1、开发环境代理服务器安装和配置1 环境安装1.1 条件1 操作系统:centos 5.4 64 位( 或者更高的版本)。2 ssh 连接工具:putty 。3 文件传输工具：winscp1.2 服务器软件1.nginx 1.4.11.3 安装步骤1)把 nginx 安装包 nginx-1.4.1.tar.gz、pcre-8.32.tar.gz 上传到指定的安装目录，并同时对两个文件进行解压2）安装脚本yum -y install gcc gcc-c+ openssl openssl-develcd nginx-1.4.1./configure -prefix=/usr/local/nginx -

4、.4 注意事项1. 安装的服务器必须是可以出公网,否则依赖包无法安装2. 安装完后加入开机启动3. 启动命令: /usr/local/nginx/sbin/nginx 4. 重启命令: killall -9 nginx worker_processes 8;error_log /usr/local/nginx/logs/nginx_error.log crit;pid /usr/local/nginx/nginx.pid;#Specifies the value for maximum file descriptors that can be opened by this process.wo
