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
