Tomcat关闭日志输出

一般在部署Tomcat后，运行久了，catalina.out文件会越来越大，对系统的稳定造成了一定的影响。
可通过修改conf/logging.properties日志配置文件，conf/service.xml配置文件，bin/catalina.sh文件来屏蔽掉这部分的日志信息。

步骤：
1、直接修改catalina.sh文件的输出语句

原内容：
 if [ -z "$CATALINA_OUT" ] ; then  
　　CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out
修改后内容：
 if [ -z "$CATALINA_OUT" ] ; then  
    CATALINA_OUT=/dev/null  
    
2、修改conf/logging.properties日志配置文件来屏蔽掉这部分的日志信息
将level级别设置成WARNING就可以大量减少日志的输出，
当然也可以设置成OFF，直接禁用掉。

修改为OFF的部分：
1catalina.org.apache.juli.FileHandler.level = OFF
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.prefix = catalina.

2localhost.org.apache.juli.FileHandler.level = OFF
2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
2localhost.org.apache.juli.FileHandler.prefix = localhost.

3manager.org.apache.juli.FileHandler.level = OFF
3manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
3manager.org.apache.juli.FileHandler.prefix = manager.

4host-manager.org.apache.juli.FileHandler.level = OFF
4host-manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
4host-manager.org.apache.juli.FileHandler.prefix = host-manager.

java.util.logging.ConsoleHandler.level = OFF
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = OFF
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].level = OFF
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].handlers = 3manager.org.apache.juli.FileHandler

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].level = OFF
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].handlers = 4host-manager.org.apache.juli.FileHandler

这里设置为OFF
3、关闭localhost_access_log日志
修改在tomcat的安装目录conf文件夹下server.xml里配置，将AccessLogValve注释掉

原内容:
<!-- 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" />
        
修改后内容：
<!-- 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" />
        -->


通过上述3步的设置，tomcat 日志不会再输出，尤其是 catalina.out 没有了。
