Centos7.6编译安装redis-6.2.4_第2张图片 通过上图,我们可以很容易的看出,redis安装到了/usr/local,/usr/local/bin,/usr/local/share,/usr/local/include,/usr/local/lib,/usr/local/share/man目录下。

 检查make编译步骤中是否有问题,确保服务的编译正常

[root@iZ8hmg40voakzkZ src]# make test

切换到utils目录下,执行redis初始化脚本install_server.sh

[root@redis redis-6.2.4]# cd utils/
[root@redis utils]# ./install_server.sh

出现报错:

 解决办法:

编辑文件,注释76-83行内容

[root@redis utils]# vim install_server.sh 

 再次执行

[root@redis utils]# ./install_server.sh

通过上面的安装过程,我们可以看出redis初始化后:

redis配置文件为/etc/redis/6379.conf

日志文件为/var/log/redis_6379.log

数据文件dump.rdb存放到/var/lib/redis/6379目录下

启动脚本为/etc/init.d/redis_6379


现在我们要使用systemd,所以在 /etc/systems/system 下创建配置文件

[root@redis utils]# vim /etc/systemd/system/redis_6379.service
[Unit]
Description=Redis on port 6379
[Service]
Type=forking
ExecStart=/etc/init.d/redis_6379 start
ExecStop=/etc/init.d/redis_6379 stop
[Install]
WantedBy=multi-user.target

注释:

[Unit] 表示这是基础信息

Description 是描述

[Service] 表示这里是服务信息

Type=forking是后台运行的形式

ExecStart 是启动服务的命令

ExecStop 是停止服务的指令

[Install] 表示这是是安装相关信息

WantedBy 是以哪种方式启动:multi-user.target表明当系统以多用户方式(默认的运行级别)启动时,这个服务需要被自动运行。

查看redis版本

[root@redis ~]# redis-cli --version

配置Redis 

设置redis监听的地址,添加监听redis主机的ip

考虑到安全性,我们需要启用peiredis的密码验证功能requirepass参数

重启服务

[root@redis redis]# systemctl restart redis_6379.service 
[root@redis redis]# netstat -anptu | grep redis
tcp        0      0 172.17.1.13:6379        0.0.0.0:*               LISTEN      32358/redis-server

Redis配置文件配置完毕后,我们来启动redis并进行简单的操作

[root@redis ~]# redis-cli -h 172.17.1.13 -p 6379 -a Qaz@2023Wzx
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.

OK
172.17.1.13:6379> get name
"list"
172.17.1.13:6379>

-h:指定连接地址 -p:指定端口号 -a:指定密码

keys *是查看redis所有的键值对

set namelisi添加一个键值name,内容为lisi

get name查看name这个键值的内容
