nginx安装和配置反向代理服务器

前端时间做了两个微信项目，部署在同一个服务器上了。由于需要和微信对接，都需要用到80端口，所以就用Nginx配置了一个反向代理服务器。折腾了一下午，下面把配置的步骤和信息分享出来供大家参考。

获取Nginx

可以在Nginx官方网站（http://nginx.org/en/download.html）获取Nginx源码包。

CHANGES

nginx-1.7.4 pgp

第一步：解压

tar -zxvf nginx-1.7.4.tar.gz

第二步：进入nginx-1.7.4，执行./configure 命令
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

[root@localhost nginx-1.7.4]# ./configure

checking for OS

+ Linux 2.6.32-431.el6.x86_64 x86_64

checking for C compiler ... not found

./configure: error: C compiler cc is not found

出现这个错误。

那么就是gcc 包没有安装。安装gcc 吧，骚年。

yum -y install gcc

--------------------------------------------------------------------------

再次执行./configure

./configure: error: the HTTP rewrite module requires the PCRE library.

You can either disable the module by using --without-http_rewrite_module

option, or install the PCRE library into the system, or build the PCRE library

statically from the source with nginx by using --with-pcre=<path> option.

yum install pcre-devel

------------------------------------------------------
再次执行./configure

./configure: error: the HTTP gzip module requires the zlib library.

You can either disable the module by using --without-http_gzip_module

option, or install the zlib library into the system, or build the zlib library

statically from the source with nginx by using --with-zlib=<path> option.

yum install zlib-devel

-------------------------------------------

再次执行./configure

Configuration summary

+ using system PCRE library

+ OpenSSL library is not used

+ using builtin md5 code

+ sha1 library is not found

+ using system zlib library

OK，现在可以执行make 了。
如果你想使用openssl 功能，sha1 功能。
那么安装openssl ，sha1 吧，骚年。
安装openssl
yum install openssl openssl-devel
安装sha1

yum install perl-Digest-SHA1.x86_64

开启ssl 模块 执行./configure --with-http_ssl_module
启用“server+status"页，执行./configure --with-http_stub_status_module
两个都启动，不用我说了。执行./configure --with-http_stub_status_module --with-http_ssl_module
-------------------------------------------
那么configre 就通过了。

-------------------------------------------
执行make 命令
执行make install 命令
至此，nginx 执行成功了

-------------------------------------------

下来配置环境变量
在/etc/profile 中加入：
export NGINX_HOME=/usr/local/nginx

export PATH=$PATH:$NGINX_HOME/sbin
保存，
执行 source /etc/profile ，使配置文件生效。
执行nginx -v,就能看到版本了，说明nginx 安装成功了

然后配置反向代理服务器
修改nginx/conf目录下的nginx.conf为

#user nobody;

worker_processes 1;

#error_log logs/error.log;

#error_log logs/error.log notice;

#error_log logs/error.log info;

#pid logs/nginx.pid;

}
