junjie 通过本文主要向大家介绍了centos 安装redis,centos 卸载redis,centos redis,centos 启动redis,centos yum redis等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
用这个脚本管理之前，需要先配置下面的内核参数，否则Redis脚本在重启或停止redis时，将会报错，并且不能自动在停止服务前同步数据到磁盘上：
# vi /etc/sysctl.conf
vm.overcommit_memory = 1
</div>
然后应用生效：
然后增加服务并开机自启动：
# chmod 755 /etc/init.d/redis
# chkconfig –add redis
# chkconfig –level 345 redis on
# chkconfig –list redis
</div>
脚本源码：

# redis - this script starts and stops the redis-server daemon

# chkconfig: - 80 12

注意：请将脚本中redis的启动文件、配置文件和pid文件存放位置按你配置的位置做相应修改，文件保存的时候注意是unix下可运行的模式，否则在linux下运行的时候会提示错误，/bin/bash^M: bad interpreter: No such file or directory
