Redis install and config

kllhi

  本文参照官方文档。最初安装redis时，编译后只能在当前目录使用，并且 init 脚本也是参照网络而写。最近在官方看了部分文档，对其编译与使用过程有了进一步了解，遂整理此文，以备查阅。

准备和说明：
    系统：centos6.5
    软件源码目录：/usr/local/src
    软件安装目录：/usr/local/bin
    软件官网：redis.io
    软件下载地址及版本(截至本文发布最新稳定版)：http://download.redis.io/releases/redis-3.0.6.tar.gz


软件安装：

1 2 3 4 5 6 7 8 9 10 11 12 13 14

$wget -c  -P /usr/local/src $cd /usr/local/src $tar zxvf redis-3.0.6.tar.gz $cd /usr/local/src/redis-3.0.6 #查看REDME得知 #编译安装到当前路径src目录 $sudo make                            或 #编译redis并安装到目录/usr/local/bin #此文采用此种方式 $sudo make install                     或 #编译redis并安装到自定义目录/usr/local/redis $sudo make prefix=/usr/local/redis

经过上面的编译，生成以下二进制文件

• redis-server is the Redis Server itself.
  
• redis-sentinel is the Redis Sentinel executable (monitoring and failover).
  
• redis-cli is the command line interface utility to talk with Redis.
  
• redis-benchmark is used to check Redis performances.
  
• redis-check-aof and redis-check-dump are useful in the rare event of corrupted data files.
  
  

完善安装：
在完成以上编译，就已完成redis软件安装，可使用 ./redis-server 运行 redis 服务。但在生产环境这并不可取，所以需要后续工作进行完善。

如只使用 make 编译，请将 server 和 cli 拷贝到 /usr/local/bin 下：

1 2	$sudo cp src/redis-server /usr/local/bin $sudo cp src/redis-cli /usr/local/bin

创建配置文件和数据存储目录：

1 2	$sudo mkdir /etc/redis $sudo mkdir /var/redis

复制 init 脚本到 /etc/init.d 并使用 redis 加实例端口命名

1	$sudo utils/redis_init_script /etc/init.d/redis_6379

编辑 init 脚本，修改确认 REDISPORT 端口和 PIDFILE 、CONF 文件路径及名称，增加 chkconfig 级别

1	$sudo vim /etc/init.d/redis_6379

/etc/init.d/redis_6379

复制配置模板到 /etc/redis 目录，并以运行实例端口命名

1	$sudo cp redis.conf /etc/redis/6379.conf

创建运行实例工作目录

1	$sudo mkdir /var/redis/6379

编辑配置文件，确保以下更改

• Set daemonize to yes (by default it is set to no).
  
• Set the pidfile to /var/run/redis_6379.pid (modify the port if needed).
  
• Change the port accordingly. In our example it is not needed as the default port is already 6379.
  
• Set your preferred loglevel.
  
• Set the logfile to /var/log/redis_6379.log
  
• Set the dir to /var/redis/6379 (very important step!)

将 redis 加入系统服务，并设置默认运行级别

1 2	chkconfig --add redis_6379 chkconfig --level 2345 redis_6379 on

启动 redis 服务

1	$sudo service redis_6379 start

至此完成安装及配置，可使用 redis-cli 链接 redis 服务测试
