1、catalina、host-manager、localhost、manager日志修改 (1)在tomcat/conf/logging.properties文件下修改“maxDays”,系统默认是90天,对于高并发大访问量的服务,将保存的天数设置为最短。 (2)将level级别设置成WARNING就可以大量减少日志的输出,一般日志的级别有: SEVERE (highest value) > WARNING > INFO > CONFIG > FINE > FINER > FINEST (lowest value),这里建议设置成“ WARNING”。 1catalina.org.apache.juli.AsyncFileHandler.level = WARNING 1catalina.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs 1catalina.org.apache.juli.AsyncFileHandler.prefix = catalina. 1catalina.org.apache.juli.AsyncFileHandler.maxDays = 90 1catalina.org.apache.juli.AsyncFileHandler.encoding = UTF-8 2localhost.org.apache.juli.AsyncFileHandler.level = WARNING 2localhost.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs 2localhost.org.apache.juli.AsyncFileHandler.prefix = localhost. 2localhost.org.apache.juli.AsyncFileHandler.maxDays = 90 2localhost.org.apache.juli.AsyncFileHandler.encoding = UTF-8 3manager.org.apache.juli.AsyncFileHandler.level = WARNING 3manager.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs 3manager.org.apache.juli.AsyncFileHandler.prefix = manager. 3manager.org.apache.juli.AsyncFileHandler.maxDays = 90 3manager.org.apache.juli.AsyncFileHandler.encoding = UTF-8 4host-manager.org.apache.juli.AsyncFileHandler.level = WARNING 4host-manager.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs 4host-manager.org.apache.juli.AsyncFileHandler.prefix = host-manager. 4host-manager.org.apache.juli.AsyncFileHandler.maxDays = 90 4host-manager.org.apache.juli.AsyncFileHandler.encoding = UTF-8 2、localhost_access_log日志禁用 在tomcat/conf/server.xml文件中注释掉“localhost_access_log”日志生成 <!-- <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> --> 3、catalina.out日志禁用 catalina.out与按天的catalina.xxxx.log重复,所以这里直接禁用。 在tomcat/bin/catalina.sh中找到下面位置 if [ -z "$CATALINA_OUT" ] ; then CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out 修改到dev/null,当路径不存在时,catalina.out日志也就被禁用 if [ -z "$CATALINA_OUT" ] ; then CATALINA_OUT="$CATALINA_BASE"/dev/null 4、清理tomcat缓存 1.进入tomcat/bin目录下,执行sh shutdown.sh命令关闭tomcat。 2.然后执行命令 ps -aux | grep tomcat 命令,查看tomcat命令是否真的关闭 3.如果没有关闭执行 kill -9 #pid 来彻底关闭tomcat(#pid是tomcat的进程ID) root 17505 0.0 0.0 63344 768 pts/1 S+ 10:22 0:00 grep tomcat USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND 4.最后进入tomcat/work目录下,执行 rm -rf Catalina 来删除缓存文件 5.执行ls 确认是否删除,如果work目录下没有Catalina文件夹说明删除成功。 6.在进入tomcat/bin目录下,执行./startup.sh命令来重启tomcat。 即停止tomcat、进入tomcat/work目录下——>执行 rm -rf Catalina 来删除缓存文件——>启动tomcat = OK (责任编辑:IT) |
