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：

user yyyadmin yyyadmin;
worker_processes 2;

error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

use epoll;
worker_connections 1024;
}

include mime.types;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log logs/access.log main;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;

# gzip压缩功能设置
gzip on; #开启gzip压缩输出
gzip_min_length 1k; #最小压缩文件大小
gzip_buffers 4 16k; #压缩缓冲区
gzip_http_version 1.0; #压缩版本（默认1.1，前端如果是squid2.5请使用1.0）
gzip_comp_level 2; #压缩等级
gzip_types text/plain text/css text/javascript application/json application/javascript application/x-javascript application/xml; #压缩类型，默认就已经包含text/html，所以下面就不用再写了，写上去也不会有问题，但是会有一个warn。
gzip_vary on;

# http_proxy 设置
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 75;
proxy_send_timeout 75;
