目的:搭建Nginx与tomcat整合,用Nginx代替apache
步骤:
一、安装Nginx
1、上传nginx-0.7.至/usr/local
2、执行如下命令解压nginx:
1.#cd /usr/local
2.#tar zxvf  nginx-0.7.6
3、编译安装nginx
1.#cd nginx-0.7.63
2.#./configure --with-http_stub_status_module --with-http_ssl_module  #启动server状态页和https模块
执行完后会提示一个错误,说缺少PCRE library 这个是HTTP Rewrite 模块,也即是url静态化的包
可上传pcre-7.,输入如下命令安装:
1.#tar zxvf pcre-7.
2.#cd pcre-7.9
3.#./configure
4.#make
5.#make install
安装pcre成功后,继续安装nginx
如果是ubuntu 或Debian系统请先安装
# apt-get install libpcre3 libpcre3-dev
原文:
I need to compile few application and I need Perl 5 Compatible Regular Expression Library (PCRE). Under CentOS I can use a package called pcre-devel, but Debian do not have the same. How do I install pcre-devel under Debian / Ubuntu Linux?
Perl-compatible regular expression library. PCRE has its own native API, but a set of "wrapper"
functions that are based on the POSIX API are also supplied in the library libpcreposix. Note that this just provides a POSIX calling interface to PCRE: the regular expressions themselves still follow Perl syntax and semantics. The header file for the POSIX-style functions is called pcreposix.h. To install PCRE, type thy following command:
# apt-get update
# apt-get install libpcre3 libpcre3-dev
1.#cd nginx-0.7.63
2.#./configure
3.#make
4.#make install
4、nginx安装成功后的安装目录为/usr/local/nginx
在conf文件夹中新建f,用于配置一些代理参数,内容如下:
01.#!nginx (-)
02.# f
03.proxy_redirect  off;
04.proxy_set_header    Host $host;
05.proxy_set_header    X-Real-IP $remote_addr;  #获取真实ip
06.#proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for; #获取代理者的真实ip
07.client_max_body_size  10m;
08.client_body_buffer_size 128k;
09.proxy_connect_timeout  90;
10.proxy_send_timeout  90;
11.proxy_read_timeout  90;
12.proxy_buffer_size  4k;
13.proxy_buffers        4 32k;
14.proxy_busy_buffers_size 64k;
15.proxy_temp_file_write_size 64k;
编辑安装目录下conf文件夹中的f,输入如下内容
001.#运行nginx所在的用户名和用户组
002.#user  www www;
003.
004.#启动进程数
005.worker_processes 8;
006.#全局错误日志及PID文件

5、修改/usr/local/nginx/f配置文件后,请执行以下命令检查配置文件是否正确:
1.#/usr/local/nginx/sbin/nginx -t
如果屏幕显示以下两行信息,说明配置文件正确:
1.the configuration file /usr/local/nginx/f syntax is ok
2.the configuration file /usr/local/nginx/f was tested successfully
如果提示unknown host,则可在服务器上执行:ping www.baidu如果也是同样提示unknown host则有两种可能:
a、服务器没有设置DNS服务器地址,查看/f下是否设置,若无则加上
b、防火墙拦截
6、启动nginx的命令
1.#/usr/local/nginx/sbin/nginx
这时,输入以下命令查看Nginx主进程号:
1.ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
7、停止nginx的命令
1.#/usr/local/nginx/sbin/nginx -s stop
8、在不停止Nginx服务的情况下平滑变更Nginx配置
a、修改/usr/local/nginx/f配置文件后,请执行以下命令检查配置文件是否正确:
1./usr/local/nginx/sbin/nginx -t
如果屏幕显示以下两行信息,说明配置文件正确:
1.the configuration file /usr/local/nginx/f syntax is ok
2.the configuration file /usr/local/nginx/f was tested successfully
b、这时,输入以下命令查看Nginx主进程号:
1.ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
屏幕显示的即为Nginx主进程号,例如:
6302
这时,执行以下命令即可使修改过的Nginx配置文件生效:
1.kill -HUP 6302
或者无需这么麻烦,到Nginx的Pid文件:
1.kill -HUP `cat /usr/local/nginx/nginx.pid`
9、nginx启动好后启动tomcat,此时输入主机ip地址即可看到“My web!”
三、其他
stub_status
语法: stub_status on
默认值: None
作用域: location
创建一个location 区域启用stub_status
"stub status" 模块返回的状态信息跟mathopd's 的状态信息很相似. 返回的状态信息如下:
1.Active connections: 291
2.server accepts handled requests
