redis集群设置开启自启动

操作环境

服务器centos7.3, ip:47.52.41.245，所包含的集群节点有7003,7004,7005

开启防火墙

systemctl eable firewalld.service 

redis集群设置开启自启动

这里是设置的是集群里面某个redis节点开机启动，没有使用集群，这里设置的是7003服务

1. 根据启动脚本要求，将某个节点的配置文件以端口为名复制一份到指定目录，这里复制到/etc/redis_cluster

cd /etc
mkdir redis_cluster
cd redis_cluster
cp /tmp/frank/redis/redis-3.2.1/redis_cluster/* /etc/redis_cluster/

2. 在/etc/init.d目录下面新建启动脚本并且命名为redis7003

vim redis7003

完整配置信息为

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /pro filesystem.
# chkconfig:2345 90 10
# description:Redis is a persistent key-value database

REDISPORT=7003
EXEC=/tmp/frank/redis/redis-3.2.1/src/redis-server
CLIEXEC=/tmp/frank/redis/redis-3.2.1/src/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/etc/redis_cluster/${REDISPORT}/redis.conf"

case "$1" in
   start)
   if [ -f $PIDFILE ]
   then
       echo "$PIDFILE exists,process is already running or crashed"
   else
       echo "Starting Redis server $REDISPORT ..."
       $EXEC $CONF
   fi  
   ;;
   stop)
   if [ ! -f $PIDFILE ]
   then
       echo "$PIDFILE does not exit,process is not running"
   else
       PID=$(cat $PIDFILE)
       echo "Stopping"
       $CLIEXEC -p $REDISPORT shutdow
       while [ -x /proc/${PID}]
       do
           echo "Waiting for Redis to shutdown ..."
           sleep 1
       done
       echo "Redis stopped"
   fi
   ;;
   *)
   echo "Please use start or stop as first argument"
   ;;
esac

3. 修改启动文件的权限

chmod +x /etc/init.d/redis7003

4. 设定开机启动服务

chkconfig redis7003 on  

5. 启动,停止redis

service redis start   #或者 /etc/init.d/redis start  
service redis stop   #或者 /etc/init.d/redis stop

6. reboot重启服务器

7. 测试服务是否启动

[root@iZj6c7eeosj2t5vjw8rf4xZ init.d]# redis-cli -c -p 7003
127.0.0.1:7003> 

8.其余节点按上面步骤继续
