211-c 1024-p/usr/local/memcached/memcached.pi D

You can also use the following command:

/usr/local/memcached/bin/memcached-d-M 4096-p 11211-u memcached

When IP is not specified, the default is to listen for all local IP addresses, and users should choose to be a non-root user, such as memcached

Turn off the memcached service

Cat/usr/local/memcached/memcached.pid #查看进程

Kill 22856 #结束进程

Or

Killall memcached #结束服务
