CentOS8安装Redis

1.下载Redis5.0.7版本

xhl是我个人在/home/xhl的目录，根据个人的参考

 [xhlc02@localhost xhl]# wget http://download.redis.io/releases/redis-5.0.7.tar.gz

2.解压包

[xhlc02@localhost xhl]# tar -xzvf redis-5.0.7.tar.gz 

3.准备编译环境

执行gcc -v检查是否安装了gcc环境，如果Linux系统没有安装gcc编译器,会提示“Command not found”。

[xhlc02@localhost redis-5.0.7]# gcc -v

安装 gcc环境

[xhlc02@localhost redis-5.0.7]# yum install gcc

安装tcl环境

[xhlc02@localhost redis-5.0.7]# yum install tcl

4.编译环境

make 后加 MALLOC的参数的原因：避免提示找不到 jemalloc/jemalloc.h

[xhlc02@localhost redis-5.0.7]# make MALLOC=libc

5.测试编译是否通过

[xhlc02@localhost redis-5.0.7]# make test

如果看到以下内容，代表通过

\o/ All tests passed without errors!

6.安装redis

[xhlc02@localhost redis-5.0.7]# cd  /usr/local
[xhlc02@localhost local]# mkdir  soft/redis5
[xhlc02@localhost local]# cd  soft/redis5
[xhlc02@localhost redis5]# mkdir bin
[xhlc02@localhost redis5]# mkdir conf
[xhlc02@localhost redis5]# cd bin/
[xhlc02@localhost bin]# cp /home/xhl/redis-5.0.7/src/redis-cli ./
[xhlc02@localhost bin]# cp /home/xhl/redis-5.0.7/src/redis-server ./
[xhlc02@localhost bin]# cd ../conf/
[xhlc02@localhost conf]# cp /home/xhl/redis-5.0.7/redis.conf ./

7.配置redis.conf

[root@localhost conf]# vi redis.conf

按G或者shift+g,跳转到末尾，将以下内容粘贴

# daemonize no
daemonize yes
# maxmemory <bytes>
maxmemory 128MB 

8.运行redis

[xhlc02@localhost conf]# /usr/local/soft/redis5/bin/redis-server /usr/local/soft/redis5/conf/redis.conf

9.编写service,使redis可以用systemd方式启动和管理

[xhlc02@localhost /]# vim /lib/systemd/system/redis.service

粘贴内容

[Unit]
Description=Redis
After=network.target
[Service]
Type=forking
PIDFile=/var/run/redis_6379.pid
ExecStart=/usr/local/soft/redis5/bin/redis-server/usr/local/soft/redis5/conf/redis.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

10.重载服务

[xhlc02@localhost /]# systemctl daemon-reload

11.管理redis

启动
systemctl start redis    
查看状态
systemctl status redis
使开机启动
systemctl enable redis
