1. lnmp简介
LNMP是指一组通常一起使用来运行动态网站或者服务器的自由软件名称首字母缩写。L指Linux，N指Nginx，M一般指MySQL，也可以指MariaDB，P一般指PHP，也可以指Perl或Python。
LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构
linux是Unix计算机操作系统的统称，是目前最流行的免费的操作系统，代表有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。

2.3 解压nginx的rpm包
[root@localhost ~]# tar -xzf nginx-1.20.1.tar.gz -C /usr/local
2.4 创建系统用户nginx
[root@localhost ~]# useradd -r -M -s /sbin/nologin nginx
2.5 创建日志存放目录
[root@localhost ~]# mkdir -p /var/log/nginx
[root@localhost ~]# chown -R nginx.nginx /var/log/nginx
2.6 编译安装
[root@localhost nginx-1.20.1]# ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-debug \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_image_filter_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--http-log-path=/var/log/nginx/access.log \
--error-log-path=/var/log/nginx/error.log
[root@localhost nginx-1.20.1]# make && make install
2.7 提供service文件，使用systemctl控制nginx
cat > /usr/lib/systemd/system/nginx.service << EOF
[Unit]
Description=Nginx server daemon
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecStop=/usr/local/nginx/sbin/nginx -s quit
ExecReload=/bin/kill -HUP \$MAINPID
[Install]
WantedBy=multi-user.target
EOF
// 执行完上面的命令之后再执行下面的命令，使systemctl命令生效
systemctl daemon-reload
systemctl enable --now nginx.service
3. 安装mysql
3.1 安装依赖包

3.10 生成MySQL配置文件
[root@localhost local]# cat > /etc/my.cnf << EOF
[mysqld]
basedir = /usr/local/mysql
datadir = /opt/data
socket = /tmp/mysql.sock
port = 3306
pid-file = /opt/data/mysql.pid
user = mysql
skip-name-resolve
EOF
3.11 配置服务启动的脚本
[root@localhost ~]# vim /usr/local/mysql/support-files/mysql.server
找到basedir和datadir然后添加下面的内容
basedir=/usr/local/mysql
datadir=/opt/data
3.12 配置系统服务使用systemctl来管理MySQL
[root@localhost ~]# cp /usr/lib/systemd/system/sshd.service /usr/lib/systemd/system/mysqld.service
[root@localhost ~]# cat /usr/lib/systemd/system/mysqld.service
[Unit]
Description=mysql server daemon
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/mysql/support-files/mysql.server start
ExecStop=/usr/local/mysql/support-files/mysql.server stop
ExecReload=/bin/kill -HUP $MAINPID
[Install]
WantedBy=multi-user.target
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl enable --now mysqld.service
设置数据库密码
