这篇文章将为大家详细讲解有关 Centos7 下 Redis 主从搭建配置的实现方法，丸趣 TV 小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
一、环境介绍
Redis—master 172.18.8.19

二、redis 主的配置
# 创建 redis 数据目录
mkdir -p /data0/redis_trade

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
root # tail -100f /var/log/redis_6379.log
