tomcat split logs on top of the Centos7

When the author during the test, there are several operating practices, specific reference .

Centos7 default opened 80 ports and 22 ports.

Scenarios

tomcat7 in the actual production environment, due to the continued deployment of the project, Catalina.out file reaches the size of 2G, and each time the query logs need to check the entire file, causing it too difficult queries.

Hope: Catalina.out log files by date divide. Placed position / home / logs / tomcat7 directory. As /home/logs/tomcat7/20180807/catalina.out.

Close tomcat

Download of java

Log4j is not supported by date generated a different folder

tomcat-juli.jar 和 tomcat-juli-adapters.jar ： http://www.apache.org/dist/tomcat/tomcat-7/v7.0.90/bin/extras/

1.2.17.jar-log4j: http://www.apache.org/dist/logging/log4j/1.2.17/ (first download the zip, and unzip to find jar)

Upload jar

1. The above three jar into $ CATALINA_HOME / lib below
2. Change the $ CATALINA_HOME / bin below tomcat-juli.jar as tomcat-juli_bak.jar
3. The tomcat-juli.jar into $ CATALINA_HOME / bin directory
4. Backup $ CATALINA_HOME / conf / logging.properties file logging_bak.properties

Production Resource File

File name is: log4j.properties, and change the file uploaded to: under $ CATALINA_HOME / lib directory
