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..tar.gz     # 解压安装包
redis-4.0./
redis-4.0./.gitignore
redis-4.0./-RELEASENOTES
redis-4.0./BUGS
redis-4.0./CONTRIBUTING
redis-4.0./COPYING
redis-4.0./INSTALL
redis-4.0./MANIFESTO
......（略去内容）......
[root@CentOS local]# ll        # 查看目录文件信息
总用量
drwxr-xr-x.  root root        2月   : bin
drwxr-xr-x.  root root        11月    etc
drwxr-xr-x.  root root        11月    games
drwxr-xr-x.  root root        11月    include
drwxr-xr-x.  root root        11月    lib
drwxr-xr-x.  root root        11月    lib64
drwxr-xr-x.  root root        11月    libexec
drwxrwxr-x.  root root     2月    : redis-4.0.        # 该目录为解压后的目录
-rw-r--r--.  root root  2月    : redis-4.0..tar.gz
drwxr-xr-x.  root root        11月    sbin
drwxr-xr-x.  root root       1月   : share
drwxr-xr-x.  root root        11月    src
[root@CentOS local]# 

​

4、编译并安装文件

​[root@CentOS local]# cd redis-4.0./        # 进入解压后的目录
[root@CentOS redis-4.0.]# 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
    CC siphash.o
    CC rax.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[]: 离开目录“/usr/local/redis-4.0./src”
[root@CentOS redis-4.0.]# make install     # 执行安装，默认会安装到 /usr/local/bin 目录中
cd src && make install
make[]: 进入目录“/usr/local/redis-4.0./src”
    CC Makefile.dep
make[]: 离开目录“/usr/local/redis-4.0./src”
make[]: 进入目录“/usr/local/redis-4.0./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[]: 离开目录“/usr/local/redis-4.0./src”
[root@CentOS redis-4.0.]#

​

5、将 redis 设置为系统服务，并开机启动

​[root@CentOS redis-4.0.]# ./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: []
Selecting default:
Please select the redis config file name [/etc/redis/.conf]
Selected default - /etc/redis/.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/]
Selected default - /var/lib/redis/
Please select the redis executable path [/usr/local/bin/redis-server]
Selected config:
Port           :
Config file    : /etc/redis/.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/             # 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/.conf => /etc/init.d/redis_6379
Installing service...
Successfully added to chkconfig!
Successfully added to runlevels !
Starting Redis server...
Installation successful!            # 提示已安装成功
[root@CentOS redis-4.0.]# 

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            # 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.]# service redis_6379 restart    # 重启 redis 服务
Stopping ...
Redis stopped
Starting Redis server...
[root@CentOS redis-4.0.]# firewall-cmd --zone=public --add-port=/tcp --permanent    # 添加  端口到防火墙中
success
[root@CentOS redis-4.0.]# firewall-cmd --reload    # 重新载入防火墙信息
success
[root@CentOS redis-4.0.]#
