memcache简易安装与配置

一、yum安装：

[root@centos65 /]# yum install memcached -y

 二、参数修改：

内存大小和端口

[root@centos65 /]# vim /etc/init.d/memcached

  内存大小默认64mb

[root@centos65 /]# vim /etc/sysconfig/memcached

 

 

三、多实例memcache

将yum安装好的memcache拷贝一份，重命名

[root@centos65 sysconfig]# cp /etc/init.d/memcached /etc/init.d/memcached11213
[root@centos65 /]# cp /etc/sysconfig/memcached /etc/sysconfig/memcached11213

 

修改新的配置文件，端口和内存大小

[root@centos65 init.d]# vim /etc/init.d/memcached11213

 

对新的memcache11213实例的配置文件进行批量修改

sed -i -e 's#/etc/sysconfig/memcached#/etc/sysconfig/memcached$PORT#g' -e 's#/var/run/memcached/memcached#/var/run/memcached/memcached$PORT#g'  -e 's#/var/lock/subsys/memcached#/var/lock/subsys/memcached$PORT#g' /etc/init.d/memcached11213

启动双实例：

[root@centos65 init.d]# /etc/init.d/memcached start
Starting memcached:                                        [  OK  ]
[root@centos65 init.d]# /etc/init.d/memcached11213 start
Starting memcached:                                        [  OK  ]

 

查看memcache的双实例情况：

[root@centos65 init.d]# netstat -antup | grep memcache
