Centos设置开机启动Redis

网上有很多redis在linux下自动启动的例子，实现的方式很多，很多都是参考一个老外流传出来启动的例子，其实直接使用是不行，而且有很多地方有一些语法错误，这里就讲我实验过，成功的Linux服务chkconfig配置启动的方法。

编写脚本，vim /etc/init.d/redis:

# chkconfig:   2345 90 10
# description:  Redis is a persistent key-value database
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379  #实际环境而定
EXEC=/opt/redis-3.0.4/src/redis-server #实际环境而定
REDIS_CLI=/opt/redis-3.0.4/src/redis-cli #实际环境而定

PIDFILE=/var/run/redis.pid
CONF="/opt/redis-3.0.4/redis.conf" #实际环境而定
#AUTH="1234"

case "$1" in
        start)
                if [ -f $PIDFILE ]
                then
                        echo "$PIDFILE exists, process is already running or crashed."
                else
                        echo "Starting Redis server..."
                        $EXEC $CONF
                fi
                if [ "$?"="0" ]
                then
                        echo "Redis is running..."
                fi
                ;;
        stop)
                if [ ! -f $PIDFILE ]
                then
                        echo "$PIDFILE exists, process is not running."
                else
                        PID=$(cat $PIDFILE)
                        echo "Stopping..."
                       $REDIS_CLI -p $REDISPORT  SHUTDOWN
                       #$REDIS_CLI -p $REDISPORT -a $AUTH  SHUTDOWN

# chkconfig: 2345 10 90
表示通过chkconfig配置，在linux中2、3、4、5项中启动，这个2345代表就linux系统的启动顺序具体，具体内容是：等级0表示：表示关机、等级1表示：单用户模式、等级2表示：无网络连接的多用户命令行模式、等级3表示：有网络连接的多用户命令行模式、等级4表示：不可用、 等级5表示：带图形界面的多用户模式、  等级6表示：重新启动

如果看不明白，自己百度 chkconfig命令详细说明。

AUTH=”1234″
如果redis设置了登录密码，就需要这个配置。

如果找不到pid文件，需要配置redis.conf配置中的选项打开。
修改redis.conf，打开后台运行选项(很多人都会有这种情况，我的也是)：
daemonize yes

添加执行权限：
chmod 755 /etc/init.d/redis

开机自启动：
chkconfig redis on
