default root uri

例如我需要访问 http://localhost/ 的时候，希望它会去 /webapps/exampls/

更改root app的方法

  • 首先当然是看看ps，弄清楚到底是采用哪个$catalina.home

  • 在gentoo的tomcat7中，需要的设置/etc/tomcat-7/Catalina/localhost/ROOT.xml，根据的是这个

$ sudo cat /etc/tomcat-7/Catalina/localhost/ROOT.xml
<?xml version="1.0" encoding="UTF-8"?>
<Context docBase="${catalina.home}/webapps/examples" />

那么，curl localhost/ 的时候，就是读取 ”${catalina.home}/webapps/examples”。

install

  • 查看tomcat目录的RUNNING.txt。
  • install jre ，其实可以直接下载JRE，解压即可，不必设置环境。
  • install Apache Tomcat， 解压即可。
  • 设置${CATALINA_HOME}/bin/setenv.sh设置 JRE_HOME , CATALINA_HOME
$ cat /usr/local/tomcat1/bin/setenv.sh 
#!/bin/bash - 
JRE_HOME=/opt/jre1.7.0_21
CATALINA_HOME=/opt/apache-tomcat-7.0.56

Multiple Tomcat Instances

在gentoo的 /usr/share/tomcat-7/gentoo/tomcat-instance-manager.bash 中，可以直接创建instances，根据这个方法和刚刚的RUNNING.txt，可以得到方法如下：

  • 拷贝相应的文件夹到$CATALINA_BASE处， conf,temp,logs,webapps,work,bin
  • 修改 ${CATALINA_BASE}/bin/setenv.sh ，在这里除了JRE_HOME, CATALINA_HOME，还需要CATALINA_BASE
  • 修改 ${CATALINA_BASE}/conf/server.xml ，　主要是修改有关端口的设置，一般包括server, http connector, AJP 等。
  • 最好设置一下 ${CATALINA_BASE}/webapps/ROOT 到相应的app即可
$ cat /usr/local/tomcat1/bin/setenv.sh 

#!/bin/bash - 
JRE_HOME=/opt/jre1.7.0_21
CATALINA_BASE=/usr/local/tomcat2
CATALINA_HOME=/opt/apache-tomcat-7.0.56

虚拟主机(多域名绑定到同一IP)

          # name 域名  appBase 虚拟主机主程序目录  
        www.456.com                 # 其他域名
                 # war文件路径或其他程序路径
                
                # 日志设置

appBase和docBase对应的话，可以不需在url上填入模块名称。如果没设置好，则需要填入模块名称本例“/test/”。

tomcat log rotate

如下，通过修改server.xml里面的org.apache.catalina.valves.AccessLogValve, 添加fileDateFormat即可。

$ cat logformat.txt
<Valve
    className="org.apache.catalina.valves.AccessLogValve"
    directory="${catalina.base}/logs"
    prefix="access_log"
    fileDateFormat="yyyy-MM-dd.HH"
    suffix=".log"
    pattern="%t %H cookie:%{SESSIONID}c request:%{SESSIONID}r  %m %U %s %q %r"

/>

$ diff ~/tomcat-7711/conf/server.xml*
139c139
<              directory="logs"  prefix="access." fileDateFormat="yyyy-MM-dd.HH" suffix=".log"
---
>              directory="logs"  prefix="access." suffix=".log"

How to disable remote shutdown in Tomcat

  • change the port number from default to different one (not recommended)
  • change the shutdown command (partially recommended)
  • change port number to -1 (recommended)

** $CATALINA_HOME/conf/server.xml **

<Server port="8005" shutdown="SHUTDOWN">

to

<Server port="-1" shutdown="SHUTDOWN">

修改accesslog的pattern

  • 需要使用tomcat7
%{yyyy-MM-dd'T'HH:mm:ss,SSSZ}t
  • 例子一
pattern="%h %l %u %t &quot;%r&quot; %s %b %{yyyy-MM-dd'T'HH:mm:ss,SSSZ}t"
