redis-在乌班图下设置自动启动

一、修改redis.conf

1、打开后台运行选项，默认情况下，Redis不在后台运行；

     daemonize yes 

2、配置log文件地址，默认使用标准输入，即打印在命令行终端 的窗口上

     logfile "/var/log/redis.log"

二、脚本设置

cp /redis的源码目录/utils/redis_init_scripts /etc/init.d/redis 

添加执行权限：chmod +x /etc/init.d/redis 

三、设置开机自动启动，关机自动关闭 

update-rc.d redis  defaults

会提示 insserv: warning: script 'redis6379' missing LSB tags and overrides

则修改脚本，添加前面几行 

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
### BEGIN INIT INFO

        if [ -f $PIDFILE ]

        else

                $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"
        ;;

update-rc.d redis  defaults

尝试启动或停止redis  

service redis start

service redis stop

四、服务检查

 进行常规测试

 如果有错误，可以使用一下命令查看详细信息

 systemctl status redis.service 

 journalctl -xe
