Centos7 Redis主从搭建配置

一、环境介绍

Redis—master   172.18.8.19
Redis—slave   172.18.8.20

四、redis启动脚本

root># cat /etc/init.d/redis_6379 
#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
# chkconfig:   2345 90 10

source /etc/init.d/functions
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli
 
PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/usr/local/redis/etc/redis_${REDISPORT}.conf"
AUTH="Allwelltokok"
BIND_IP='172.18.8.19'
 
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 does not exist, process is not running"
    else
        PID=$(cat $PIDFILE)
        echo "Stopping ..."
        $CLIEXEC -h $BIND_IP -a $AUTH -p $REDISPORT  SHUTDOWN 
        sleep 1
        while [ -x /proc/${PID} ]
        do
            echo "Waiting for Redis to shutdown ..."
            sleep 1
        done
            echo "Redis stopped"
    fi
}
 
restart(){
    stop
    start
 
}
status(){
 
    ps -ef|grep redis-server|grep -v grep >/dev/null 2>&1
 
    if [ $? -eq 0 ];then
 
        echo "redis server is running"
 
    else
        echo "redis server is stopped"
 
    fi
     
 
}
 
 
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
         
    restart)
        restart
        ;;
         
    status)
        status
        ;;     
    *)
     
     echo "Usage: /etc/init.d/redis {start|stop|status|start}" >&2 
     exit 1 
esac

五、启动服务

root># /etc/init.d/redis_6379 start    

查看日志
