Redis的多种启动方式比较！推荐

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）
[b]#daemonize yes（也可配置文件修改此参数）[/b]
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_${REDISPORT}.pid
CONF="/etc/redis/${REDISPORT}.conf"

case "$1" in
start)
if [ -f $PIDFILE ]
then
echo -e "\033[31m $PIDFILEexists, process is already running or crashed \033[0m"
else
echo -e "\033[32m Waitingfor Redis to start...\033[0m"
$EXEC $CONF
if [ $? -eq 0 ]
then
echo -e "\033[32m Redis isalready started successfully! \033[0m"
else
echo -e "\033[31m Redisstart fail \033[0m"
fi
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo -e "\033[31m $PIDFILEdoes not exist, process is not running \033[0m"
else
PID=$(cat $PIDFILE)
echo -e "\033[32m Waitingfor Redis to stop ... \033[0m"
$CLIEXEC -p $REDISPORT  shutdown
while [ -x /proc/${PID} ]
do
echo -e "\033[32mWaiting for Redis to shutdown ... \033[0m"
sleep 1
done
echo -e "\033[32m Redis isalready stopped successfully! \033[0m"
fi
;;
status)
ps aux|grep redis-server|grep-v grep &>/dev/null
if [ $? -eq 0 ]
then
echo -e "\033[32m Redisis running... \033[0m"

$EXEC $CONF

查看redis状态，启动，关闭，重启

[root@redis1 ~]# /etc/init.d/redis status
Redis is running...
[root@redis1 ~]# /etc/init.d/redis stop
Waiting for Redis to stop ...
Waiting for Redis to shutdown ...
Redis is already stopped successfully!
[root@redis1 ~]# /etc/init.d/redis start
Waiting for Redis to start...
Redis is already started successfully!
[root@redis1 ~]# /etc/init.d/redis restart
Redis is already stopped successfully!
Redis is already started successfully!
[root@redis1 ~]#
[root@redis1 ~]# ps aux|grep redis-server|grep -v grep
root       2881  0.1  0.1 128296  1692 ?        Ssl  12:45   0:01 /usr/local/redis/bin/redis-server *:7000
[root@redis1 ~]#
