java 开源博客 solo 实现 linux 服务器通过 nginx 安装并且实现域名转发

首先说说想要实现的效果,我有一个项目部署在服务器的 tomcat 上,假如我服务器的公网 ip 为 40.12.12.12 ,
我项目名称是 solo ,我还有一个域名是 javaweb.55555.io
那么,我想实现通过 javaweb.55555.io 就能访问到我的项目,要怎么实现呢
首先是将域名解析到公网 ip 上,这个自行百度,我是用的花生壳,然后就是剩下的两种方式

• 第一种方式:修改 tomcat

  * 将tomcat的server.xml中的端口修改为80
  
  ```
  <Connector port="80" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" />
  
  ```
  
  * 在<Host>标签中添加你自己的项目
  
  ```
  <Host name="localhost"  appBase="webapps"
        unpackWARs="true" autoDeploy="true">
  
    <Context path="" docBase="solo" reloadable="true" />
    <!-- SingleSignOn valve, share authentication between web applications
         Documentation at: /docs/config/valve.html -->
    <!--
    <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
    -->
  
    <!-- Access log processes all example.
         Documentation at: /docs/config/valve.html
         Note: The pattern used is equivalent to using pattern="common" -->
    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
           prefix="localhost_access_log" suffix=".txt"
           pattern="%h %l %u %t &quot;%r&quot; %s %b" />
  
  </Host>
  ```
  其中的 ```<Context>``` 标签就是你要进行处理的,将path设成空字符串即可
  

• 第二种方式 利用 nginx 实现转发

  • 首先是安装 nginx,可以参考 Centos 安装 nginx ,这里不再赘述
    不过要强调一点,如果之前 tomcat 占用了 80 端口,启动 nginx 会报错 端口已被占用 或者类似 # 98: Address already in use
    你需要把 tomcat 端口改回 8080 或者随意什么值,因为默认安装 nginx 配置的是 80 端口

  • 好了下面是 最重要的 nginx 配置

user root;
#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    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;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  javaweb.55555.io;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass http://localhost:8080/;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
		error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;
	#    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}
	  

上面是完整的配置文件,最主的配置在这里

	server {
        listen       80;
        server_name  javaweb.55555.io;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass http://localhost:8080/;
        }

当外网访问域名 javaweb.55555.io 时,其实访问的是公网的 80 端口,此时 nginx 监听到了这个端口,
则会将这个请求转到 http://localhost:8080/ 上,那么我们的目的就实现了
同样的 tomcat 里同样需要 <Context path="" docBase="solo" reloadable="true" /> 配置,
否则就会以这个 javaweb.55555.io/solo 网址访问
如果是 solo 这个开源项目别忘了在 latke.properties 中进行如下配置

# Browser visit protocol
 serverScheme=http
 # Browser visit domain name
 serverHost=javaweb.55555.io
 # Browser visit port, 80 as usual, THIS IS NOT SERVER LISTEN PORT!
 serverPort=
