centos7-redis启动脚本 根据需要自行修改脚本路径！新建脚本：vim /etc/init.d/redis#!/bin/sh #chkconfig: 2345 80 90 # Simple Redis init.d script conceived to work on Linux systems # as it does use of the /proc filesystem. REDISPORT=6379 EXEC=/usr/local/bin/redis-server CLIEXEC=/usr/local/bin/redis-cli PIDFILE=/var/run/redis_${REDISPORT}.pid CONF="/etc/redis/${REDISPORT}.conf" 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 ;; stop) if [ ! -f $PIDFILE ] then echo "$PIDFILE does not exist, process is not running" else PID=$(cat $PIDFILE) echo "Stopping ..." $CLIEXEC -p $REDISPORT shutdown while [ -x /proc/${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设置开机启动！systemctl daemon-reload systemctl start redis-server.service systemctl enable redis-server.servic
