centos 下Redis 安装+远程访问+开机自启，centosredis

一．安装redis

1、下载redis安装包

可去官网http://redis.io ，也可通过wget命令

cd /usr/local/soft/
wget http://download.redis.io/releases/redis-4.0.6.tar.gz

2、解压

tar xzf redis-4.0.6.tar.gz

3、编译、安装

cd redis-4.0.6 
make

二．远程访问

1、将redis配置文件拷贝到etc下

cp /usr/local/soft/redis-4.0.6/src/redis.conf /etc/ 

2、修改配置文件

#bind 127.0.0.1 注释掉使所有的ip访问redis
protected-mode yes

3、关闭防火墙

service iptables status
chkconfig iptables off

4、关机重启

reboot

三．开机自启

1、设置redis.conf中daemonize为yes,确保守护进程开启。

2、编写开机自启动脚本

vi /etc/init.d/redis

脚本如下：

 chkconfig: 2345 10 90  
# description: Start and Stop redis   
  
PATH=/usr/local/bin:/sbin:/usr/bin:/bin   
REDISPORT=6379  
EXEC=/usr/local/soft/redis-4.0.6/src/redis-server   
REDIS_CLI=/usr/local/soft/redis-4.0.6/src/redis-cli   
 
PIDFILE=/var/run/redis.pid   
CONF="/etc/redis.conf"  
AUTH="1234"  

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 exists, process is not running."  
                else  
                        PID=$(cat $PIDFILE)   
                        echo "Stopping..."  
                       $REDIS_CLI -p $REDISPORT  SHUTDOWN    
                        sleep 2  
                       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

3、写完后保存退出VI

4、设置权限

chmod 755 redis

5、启动测试

/etc/init.d/redis start

启动成功会提示如下信息：

Starting Redis server...
Redis is running...

使用redis-cli测试：

[root@rk ~]# /usr/redisbin/redis-cli
127.0.0.1:6379> set foo bar
OK
127.0.0.1:6379> get foo
"bar"
127.0.0.1:6379> exit

6、设置开机自启动

chkconfig redis on

7、关机重启测试

reboot

然后在用redis-cli测试即可。
