What are the methods to start redis in Linux?

1.直接启动进入redis根目录，执行命令: #加上‘&’号使redis以后台程序方式运行

 nohup redis-server &

Copy after login

2.通过指定配置文件启动可以为redis服务启动指定配置文件，例如配置为/etc/redis/6379.conf 进入redis根目录，输入命令：

 ./redis-server /etc/redis/6379.conf

Copy after login

#如果更改了端口，使用redis-cli客户端连接时，也需要指定端口，例如：

 redis-cli -p 6380

Copy after login

3.使用redis启动脚本设置开机自启动启动脚本 redis_init_script 位于位于Redis的 /utils/ 目录下，redis_init_script脚本代码如下：

 #!/bin/sh # # Simple Redis init.d script conceived to work on Linux systems # as it does use of the /proc filesystem.   #redis服务器监听的端口 REDISPORT=6379   #服务端所处位置 EXEC=/usr/local/bin/redis-server   #客户端位置 CLIEXEC=/usr/local/bin/redis-cli   #redis的PID文件位置，需要修改 PIDFILE=/var/run/redis_${REDISPORT}.pid   #redis的配置文件位置，需将${REDISPORT}修改为文件名 CONF="/etc/redis/${REDISPORT}.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         ;;     *)         echo "Please use start or stop as first argument"         ;; esac

Copy after login

根据启动脚本，将修改好的配置文件复制到指定目录下，用root用户进行操作：

 mkdir /etc/redis 
 cp redis.conf /etc/redis/6379.conf

Copy after login

将启动脚本复制到/etc/init.d目录下，本例将启动脚本命名为redisd（通常都以d结尾表示是后台自启动服务）。

 cp redis_init_script /etc/init.d/redisd

Copy after login

设置为开机自启动，直接配置开启自启动 chkconfig redisd on 发现错误： service redisd does not support chkconfig

解决办法，在启动脚本开头添加如下注释来修改运行级别：

 #!/bin/sh 
 # chkconfig:   2345 90 10

Copy after login

再设置即可

 #设置为开机自启动服务器 
 chkconfig redisd on 
 #打开服务 
 service redisd start 
 #关闭服务 
 service redisd stop

Copy after login
