编译安装Nginx
1、安装常见的工具和库(GCC、PCRE、zlib、OpenSSL)
Nginx是一个由C语言编写的，所以需要一个编译工具如GNU的GCC
[root@www ~]# yum install gcc
或：
[root@www ~]# apt-get install gcc
Nginx的Rewrite模块和HTTP核心模块会使用到PCRE正则表达式语法
[root@www ~]# yum install pcre pcre-devel
或
[root@www ~]# apt-get install libpcre3 libpcre3-dev
Nginx的各种模块中需要使用gzip压缩
[root@www ~]# yum install zlib zlib-devel
[root@www ~]# apt-get install zliblg zliblg-dev
OpenSSL提供安全网页，使用SSL/TLS安全套接字
[root@www ~]# yum install openssl openssl-devel
[root@www ~]# apt-get install openssl openssl-dev

3、编译安装

> --with-http_ssl_module --with-http_stub_status_module
[root@www nginx-1.14.0]# make && make install
4、控制Nginx服务
启动
[root@www sbin]# /usr/local/nginx-1.14.0/sbin/nginx
[root@www sbin]# ps -aux |grep nginx
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQ
root 9699 0.0 0.1 46860 1192 ? Ss 21:52 0:00 nginx: master process /usr/local/nginx-1.14.0/sbin/nginx
nginx 9700 0.0 0.1 47292 1772 ? S 21:52 0:00 nginx: worker process
存在两个进程：
1、master进程
2、工作进程
[root@www sbin]# netstat -lntup |grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 9699/nginx
Nginx监听tcp80端口
停止守护进程
nginx -s stop //立即停止守护进程（TERM信号）
nginx -s quit //温和地停止守护进程（QUIT信号）
nginx -s reopen //重新打开日志文件
nginx -s reload //重新载入配置文件
使用kill 或 killall命令
nginx -t //测试配置文件
nginx -t -c file //使用额外的配置文件测试
