Centos下配置Redis开机启动脚本

1、下载安装

wget http://redis.googlecode.com/files/redis-2.2.13.tar.gz 
tar -zxf redis-2.2.13.tar.gz 
cd redis-2.2.13 
make 
sudo make install  
cp redis.conf /etc

install的时候，redis的命令会被拷贝到/usr/local/bin下面

2，建立用户与日志目录

第一次启动Redis前，建议为Redis单独建立一个用户，并新建data和日志文件夹

sudo useradd redis 
sudo mkdir -p /var/lib/redis 
sudo mkdir -p /var/log/redis 
sudo chown redis.redis /var/lib/redis ＃db文件放在这里，要修改redis.conf 
sudo chown redis.redis /var/log/redis

3，配置init脚本

其实github上很多老外写好的启动脚本，不过大部分都是ubuntu的，对于Centos。

经过修改，如下：

########################### 
PATH=/usr/local/bin:/sbin:/usr/bin:/bin 
   
REDISPORT=6379 
EXEC=/usr/local/bin/redis-server 
REDIS_CLI=/usr/local/bin/redis-cli 
   
PIDFILE=/var/run/redis.pid 
CONF="/etc/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 $CONF 
    fi 
    if [ "$?"="0" ]  
    then 
       echo "Redis is running..." 
    fi 
    ;; 
  stop) 
    if [ ! -f $PIDFILE ] 
    then 
        echo "$PIDFILE does not exist, process is not running" 
    else 
        PID=$(cat $PIDFILE) 
        echo "Stopping ..." 
        $REDIS_CLI -p $REDISPORT SHUTDOWN 
        while [ -x ${PIDFILE} ] 
        do 
          echo "Waiting for Redis to shutdown ..." 
          sleep 1 
        done 
        echo "Redis stopped" 
    fi 
    ;; 
  restart|force-reload) 
    ${0} stop 
    ${0} start 
    ;; 
 *) 
  echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2 
    exit 1 
esac 
##############################

把上述代码存为redis,放到/etc/init.d/下面

chmod +x /etc/init.d/redis

其实做成服务启动，也是调用redis-server，如果想让它在后台作为daemon运行，那么

需要修改redis.conf,将 daemonize no 改为 daemonize yes

4，设定开机启动服务

sudo chkconfig redis on

5，启动,停止redis

service redis start  #或者 /etc/init.d/redis start 
service redis stop  #或者 /etc/init.d/redis stop

6，测试redis

redis-cli  
redis 127.0.0.1:6379> set foo 123 
OK 
redis 127.0.0.1:6379> get foo 
"123" 
redis 127.0.0.1:6379> exit
