Redis 安装

mkdir -p /opt/software
cd /opt/software
wget https://download.redis.io/releases/redis-4.0.14.tar.gz

tar -zxvf redis-4.0.14.tar.gz

/opt/software/redis-4.0.14

查看 README.md 文档

make 

make 过程可能由于没有安装gcc出错
yum install -y gcc 
先执行 make distclean
再重新执行make 

make 成功后redis-server、redis-cli 等命令会安装在src目录下

将 redis 二进制安装到指定目录
make install PREFIX=/opt/moudle/redis

配置环境变量
vi /etc/profile
export REDIS_HOME=/opt/moudle/redis
export PATH=$PATH:$REDIS_HOME/bin
保存退出
source /etc/profile

这样我们就可以在任意目录使用 redis 相关命令了

在生产环境需要配置 redis 为系统服务

cd utils
./install_server.sh 执行安装脚本，会出现如下信息

Welcome to the redis service installer
This script will help you easily set up a running redis server

Please select the redis port for this instance: [6379] 
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf] 
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log] 
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379] 
Selected default - /var/lib/redis/6379
Please select the redis executable path [/opt/moudle/redis/bin/redis-server] 
Selected config:
Port           : 6379
Config file    : /etc/redis/6379.conf
Log file       : /var/log/redis_6379.log
Data dir       : /var/lib/redis/6379
Executable     : /opt/moudle/redis/bin/redis-server
Cli Executable : /opt/moudle/redis/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.

可以看到redis 配置文件、日志文件、数据目录、可执行脚本等。
最后一步，回车确认。

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!

可以看到 redis 已经安装并启动成功。

查看 redis 进程
ps -ef|grep redis 

root      11739      1  0 14:59 ?        00:00:00 /opt/moudle/redis/bin/redis-server 127.0.0.1:6379

查看 redis 实例状态
service redis_6379 status

可以再次使用 install_server.sh 脚本在同一台机器上安装不同端口的 redis 实例。
