Change the tomcat internal default log mode to log4j unsuccessful records

Official: https://tomcat.apache.org/download-70.cgi

Download is the zip version: Apache-tomcat-7.0.69.zip

Follow the official documentation:
Https://tomcat.apache.org/tomcat-7.0-doc/logging.html

2. The new file is called log4j.properties , the content is not (copy of the official website) into the $CATALINA_BASE/lib next.
4. Download log4j, Required v1.2.x ,: https://logging.apache.org/log4j/1.2/download.html, download the zip version log4j-1.2.17.zip. Extract the Log4j-1.2.17.jar.
6. Download tomcat-juli.jar and tomcat-juli-adapters.jar . See the Add-ons documentation, as in the previous download of Tomcat. Just Extrax under the mark.
8. Put it and put it in log4j.jar tomcat-juli-adapters.jar $CATALINA_HOME/lib .
10. tomcat-juli.jarReplace with $CATALINA_HOME/bin/tomcat-juli.jar .
12. Delete $CATALINA_BASE/conf/logging.properties java.util.logging to avoid generating 0-length log files.

14. Start Tomcat.

    However, after pressing the above, it does not print the log properly. Show:

    Log4j:warn No Appenders could is found for logger (Org.apache.catalina.startup.Catalina).
    Log4j:warn Initialize the log4j system properly.
    Log4j:warn See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Logs folder, there are five more log files. Two have content: catalina.out , localhost . Catalina.out is the above words.
LocalHost is the record of contextinitialized.

When I renamed the log4j.properties above and started Tomcat, there was only one file in logs. The content is empty.

Note that Log4j.properties still works.

But the log cannot be lost.
