Operating system: CentOS 6.x 64-bit

Implementation purpose: Install and deploy the 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, to 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 contract

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

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

Iv. Download the 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

V. Install the build Kit

Yum install-y apr* autoconf automake bison cloog-ppl compat* cpp Curl curl-devel fontconfig fontconfig-devel freetype fre etype* freetype-devel gcc gcc-c++ gtk+-devel gd gettext gettext-devel glibc kernel kernel-headers keyutils keyutils-libs-d Evel Krb5-devel libcom_err-devel libpng* libjpeg* libsepol-devel libselinux-devel libstdc++-devel libtool* Libgomp LIBXML2 libxml2-devel libxpm* libtiff libtiff* libx* make MPFR ncurses* ntp OpenSSL openssl-devel patch pcre-devel perl ph P-common php-gd policycoreutils ppl telnet t1lib t1lib* nasm nasm* wget zlib-devel gmp-devel

VI. Installation 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 commands to start the memcache are:

/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 running memcache, such as root or memcached

-L is the server IP address of the listener, here specifies the IP address of the server 192.168.4.6, does not set the default listening server all IP addresses

-P is the port that sets Memcache listening, which defaults to 11211

The-c option is the maximum number of concurrent connections that are running, by default 1024

-P is a PID file that is set to save Memcache,/usr/local/memcached/memcached.pid

Start-up, add a line to the/etc/rc.d/rc.local

/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

IP is not specified, the default listener local all IP address, the user is best to choose non-root users, such as memcached

Close 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

4, set memcached boot

Vi/etc/rc.d/init.d/memcached

#!/bin/sh

#

#

# Chkconfig:-90 25

At this point, the Linux memcached Server deployment is complete.
