redis默认安装查看+开机自启动

linux查看服务器安装目录redis

如果用命令 which redis 或者 whereis redis 都找不到安装目录，

可使用以下办法:

ps -aux|grep redis 

ps -ef|grep redis

假如得到了进程号 16678然后用命令

ll /proc/16678/cwd

redis开机自启动

1.编写脚本

[root@localhost ~]# vi /etc/init.d/redis

2.复制下面代码到脚本中(注意要修改里面redis的安装路径,以/usr/redis/redis-3.2.4路径为例)(这段代码就是redis根目录 /utils/redis_init_script 启动脚本的代码)

#!/bin/sh
# chkconfig: 2345 10 90  
# description: Start and Stop redis   

REDISPORT=6379
EXEC=/usr/redis/redis-3.2.4/src/redis-server
CLIEXEC=/usr/redis/redis-3.2.4/src/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/usr/redis/redis-3.2.4/redis.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
        ;;
    restart)
        "$0" stop
        sleep 3
        "$0" start
        ;;
    *)
        echo "Please use start or stop or restart as first argument"
        ;;
esac

3.保存退出,设置权限

[root@localhost ~]# chmod 777 /etc/init.d/redis

4.设置开机自启动:

chkconfig --add redis #添加redis服务
chkconfig redis on

5.重启reboot

[root@localhost ~]# service redis start
