Linux安装lnmp环境（Yum方式）

一、lnmp简介

LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构。

Linux是一类Unix计算机操作系统的统称，是目前最流行的免费操作系统。代表版本有：debian、centos、ubuntu、fedora、gentoo等。

Nginx是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP代理服务器。

Mysql是一个小型关系型数据库管理系统。

PHP是一种在服务器端执行的嵌入HTML文档的脚本语言。

这四种软件均为免费开源软件，组合到一起，成为一个免费、高效、扩展性强的网站服务系统。

[root@localhost ~]# ps -ef |grep nginx

7、查询Nginx监听端口

[root@localhost ~]# netstat -lntup |grep nginx

8、卸载Nginx

[root@localhost ~]# yum -y remove nginx

9、RPM方式安装升级指定版本Nginx

[root@localhost ~]# rpm -Uvh http://nginx.org/packages/centos/7/x86_64/RPMS/nginx-1.22.0-1.el7.ngx.x86_64.rpm

2、Yum安装MySQL

1）配置清华大学Yum源

[root@localhost ~]# vim /etc/yum.repos.d/mysql-community.repo

[mysql-connectors-community]name=MySQL Connectors Communitybaseurl=https://mirrors.tuna.tsinghua.edu.cn/mysql/yum/mysql-connectors-community-el7-$basearch/enabled=1gpgcheck=1gpgkey=https://repo.mysql.com/RPM-GPG-KEY-mysql[mysql-tools-community]name=MySQL Tools Communitybaseurl=https://mirrors.tuna.tsinghua.edu.cn/mysql/yum/mysql-tools-community-el7-$basearch/enabled=1gpgcheck=1gpgkey=https://repo.mysql.com/RPM-GPG-KEY-mysql[mysql-5.7-community]name=MySQL 5.7 Community Serverbaseurl=https://mirrors.tuna.tsinghua.edu.cn/mysql/yum/mysql-5.7-community-el7-$basearch/enabled=1gpgcheck=0gpgkey=https://repo.mysql.com/RPM-GPG-KEY-mysql

2）安装MySQL-5.7

[root@localhost ~]# yum -y install mysql-community-server

3）启动MySQL

[root@localhost ~]# systemctl start mysqld

4）登录MySQL

1、查看初始化后生成的密码

[root@localhost ~]# grep 'password' /var/log/mysqld.log

2022-12-14T07:48:14.697319Z 1 [Note] A temporary password is generated for root@localhost: j!#kVpr6_e:!

2、登录MySQL

[root@localhost ~]# mysql -uroot -p'j!#kVpr6_e:!'

mysql: [Warning] Using a password on the command line interface can be insecure.

3、Yum安装PHP

1）安装remi扩展源

remi源是Remi repository是包含最新版本PHP和MySQL包的Linux源，由Remi提供维护。有这个源之后，使用YUM安装或更新PHP、MySQL、phpMyAdmin等服务器相关程序的时候就非常方便了。

[root@localhost ~]# yum -y install epel-release

[root@localhost ~]# yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

2）安装YUM管理工具

[root@localhost ~]# yum -y install yum-utils

4）查看是否安装成功及php配置文件以及对应目录

[root@localhost ~]# rpm -qa |grep php74

[root@localhost ~]# rpm -ql php74-php-fpm

5）建立软连接

[root@localhost ~]# ln -sf /opt/remi/php74/root/usr/bin/php* /usr/local/bin
