Centos7安装Redis-单节点

1、安装 gcc 编译环境

由于 Redis 使用 C 语言开发，所以官网下载的源码需要进行编译，编译依赖 gcc 环境，如果没有 gcc 环境，则需要安装。

​[root@CentOS ~]# yum -y install gcc

2、下载 redis 安装包

​[root@CentOS local]# wget http://download.redis.io/releases/redis-4.0.8.tar.gz

3、解压安装包

​[root@CentOS local]# tar -zxvf redis-4.0.8.tar.gz     # 解压安装包
redis-4.0.8/
redis-4.0.8/.gitignore
redis-4.0.8/00-RELEASENOTES
redis-4.0.8/BUGS
redis-4.0.8/CONTRIBUTING
redis-4.0.8/COPYING
redis-4.0.8/INSTALL
redis-4.0.8/MANIFESTO
......（略去内容）......
[root@CentOS local]# ll        # 查看目录文件信息

drwxr-xr-x. 2 root root       6 11月  5 2016 src
[root@CentOS local]# 

​

4、编译并安装文件

​[root@CentOS local]# cd redis-4.0.8/        # 进入解压后的目录
[root@CentOS redis-4.0.8]# make             # 执行编译
......（略去内容）......
CC lazyfree.o
    CC module.o
    CC evict.o
    CC expire.o
    CC geohash.o
    CC geohash_helper.o
    CC childinfo.o
    CC defrag.o

    LINK redis-server
    INSTALL redis-sentinel
    CC redis-cli.o
    LINK redis-cli
    CC redis-benchmark.o
    LINK redis-benchmark
    INSTALL redis-check-rdb
    INSTALL redis-check-aof

Hint: It's a good idea to run 'make test' ;)            # 如果编译成功，会看到此行信息提示

make[1]: 离开目录“/usr/local/redis-4.0.8/src”
[root@CentOS redis-4.0.8]# make install     # 执行安装，默认会安装到 /usr/local/bin 目录中
cd src && make install
make[1]: 进入目录“/usr/local/redis-4.0.8/src”
    CC Makefile.dep
make[1]: 离开目录“/usr/local/redis-4.0.8/src”
make[1]: 进入目录“/usr/local/redis-4.0.8/src”

Hint: It's a good idea to run 'make test' ;)        # 如果安装成功，会看到此行信息提示

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
make[1]: 离开目录“/usr/local/redis-4.0.8/src”
[root@CentOS redis-4.0.8]#

​

5、将 redis 设置为系统服务，并开机启动

​[root@CentOS redis-4.0.8]# ./utils/install_server.sh         # 执行 install_server.sh 脚本，之后一直回车确认采用默认配置即可
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 [/usr/local/bin/redis-server] 
Selected config:
Port           : 6379
Config file    : /etc/redis/6379.conf            # redis实例默认的配置文件
Log file       : /var/log/redis_6379.log         # redis实例的日志文件
Data dir       : /var/lib/redis/6379             # redis实例的数据存储目录
Executable     : /usr/local/bin/redis-server     # redis_server 执行路径
Cli Executable : /usr/local/bin/redis-cli        # redis_cli 执行路径
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
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!            # 提示已安装成功
[root@CentOS redis-4.0.8]# 

6、编辑 redis 实例默认的配置文件，修改配置项如下

​daemonize yes                # 将 redis 实例作为后台进程运行
bind 0.0.0.0                 # 允许任何远程主机访问
requirepass 123456           # 登录密码

7、重启 redis 服务，并将 6379 端口添加到防火墙中

​[root@CentOS redis-4.0.8]# service redis_6379 restart    # 重启 redis 服务
Stopping ...
Redis stopped
Starting Redis server...
[root@CentOS redis-4.0.8]# firewall-cmd --zone=public --add-port=6379/tcp --permanent    # 添加 6379 端口到防火墙中
success
[root@CentOS redis-4.0.8]# firewall-cmd --reload    # 重新载入防火墙信息
success
[root@CentOS redis-4.0.8]#
