Tomcat服务器
不同端口 不同域名 不同网站
- 服务器：阿里的
- 系统:Ubuntu 16.04
- Tomcat版本： Apache Tomcat/8.5.42
- 软件：WinSCP、petty.exe
原来根据哔哩哔哩教程：设置了一个网站，用www.a.com访问。现在想增加www.b.com访问另一个网站。
参考网上的教程找到tomcat安装的路径，修改tomcat/conf/server.xml，一顿操作，发现没有用。
于是自己研究了一下,弄好了。
serve.xml(旧)
删了注释的

细心的你可以发现：
只有Host里面的东西改了一下。新增或修改的内容如下：
<Host name="www.a.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<!-- <Context docBase="app1" path="/app1" reloadable="true" /> -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs/1"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
<Host name="www.b.com" appBase="webapps2"
unpackWARs="true" autoDeploy="true">
<!-- <Context docBase="app2" path="" reloadable="true" /> -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs/2"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
里面多了一个webapps2，我们要在tomcat目录下把原来的webapps复制一下，改名成为webapps2,就行。
然后要用命令重启tomcat:看这个教程
关闭tomcat,测试一下，是无法访问自己网站的。
之后就能通过不同网址访问不同网站了。记得阿里云控制台要把你要用的端口开放。
其他问题
但是有一个小bug。访问网址如果没有 www，就会访问不到。
尝试1：
于是我做做出如下修改：（去掉www）
<Host name="a.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<!-- <Context docBase="app1" path="/app1" reloadable="true" /> -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs/1"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
<Host name="b.com" appBase="webapps2"
unpackWARs="true" autoDeploy="true">
<!-- <Context docBase="app2" path="" reloadable="true" /> -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs/2"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
然后要用命令重启tomcat，但是发现，网址加上www话就无法访问了。真是两者不可得兼。
尝试2：
最后对xml不熟悉的我，用了如下麻烦的方法：
<Host name="a.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<!-- <Context docBase="app1" path="/app1" reloadable="true" /> -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs/1"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
<Host name="www.a.com" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<!-- <Context docBase="app1" path="/app1" reloadable="true" /> -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs/1"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
<Host name="b.com" appBase="webapps2"
unpackWARs="true" autoDeploy="true">
<!-- <Context docBase="app2" path="" reloadable="true" /> -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs/2"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
<Host name="www.b.com" appBase="webapps2"
unpackWARs="true" autoDeploy="true">
<!-- <Context docBase="app2" path="" reloadable="true" /> -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs/2"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
</Host>
简单粗暴，这样子两个方式都能访问了。
如果大家有简单的方法，可以留言，教教小编，多谢。
