1、将压缩包上传到服务器
nginx-1.21.3.tar.gz压缩包，上传到/usr/local/目录
2、安装依赖
yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel
3、编译安装
tar -zxvf nginx-1.21.3.tar.gz
进入解压后目录执行编译
cd nginx-1.21.3
./configure --with-http_ssl_module
执行make install 命令
make install
4、启动
进入实际安装目录，看看，并在其sbin目录下执行启动nginx
cd /usr/local/nginx/sbin
运行命令启动Nginx
./nginx
5、Nginx加入systemctl方式自启动
1.建立服务文件
vim /usr/lib/systemd/system/nginx.service
新建文件，把下面文件内容放到文件中
[Unit] Description=nginx After=network.target [Service] Type=forking ExecStart=/usr/local/nginx/sbin/nginx ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s QUIT $MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target
2. 文件设为755权限并使文件生效
chmod 755 /usr/lib/systemd/system/nginx.service systemctl daemon-reload
3.设置开机启动
systemctl enable nginx.service
4.设置upload路径权限，使上传图片可读
chmod 755 -R /upload
配置nginx.conf 
只有返回类似 Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /etc/systemd/system/nginx.service提示才能够确定设置成功。如果不是请检查上面的文件
5. 其他可能用到的命令
systemctl is-enabled servicename.service #查询服务是否开机启动 systemctl enable *.service #开机运行服务 systemctl disable *.service #取消开机运行 systemctl start *.service #启动服务 systemctl stop *.service #停止服务 systemctl restart *.service #重启服务 systemctl reload *.service #重新加载服务配置文件 systemctl status *.service #查询服务运行状态 systemctl --failed #显示启动失败的服务
6、Nginx配置文件
文件位置在（前提是按照文档安装，即Nginx安装目录下的conf文件夹）
/usr/local/nginx/conf
