nginx安装

一，下载解压步骤这里省略
二、安装
root用户进到nginx目录输入以下指令

./configure

make && sudo make install

三、设置开机自动启动

 vi /etc/systemd/system/nginx.service

[Unit]
Description=nginx-server
After=network.target[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true[Install]
WantedBy=multi-user.target

重载系统服务

systemctl daemon-reload

开启开机启动

systemctl enable nginx

四、以下是nginx配置文件根据项目需求写

worker_processes  1;#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {worker_connections  1024;

注意：用systemctl启动服务nginx，网站报403错，直接命令运行nginx启动没错。两个原因，1，启动用户和用户名不一样，conf加user=root（与这个无关）。2，主要原因还是selinux的问题
403报错，权限问题，
巨坑：SELinux设置为开启状态（enabled）的原因。
