CentOS7下Redis安装

Redis安装

下载Redis

http://redis.io/ 下载最新版的Redis

也可以使用wget直接下载redis

wget http://download.redis.io/releases/redis-3.2.0.tar.gz

安装Redis

解压Redis

tar zxvf redis-3.2.0.tar.gz
mv redis-3.2.0 redis
cd redis

编译安装

yum -y install make gcc-c++ cmake bison-devel ncurses-devel libaio bison libaio libaio-devel perl-Data-Dumper net-tools

make

出现下面结果表示成功

make install

此时Redis已经安装成功，直接执行redis-server就可以启动redis

Redis使用脚本

当Redis多实例启动时，没有脚本需得启动多个redis.conf文件，比较麻烦，使用脚本启动比较方便。

脚本步骤

1.  在/etc/rc.d/init.d/目录下新建redis文件，将脚本内容拷贝进去
2. chkconfig --add redis   #注册服务
3. chkconfig --level 345 redis on  #指定服务在3、4、5级别运行
4. systemctl daemon-reload
5. 多端口时新建redis.conf文件命名方法建议为“redis-6381.conf”这种格式以便跟脚本中对应，如以其他命名，脚本需做相应更改。

脚本参数

      service redis -p [port]  [start|stop|status|restart]
参数说明：
         -p [port] : 指定redis实例的端口，用于多实例的服务器
         start：启动指定端口的Redis服务
         stop：停止指定端口的Redis服务
         status：进程状态
         restart：先关闭Redis服务,再启动Redis服务
注：不指定端口时，脚本默认指定启动6379端口的redis

使用示例

service redis -p 6381 start  #启动6381端口实例的redis
 /etc/init.d/redis  start  #默认启动6379端口实例的redis

注意你安装Redis的目录，要对脚本中目录做出相应更改。
