生成catalina.out方法

导语：本文为Windows下生tomcat将控制台信息输出到catalina.out文件  且 保证能实时查看日志文件的方法。

一、创建catalina.out

1、修改tomcat bin目录下的startup.bat文件

修改位置：在startup.bat文件倒数第二行

修改call "%EXECUTABLE%" start%CMD_LINE_ARGS%

为：call "%EXECUTABLE%" run %CMD_LINE_ARGS%

2、修改catalina.bat文件

修改位置：catalina.bat文件最后几行

修改为（修改处已用红色标记）：

rem Execute Java with the applicable properties

if not "%JPDA%" == "" goto doJpda

if not "%SECURITY_POLICY_FILE%" == "" goto doSecurity

%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %DEBUG_OPTS% -Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%" -Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%" -Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION% >> "%CATALINA_BASE%"\logs\catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out

goto end

:doSecurity

%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %DEBUG_OPTS% -Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%" -Djava.security.manager -Djava.security.policy=="%SECURITY_POLICY_FILE%" -Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%" -Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION% >> "%CATALINA_BASE%"\logs\catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out

goto end

:doJpda

if not "%SECURITY_POLICY_FILE%" == "" goto doSecurityJpda

%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %JPDA_OPTS% %DEBUG_OPTS% -Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%" -Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%" -Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION% >> "%CATALINA_BASE%"\logs\catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out

goto end

:doSecurityJpda

%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %JPDA_OPTS% %DEBUG_OPTS% -Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%" -Djava.security.manager -Djava.security.policy=="%SECURITY_POLICY_FILE%" -Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%" -Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION%

>>"%CATALINA_BASE%"\logs\catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out

goto end

:end

3、启动startup.bat文件  查看tomcat logs目录下是否存在catalina.out文件

二、如何实时查看catalina.out文件？

1、安装rktools.exe文件   记录安装路径

2、将rktools.exe安装路径添加PATH环境变量中

在cmd下tail /?，出现以下信息则说明安装成功了：

3、在tomcat bin 目录下新增tomcat_s1log.bat文件（文件名可以自行定义），内容如下：

@echo off

if not exist  "%CATALINA_BASE%"\logs\catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out echo "" >  "%CATALINA_BASE%"\logs\catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out

tail -f  "%CATALINA_BASE%"\logs\catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out

4、修改catalina.bat文件

185行：echo Using JRE_HOME:        "%JRE_HOME%"

goto java_dir_displayed

:use_jdk

echo Using JAVA_HOME:       "%JAVA_HOME%"

:java_dir_displayed

echo Using CLASSPATH:       "%CLASSPATH%"

修改为：

echo Using JRE_HOME:        "%JRE_HOME%"

tomcat_s1log.bat

goto java_dir_displayed

:use_jdk

echo Using JAVA_HOME:       "%JAVA_HOME%"

:java_dir_displayed

echo Using CLASSPATH:       "%CLASSPATH%"

5、启动startup.bat 会看到两个控制台 一个启动信息界面 一个实时日志监控界面

（注：如果想把tomcat_s1log.bat放在桌面启动 则需要修改tomcat_s1log.bat

里面的"%CATALINA_BASE%"修改为对应的tomcat目录。）

例：

d:

cd D:\\Program Files\\apache-tomcat-7.0.5\\logs

if not exist  catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out echo "" >  catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out

tail -f  catalina_%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%.out
