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）
[root@redis1 ~]# cpredis-2.8.24/utils/redis_init_script /etc/init.d/redis
注册为系统服务：
[root@redis1 ~]# sed -i '2i #chkconfig:2345 80 90' /etc/init.d/redis
[root@redis1 ~]# 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.
REDISPORT=7000
EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli
PIDFILE=/var/run/redis_${REDISPORT}.pid
