nginx安装配置

1. 安装 nginx 服务：
   wget http://nginx.org/download/nginx-1.9.5.tar.gz
   tar -zxvf nginx-1.5.9.tar.gz
   cd nginx-1.5.9
   mkdir /user/local/nginx159
   ./configure –prefix=/usr/local/nginx159
   报错执行：./configure –prefix=/usr/local/nginx159 –conf-path=/usr/local/nginx159/nginx.conf
   make && make install
2. nginx 使用
   1. 检查是否安装成功：
   cd /usr/local/nginx159/sbin
   ./nginx -t 出现 is ok 和 test is successful 就算OK 了
   2. 启动：./nginx
   3. 停止：./nginx -s stop
   4. 重启：./nginx -s reload
   或者：重新加载配置文件：./nginx -c /usr/local/nginx/conf.d/nginx_http_auth_es.conf -s reload
   5. 修改了配置文件后最好先检查一下修改过的配置文件是否正确：/usr/nginx/sbin/nginx -t
   6. 页面方式检查是否安装成功
   1. 打开端口: 80
   打开 8080 端口：# /sbin/iptables -I INPUT -p tcp –dport 80 -j ACCEPT
   2. 然后在保存操作：# /etc/rc.d/init.d/iptables save
   3. 查看打开的端口：# /etc/init.d/iptables status
3. 设置开机启动
   
   1. 写开机启动脚本：vi nginx 脚本如下，其中红框部分为必须
   2. 放在 /etc/init.d/ 目录下
   3. 给予执行权限：$ chmod 755 nginx
   4. chkconfig –add nginx
   5. chkconfig nginx on
      代码如下：

## chkconfig: - 90 80# description: xxx start/stop/reloadcase "$1" instart)        /usr/local/nginx1119/sbin/nginx -c /usr/local/nginx1119/conf/nginx.conf ;;stop)        /usr/local/nginx1119/sbin/nginx -s stop;;restart)        /usr/local/nginx1119/sbin/nginx restart ;;esac

1. nginx收集访问日志
   vim nginx_log.conf

include       mime.types;    default_type  application/octet-stream;    #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;    log_format main_json '{"createdTime":"$time_local",'                        '"nginxIP":"$server_addr",'                        '"serverIP":"$upstream_addr",'                        '"clientIP":"$remote_addr",'                        '"realClientIP":"$http_x_forwarded_for",'                        '"req_host":"$http_host",'                        '"req_url":"$uri",'                        '"req_method":"$request_method",'                        '"req_remoteUser":"$remote_user",'                        '"req_sessionID":"$cookie_jsessionid",'                        '"req_accessToken":"$http_accesstoken",'                        '"req_referer":"$http_referer",'                        '"req_body":"$request_body",'                        #'"req_body":"-",'                        '"req_length":$request_length,'                        '"req_userAgent":"$http_user_agent",'                        '"request":"$request",'                        '"res_BytesNoHead":$body_bytes_sent,'                        '"res_Bytes":$bytes_sent,'                        '"res_Body":"-",'                        '"connectionID":"$connection",'                        '"connectionID_num":$connection_requests,'                        '"status":$status,'                        '"useTime":$request_time}';    access_log  logs/access.log  main_json;

1. 如果要获取自定义header里的参数，操作如下：
   修改配置文件fastcgi.conf,加上以下内容
   # vi conf/fastcgi.conf
   添加如下：fastcgi_param HTTP_ACCESSTOKEN $http_accesstoken;
   ngxin日志里添加：‘“accessToken”: “http_accesstoken”, ’
