Cronolog 分割 Tomcat8 Catalina.out日志。
默认情况下，tomcat的catalina.out日志文件是没有像其它日志一样，按日期进行分割，而是全部输出全部写入到一个catalina.out，这样日积月累就会造成.out日志越来越大，给管理造成了不便，为了实现像其它日志文件一样按日期归档，这里我采用cronolog来完成日志分割。
一、安装Cronolog
-
YUM 安装
-
yum install cronolog或者使用下载压缩包安装
-
1. 下载(最新版本)wget http://cronolog.org/download/cronolog-1.6.2.tar.gz2. 解压缩tar zxvf cronolog-1.6.2.tar.gz3. 进入安装目录cd cronolog-1.6.24. 运行安装./configuremakemake install5. 查看是否安装成功which cronolog结果：/usr/local/sbin/cronolog (这个是cronolog的安装路径,后面会用到)如果上面两种下载方式都受到网络限制,可以去自由软件库下载 http://download.chinaunix.net/download.php?id=3457&ResourceID=1851
-
二、修改Tomcat下bin/catalina.sh文件
修改要分隔的Tomcat的日志下bin/catalina.sh文件，要修改的在290行。修改前先拷贝一份。1. cp catalina.sh catalina.sh.bak 2. vim catalina.sh -c 417 或者 vim catalina.sh之后:417 (进入到catalina.sh的第417行。) 下面为需要修改的内容：标红的是要修改的区域 -
修改为：shift# touch "$CATALINA_OUT"if [ "$1" = "-security" ] ; thenif [ $have_tty -eq 1 ]; thenecho "Using Security Manager"fishifteval $_NOHUP "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \-classpath "\"$CLASSPATH\"" \-Djava.security.manager \-Djava.security.policy=="\"$CATALINA_BASE/conf/catalina.policy\"" \-Dcatalina.base="\"$CATALINA_BASE\"" \-Dcatalina.home="\"$CATALINA_HOME\"" \-Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \org.apache.catalina.startup.Bootstrap "$@" start 2>&1\| /usr/local/sbin/cronolog "$CATALINA_BASE"/logs/catalina.%Y-%m-%d.out >> /dev/null &elseeval $_NOHUP "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \-classpath "\"$CLASSPATH\"" \-Dcatalina.base="\"$CATALINA_BASE\"" \-Dcatalina.home="\"$CATALINA_HOME\"" \-Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \org.apache.catalina.startup.Bootstrap "$@" start 2>&1\| /usr/local/sbin/cronolog "$CATALINA_BASE"/logs/catalina.%Y-%m-%d.out >> /dev/null &fi修改后，重启Tomcat。可以看到更改已经生效。(看到catalina.out出现了catalina.2017-12-19.out等按照日期分类的输出文件说明配置成功)。
如果配置不成功，肯定是修改的位置不对。 本文后也附有catalina.out修改后的完整内容，直接复制粘贴，替换掉catalina.out内的内容即可。 -
三、shell利用crontab自动清除日志
linux下运行程序有时会产生大量的记录日志，以便排除隐藏很深的问题，但时间一长就会占用很多的磁盘空间。每天手动清除也比较麻烦，因此一个定时脚本执行是很有必要的。
3.1 删除文件shell命令详解
find 对应目录 -mtime +天数 -name "文件名" -exec rm -rf {} \;例子：find /opt/soft/log/ -mtime +30 -name "*.log" -exec rm -rf {} \;说明：将/opt/soft/log/目录下所有30天前带".log"的文件删除。具体参数说明如下：find：linux的查找命令，用户查找指定条件的文件；/opt/soft/log/：想要进行清理的任意目录；-mtime：标准语句写法；+30：查找30天前的文件，这里用数字代表天数；"*.log"：希望查找的数据类型，"*.jpg"表示查找扩展名为jpg的所有文件，"*"表示查找所有文件，这个可以灵活运用，举一反三；-exec：固定写法；rm -rf：强制删除文件，包括目录；{} \; ：固定写法，一对大括号+空格+\+;3.2 创建shell脚本即crontab计划任务
-
创建shell脚本：
vim del-15-days-ago-logs.sh -
脚本内输入以下内容，可以写多行，以分号分隔，同时管理多个tomcat的日志：
(这里我尝试如果加上#!/bin/sh计划任务不能生效，因此我没加。另外该脚本与计划任务内不要有注释。)find /opt/soft/log/ -mtime +30 -name "*.log" -exec rm -rf {} \; -
分配可运行权限：
chmod +x del-15-days-ago-logs.sh -
使用crontab加入到系统计划任务：
crontab -e在计划任务内输入以下内容：10 0 * * * /opt/soft/log/del-15-days-ago-logs.sh >/dev/null 2>&1(这里设置的是每天凌晨0点10分执行del-15-days-ago-logs.sh文件进行数据清理任务,根据自己需求灵活变化清理时间和脚本防止的地址) -
四、附：修改后的Catalina.out文本内容：(实在配置不正确的朋友就直接复制吧)

ps：上述操作进行完后，就可以了，这里为了方便测试，可以创建n天前创建的文件。
touch -d "30 days ago" test.texttouch -d "30 days ago" test.log.......然后等待计划任务执行吧。看看效果！！！
