Redis的多种启动方式比较！

有感：

Redis玩了许久时间，真心感觉启动方式还是自己定义的方便！

1）直接启动和关闭：（配置文件默认）

开启：redis-server &（&后台运行）

#daemonize yes（也可配置文件修改此参数）

关闭：redis-cli shutdown or killall -9 redis-server

2）指定配置文件启动：

redis-server /etc/redis.conf(配置文件可自己定义)

如果更改了redis默认端口：

redis-cli shutdown (-p 端口)

redis-cli shutdown (-p 端口) （-a 认证密码）

3）自己定义启动文件并配置(推荐）

[[email protected] ~]# cpredis-2.8.24/utils/redis_init_script /etc/init.d/redis

注册为系统服务：

[[email protected] ~]# sed -i ‘2i #chkconfig:2345 80 90‘ /etc/init.d/redis

[[email protected] ~]# chkconfig --add redis

修改配置文件（因为路径自己定义,sed也可以）

REDISPORT=7000  #注意slave端口自己定义即可

EXEC=/usr/local/redis/bin/redis-server

CLIEXEC=/usr/local/redis/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid

CONF="/etc/redis/${REDISPORT}.conf"

脚本如下（自己配置的，大家也可在此基础上进行修改）

#!/bin/sh
#chkconfig: 2345 80 90
# Simple Redis init.d script conceivedto work on Linux systems
# as it does use of the /procfilesystem.
