Nginx安装以及使用,加载Https模块,以及gzip模块

nginx是安装在Linux下面的;

安装nginx参考了一下下面这个文档

http://www.cnblogs.com/Netsharp/p/5890170.html

如果需要加载https模块,

需要先安装openssl,以及openssl devel

yum -y install openssl openssldevel

nginx编译和安装时,需要把--with-http_ssl_module加在./configure后面;

如果需要加载gzip模块,需要把--with-http-gzip-static-module加在./configure后面;

#./configure --with-http_ssl_module

然后根据上面的那个文档就可以安装成功;


nginx的几个操作:

1.在nginx的sbin目录下面,使用sudo ./nginx -V可以查看nginx的加载项,如果加载了gzip,https,在这里就可以看出来

2.sudo ./nginx -t,在重启nginx前,检查nginx.conf配置文件语法是否正确;

3.sudo ./nginx -s reload ,是重新加载nginx的配置文件,做到平滑重启的效果;

4.sudo ./nginx -s reopen ,是重启nginx;

5.sudo ./nginx -s stop, 是关闭nginx;

6.sudo ./nginx, 启动nginx.

7.tail -f /usr/local/nginx/logs/*.log ,可以实时的打印出log日志;



下面是nginx.conf文件的内容:
