在Linux上安装Redis

环境

Redis Version：3.0.1及以上
OS：Centos 7

步骤

1. 下载到指定目录并解压

> cd /usr/src
> wget -c http://download.redis.io/redis-stable.tar.gz
> tar xvzf redis-stable.tar.gz

2. 构建

> cd redis-stable
> make && make install

如果由于没有安装gcc导致make报错，在安装make之后重新构建可能会报jemalloc/jemalloc.h相关错误，可参考
http://unix.stackexchange.com/questions/94479/jemalloc-and-other-errors-making-redis-on-centos-6-4进行修复

3. 运行安装脚本

> utils/install_server.sh

脚本会有一系列引导

Please select the redis port for this instance: [6379]

回车选择6379作为默认端口

Please select the redis config file name [/etc/redis/6379.conf] 

输入/etc/redis/redis_6379.conf，作为新的配置文件，回车

Please select the redis log file name [/var/log/redis_6379.log]

回车，继续

Please select the data directory for this instance [/var/lib/redis/6379]

回车，继续

Please select the redis executable path [/usr/local/bin/redis-server]

回车，继续，屏幕输出配置如下，

Selected config:
Port           : 6379
Config file    : /etc/redis/redis_6379.conf
Log file       : /var/log/redis_6379.log
Data dir       : /var/lib/redis/6379
Executable     : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.

确认无误，回车，屏幕继续输出

Copied /tmp/6379.conf => /etc/init.d/redis_6379
Installing service...
Successfully added to chkconfig!
Successfully added to runlevels 345!
Starting Redis server...
Installation successful!

安装成功

4. 验证是否安装成功

> /etc/init.d/redis_6379 status

输出

Redis is running (27186)

查看server信息

> redis-cli -p 6379 info server

看是否有正确输出

测试是否能写入和读取数据

> redis-cli
127.0.0.1:6379> set test 1
OK
127.0.0.1:6379> get test
"1"

ok，没问题，至此，安装成功
