讓 Tomcat 獨立輸出各個 virtual host 的 catalina.out 檔案

以下測試環境為 RHEL5、tomcat 6.0.39

一、swallowOutput設定

官網說明

If the value of this flag is true, the bytes output to System.out and System.err by the web application will be redirected to the web application logger. If not specified, the default value of the flag is false.

設定 tomcat/conf/context.cml

<Context swallowOutput="true">

……………………………………

</Context>

二、第一種方法，設定 log4j

1.      在 tomcat/lib/ 下建立 log4j.properties，以下為範例檔

##############################################################

#定義logger,名字這邊可自訂,第一個為輸出層級，為了讓log分開輸出，這邊只定義輸出層級

log4j.rootLogger=INFO, CATALINA

#定義每個appender的路徑與作用,名稱為剛定義的logger,參數請參考log4j官方文件

log4j.appender.CATALINA=org.apache.log4j.FileAppender

log4j.appender.CATALINA.File=${catalina.base}/logs/catalina.out

log4j.appender.CATALINA.Append=true

log4j.appender.CATALINA.Encoding=UTF-8

log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayout

log4j.appender.CATALINA.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

log4j.appender.S=org.apache.log4j.FileAppender

log4j.appender.S.File=${catalina.base}/logs/webapps1.out

log4j.appender.S.Append=true

log4j.appender.S.Encoding=UTF-8

log4j.appender.S.layout = org.apache.log4j.PatternLayout

log4j.appender.S.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

log4j.appender.R=org.apache.log4j.FileAppender

log4j.appender.R.File=${catalina.base}/logs/webapps2.out

log4j.appender.R.Append=true

log4j.appender.R.Encoding=UTF-8

log4j.appender.R.layout = org.apache.log4j.PatternLayout

log4j.appender.R.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost]=INFO, S

log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[jacky.com]=INFO, R

#設定tocmat host綁定logger, hosts為tomcat server.xml 內host名稱,

#這邊為 localhost綁定CATALINA logger名稱, jacky.com 綁定 R logger名稱

log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost]=INFO,S

log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[jacky.com]=INFO,R

2.      下載 log4j ，將log4j-1.2.17.jar 放到 tomcat/lib/ 內

http://logging.apache.org/log4j/1.2/download.html

3.      下載 tomcat-juli.jar 、 tomcat-juli-adapters.jar放到 tomcat/lib/ 內

http://apache.cdpa.nsysu.edu.tw/tomcat/tomcat-7/v7.0.52/bin/extras/tomcat-juli.jar

http://apache.cdpa.nsysu.edu.tw/tomcat/tomcat-7/v7.0.52/bin/extras/tomcat-juli-adapters.jar

4.      設定全域log4j

將剛下載的tomcat-juli.jar 取代 tomcat/bin/tomcat-juli.jar

5.      刪除 tomcat/conf/logging.properties 避免內建java.util.logging 產生log

6.      啟動tomcat

三、第二種方法，利用tomcat 內建logging.properties

1. 修改 tomcat/conf/logging.properties

####################################################################

#建立handlers,前綴名可自訂,但前面一定是數字開頭,

handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3jacky.org.apache.juli.FileHandler

.handlers = 1catalina.org.apache.juli.FileHandler

#設定每個handlers 層級與路徑

1catalina.org.apache.juli.FileHandler.level = FINE

1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs

1catalina.org.apache.juli.FileHandler.rotatable = false

1catalina.org.apache.juli.FileHandler.prefix = catalina

1catalina.org.apache.juli.FileHandler.suffix = .out

2localhost.org.apache.juli.FileHandler.level = FINE

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

2localhost.org.apache.juli.FileHandler.rotatable = false

2localhost.org.apache.juli.FileHandler.prefix = webapps1

2localhost.org.apache.juli.FileHandler.suffix = .out

3jacky.org.apache.juli.FileHandler.level = FINE

3jacky.org.apache.juli.FileHandler.directory = ${catalina.base}/logs

3jacky.org.apache.juli.FileHandler.rotatable = false

3jacky.org.apache.juli.FileHandler.prefix = webapps2

3jacky.org.apache.juli.FileHandler.suffix = .out

#綁定handler到 tomcat host

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO

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

org.apache.catalina.core.ContainerBase.[Catalina].[jacky.com].level = INFO

org.apache.catalina.core.ContainerBase.[Catalina].[jacky.com].handlers = 3jacky.org.apache.juli.FileHandler

2. tomcat啟動會讀tomcat/conf/logging.properties設定，如果檔案不可讀或未設定，則預設變為$JAVA_HOME/lib/logging.properties

3. tocmat 會從 tomcat/bin/startup.sh 起動catalina.sh，所以java參數及變數要寫在tomcat/bin/catalina.sh，啟動才會生效
