systemctl stop firewalld
systemctl disable firewalld
setenforce 0
2、安装依赖包
yum -y install gcc pcre-devel openssl-devel zlib-devel openssl openssl-devel
3、创建运行用户、组
（Nginx 服务程序默认以 nobody 身份运行，建议为其创建专门的用户账号，以便更准确地控制其访问权限）
useradd -M -s /sbin/nologin nginx
4、编译安装Nginx
cd /opt
tar zxvf nginx-1.22.0.tar.gz -C /opt/
cd nginx-1.22.0/
./configure --prefix=/usr/local/nginx
–user=nginx
–group=nginx
–with-http_ssl_module
–with-http_v2_module
–with-http_realip_module
–with-http_stub_status_module
–with-http_gzip_static_module
–with-pcre
–with-stream
–with-stream_ssl_module
–with-stream_realip_module
make && make install
chown -R nginx.nginx /usr/local/nginx #修改权限
ln -s /usr/local/nginx/sbin/nginx /usr/sbin/ #让系统识别nginx的操作命令
