本博主要示例通过编译nginx官网的源码的方式，安装nginx程序包。
如果想通过yum方式安装nginx，可查看官方文档 http://nginx.org/en/linux_packages.html
系统环境
linux内核版本 3.10.0-514.el7.x86_64
centos系统版本 CentOS Linux release 7.3.1611 (Core)
IP地址 172.16.55.7/16 192.168.55.135/24
准备
关闭selinux，清空iptables规则（对这些熟悉的同学可以不做处理）
1.下载nginx源码
~]# wget http://nginx.org/download/nginx-1.10.3.tar.gz
2.安装nginx依赖的程序包
~]# yum install -y pcre-devel openssl-devel zlib-devel
3.创建nginx系统用户
~]# useradd -r -s /sbin/nologin nginx
4.解压nginx源码包
~]# tar xvf nginx-1.10.3.tar.gz
5.根据具体需求编译源码
nginx-1.10.3]# ./configure --prefix=/usr/local/nginx --sbin-path=/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_module --with-http_dav_module --with-http_stub_status_module --with-threads --with-file-aio
nginx-1.10.3]# make && make install
6.启动nginx服务
[root@localhost nginx]# nginx # 启动nginx [root@localhost nginx]# ps aux | grep nginx root 13324 0.0 0.0 45428 1116 ? Ss 09:52 0:00 nginx: master process nginx nginx 13325 0.0 0.0 47964 1956 ? S 09:52 0:00 nginx: worker process root 13336 0.0 0.0 112648 960 pts/3 R+ 09:52 0:00 grep --color=auto nginx
[root@localhost nginx]# ss -tnlp | grep nginx # 监听80端口
LISTEN 0 128 *:80 *:* users:(("nginx",pid=13325,fd=6),("nginx",pid=13324,fd=6))
7.访问nginx服务
[root@localhost nginx]# curl 172.16.55.7 <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working. Further configuration is required.</p> <p>For online documentation and support please refer to <a href="http://nginx.org/">nginx.org</a>.<br/> Commercial support is available at <a href="http://nginx.com/">nginx.com</a>.</p> <p><em>Thank you for using nginx.</em></p> </body> </html>
