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.gz
  
    2. 解压缩
        tar zxvf cronolog-1.6.2.tar.gz
  
    3. 进入安装目录
        cd cronolog-1.6.2
  
    4. 运行安装
        ./configure
        make
        make install
  
    5. 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" ] ; then
    if [ $have_tty -eq 1 ]; then
      echo "Using Security Manager"
    fi
    shift
    eval $_NOHUP "\"$_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 &

  else
    eval $_NOHUP "\"$_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

1. 创建shell脚本：

    vim del-15-days-ago-logs.sh
   

2. 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 {} \;
   

3. 分配可运行权限：

    chmod +x del-15-days-ago-logs.sh
   

4. 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)
   

5. 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.text
    touch -d "30 days ago" test.log
    .......
   
    然后等待计划任务执行吧。看看效果！！！

# -----------------------------------------------------------------------------
# Control Script for the CATALINA Server
#
# Environment Variable Prerequisites
#
#   Do not set the variables in this script. Instead put them into a script
#   setenv.sh in CATALINA_BASE/bin to keep your customizations separate.
#
#   CATALINA_HOME   May point at your Catalina "build" directory.
#
#   CATALINA_BASE   (Optional) Base directory for resolving dynamic portions
#                   of a Catalina installation.  If not present, resolves to
#                   the same directory that CATALINA_HOME points to.
#
#   CATALINA_OUT    (Optional) Full path to a file where stdout and stderr
#                   will be redirected.
#                   Default is $CATALINA_BASE/logs/catalina.out
#
#   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
#                   "run" or "debug" command is executed.
#                   Include here and not in JAVA_OPTS all options, that should
#                   only be used by Tomcat itself, not by the stop process,
#                   the version command etc.
#                   Examples are heap size, GC logging, JMX ports etc.
#
#   CATALINA_TMPDIR (Optional) Directory path location of temporary directory
#                   the JVM should use (java.io.tmpdir).  Defaults to
#                   $CATALINA_BASE/temp.
#
#   JAVA_HOME       Must point at your Java Development Kit installation.
#                   Required to run the with the "debug" argument.
#
#   JRE_HOME        Must point at your Java Runtime installation.
#                   Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME
#                   are both set, JRE_HOME is used.
#
#   JAVA_OPTS       (Optional) Java runtime options used when any command
#                   is executed.
#                   Include here and not in CATALINA_OPTS all options, that
#                   should be used by Tomcat and also by the stop process,
#                   the version command etc.
#                   Most options should go into CATALINA_OPTS.
#
#   JPDA_TRANSPORT  (Optional) JPDA transport used when the "jpda start"
#                   command is executed. The default is "dt_socket".
#
#   JPDA_ADDRESS    (Optional) Java runtime options used when the "jpda start"
#                   command is executed. The default is localhost:8000.
#
#   JPDA_SUSPEND    (Optional) Java runtime options used when the "jpda start"
#                   command is executed. Specifies whether JVM should suspend
#                   execution immediately after startup. Default is "n".
#
#   JPDA_OPTS       (Optional) Java runtime options used when the "jpda start"
#                   command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,
#                   and JPDA_SUSPEND are ignored. Thus, all required jpda
#                   options MUST be specified. The default is:
#
#                   -agentlib:jdwp=transport=$JPDA_TRANSPORT,
#                       address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND

#                   of the catalina startup java process, when start (fork) is
#                   used
#
#   LOGGING_CONFIG  (Optional) Override Tomcat's logging config file
#                   Example (all one line)

#
#   UMASK           (Optional) Override Tomcat's default UMASK of 0027
#
#   USE_NOHUP       (Optional) If set to the string true the start command will
#                   use nohup so that the Tomcat process will ignore any hangup
#                   signals. Default is "false" unless running on HP-UX in which
#                   case the default is "true"
