orzdba_monitor.sh脚本使用

1.orzdba_monitor.sh脚本使用

• ./orzdba_monitor.sh 主要是用nohup同时在后台调用orzdba，启动下面三个命令

[root@node02 scripts]# ps -ef |grep orzdba
root     19887     1  0 17:40 ?        00:00:00 /usr/bin/perl -w /scripts/orzdba -i 10 -t -mysql -innodb_rows -L /r2/monitor/log_orzdba_mysql -logfile_by_day
root     19888     1  0 17:40 ?        00:00:00 /usr/bin/perl -w /scripts/orzdba -i 10 -t -sys -d sda -L /r2/monitor/log_orzdba_sys -logfile_by_day
root     19889     1  0 17:40 ?        00:00:00 /usr/bin/perl -w /scripts/orzdba -i 10 -processlist -L /r2/monitor/log_orzdba_proc -logfile_by_day

• 根据实际情况，需要修改变量：

  • SCRIPTS_FILE=/scripts --脚本所在目录
  • MONITOR=/r2/monitor --监控日志保存目录
  • DEVICE_NAME="sda" --数据库所在的硬盘盘符
  • DELETE_DAYS=15 --日志保存天数

• 添加权限

[root@node02 scripts]# chmod 755 orzdba
[root@node02 scripts]# chmod 755 orzdba_monitor.sh

• 计划任务

  • crontab -e
  • 每5分钟执行一次脚本，如果没有进程就启动
  • */5 * * * * /scripts/orzdba_monitor.sh >/dev/null 2>&1

• 日志，分别生成三个日志，根据日期截断日志，可以设置保存日志的天数

  • 日志目录显示如下：

[root@node01 monitor]# ll /r2/monitor/
total 194052
-rw-r--r-- 1 root root    225257 Apr 24 15:36 log_orzdba_mysql.2018-04-24
-rw-r--r-- 1 root root 180040747 Apr 24 15:36 log_orzdba_proc.2018-04-24
-rw-r--r-- 1 root root    202990 Apr 24 15:36 log_orzdba_sys.2018-04-24
-rw-r--r-- 1 root root       114 Apr 24 15:35 orzdba.log

2.orzdba

• 根据实际情况，在orzdba中修改帐号信息。

my $user="root";       # -u   --mysql帐号
my $pass="iforgot";    # -p   --mysql密码
my $host="localhost";  # -h   --mysqlhost

• 验证帐号如下：

[root@node02 scripts]#  ./orzdba -u root -p iforgot -h localhost -innodb  -C 5 -i 2  2>/dev/null

3.问题

1.没有创建监控目录，请排查脚本执行权限

2.监控目录里面没有获取到日志文件，请排查MySQL访问权限或者监控盘符配置错误

3.报"orzdba_xxxx未启动,开始执行",但没获取到日志，请排查是否有已启动的线程，kill掉，重新执行
