nginx的基本配置大致就是这样,如果绑定多个域名(不管是一级域名还是二级域名),需配置多个server,你会发现这几个server配置都差不多,主要是更改server_name及proxy_pass指向即可。upstream节点其实就是代理服务的访问路径。
如果此时访问域名,你会发现nginx的配置生效了,只是目前显示的是tomcat的默认界面。nginx的配置基本就这样了,接下来对tomcat做些配置的修改。找到tomcat里的conf/server.xml,注释掉默认的Host配置,添加如下Host配置:
<Host name="localhost" appBase="E:\tomcat\apache-tomcat-8.0.35-8082\webapps\web" deployOnStartup ="false" autoDeploy="false" unpackWARs="true">
<Context path="/" docBase="E:\tomcat\apache-tomcat-8.0.35-8082\webapps\web" />
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs" prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
以上是windows服务器下的配置,如为linux,只需更改appBase和docBase,指向项目的路径。tomcat的配置也已经完成,重启tomcat,访问域名就指向了tomcat里的项目。

//Nginx同一个域名配置多个项目

1.nginx按不同的目录分发给不同的项目:
server {

listen 80;

server_name example.com;


location ^~ /project1 {

proxy_pass http://localhost:8081;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

location ^~ /project2 {

proxy_pass http://localhost:8082;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}


location / {

proxy_pass http://localhost:8080;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

}

这里配置了三个项目:

http://example.com/project1路径分发到http://localhost:8081
http://example.com/project2路径分发到http://localhost:8082

其他路径分发到http://localhost:8080

2.启用二级域名,不同的项目分配不同的二级域名

server {

listen 80;

server_name example.com;

location / {

proxy_pass http://localhost:8080;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

}

project1

server {

listen 80;

server_name project1.example.com;

location / {

proxy_pass http://localhost:8081;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

}

project2

server {

listen 80;

server_name project2.example.com;

location / {

proxy_pass http://localhost:8082;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

}

注意:这三个项目属于不同的域名,项目之间通过http访问会存在跨域问题。
