部署Nginx
一，安装nginx依赖: 查看是否已经安装 rpm -qa |grep gcc rpm -qa |grep openssl-devel rpm -qa |grep pcre-devel rpm -qa |grep zib-devel 安装： yum -y install 上面的依赖 二，安装nginx ./configuration make make install Configuration summary + using system PCRE library + OpenSSL library is not used + md5: using system crypto library + sha1: using system crypto library + using system zlib library nginx path prefix: "/usr/local/nginx" nginx binary file: "/usr/local/nginx/sbin/nginx" nginx configuration prefix: "/usr/local/nginx/conf" nginx configuration file: "/usr/local/nginx/conf/nginx.conf" nginx pid file: "/usr/local/nginx/logs/nginx.pid" nginx error log file: "/usr/local/nginx/logs/error.log" nginx http access log file: "/usr/local/nginx/logs/access.log" nginx http client request body temporary files: "client_body_temp" nginx http proxy temporary files: "proxy_temp" nginx http fastcgi temporary files: "fastcgi_temp" nginx http uwsgi temporary files: "uwsgi_temp" nginx http scgi temporary files: "scgi_temp" /usr/local/nginx/conf/ 上传已经配置好的proxy.conf&&nginx.conf

红色表示需要根据实际修改的地方！
