tomcat 日志分割

用 cronolog 分割 tomcat 的 catalina.out 文件。cronolog 官网地址

编译安装 cronolog

shell

wget https://files.cnblogs.com/files/crazyzero/cronolog-1.6.2.tar.gz
tar zxvf cronolog-1.6.2.tar.gz 
cd cronolog-1.6.2
./configure 
make && make install

查看 cronolog 安装后所在目录（验证安装是否成功）
shell
```
which cronolog
一般情况下显示为：/usr/local/sbin/cronolog
```

编辑 tomcat 目录 bin 下的 catalina.sh 文件, 找到下面这行，类似这样的行有 2 处：

# 修改前
org.apache.catalina.startup.Bootstrap "$@" start \
      >> "$CATALINA_OUT" 2>&1 &
# 修改后
org.apache.catalina.startup.Bootstrap "$@" start \
2>&1 | /usr/local/sbin/cronolog /usr/local/tomcat/logs/icatalina.%Y-%m-%d.out >>/dev/null &

注释此行：touch “$CATALINA_OUT "，如果不好使就把整个 if 注释掉，如下图为修改后的结果

# 以下大概是 tomcat 目录 bin 下的 catalina.sh 文件的第 470 行的数据，修改后的结果
 shift
  #if [ -z "$CATALINA_OUT_CMD " ] ; then
  #  touch "$CATALINA_OUT "
  #else
  #  if [ ! -e "$CATALINA_OUT " ]; then
  #    if ! mkfifo "$CATALINA_OUT "; then
  #      echo " cannot create named pipe $CATALINA_OUT. Start aborted."
  #      exit 1
  #    fi
  #  elif [ ! -p "$CATALINA_OUT " ]; then
  #    echo "$CATALINA_OUT exists and is not a named pipe. Start aborted."
  #    exit 1
  #  fi
  #  $CATALINA_OUT_CMD <"$ CATALINA_OUT " &
  #fi
  if [ "$1" = "-security" ] ; then
    if [ $have_tty -eq 1 ]; then
      echo "Using Security Manager"
    fi
    shift
    eval $_NOHUP "\"$_RUNJAVA\"" "\"$CATALINA_LOGGING_CONFIG\"" $LOGGING_MANAGER "$JAVA_OPTS" "$CATALINA_OPTS" \
      -D$ENDORSED_PROP="\"$JAVA_ENDORSED_DIRS\"" \
      -classpath "\"$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_OUT" >> /dev/null &

  else
    eval $_NOHUP "\"$_RUNJAVA\"" "\"$CATALINA_LOGGING_CONFIG\"" $LOGGING_MANAGER "$JAVA_OPTS" "$CATALINA_OPTS" \
      -D$ENDORSED_PROP="\"$JAVA_ENDORSED_DIRS\"" \
      -classpath "\"$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_OUT" >> /dev/null &

  fi

然后重启 tomcat，查看日志结果。
