zabbix在监控mysql数据库时,会使用自带的模板Template App MySQL,是不能直接使用的,因为没有key,而获取不到数据,前端会出现如下报错“Warning: Using a password on the command line interface can be insecure.”报错原因是mysql 5.6以后的版本增加了密码安全策略,在命令行里加上密码就会强制报错,而5.6之前版本可以直接使用的。
zabbix_agentd客户端设置
1.在mysql数据上创建一个普通用户lqb
[root@localhost ~]# mysql -uroot -p
Enter password:

mysql> grant all PRIVILEGES on *.* to lqb@'localhost' identified by '123456'; ###创建一个有权限的访问用户lqb密码设置123456
Query OK, 0 rows affected (0.04 sec)
mysql> update mysql.user set authentication_string=password('123456') where user='lqb' and Host = 'localhost'; ###更新下改用户的密码
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> exit
Bye
2.修改/etc/my.cnf文件创建无密码登录
[root@localhost ~]# vim /etc/my.cnf
[client]
user=lqb
password=123456
[mysqladmin]
host=localhost
user=lqb
password=123456
3.测试是否可以直接访问,如果输入命令mysql -ulqb直接进去说明已OK。
[root@localhost ~]# mysql -ulqb
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 761

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
4.创建mysql监控脚本在目录/usr/local/zabbix/scripts/chk_mysql.sh并赋予相关的权限。
# 获取数据
case $1 in
Uptime)
result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"`
echo $result
;;
Com_update)
result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3`
echo $result
;;
Slow_queries)
result=`${MYSQL_CONN} status |cut -f5 -d":"|cut -f1 -d"O"`
echo $result
;;
Com_select)
result=`${MYSQL_CONN} extended-status |grep -w "Com_select"|cut -d"|" -f3`
echo $result
;;

echo $result

echo $result

echo $result
;;
Com_delete)
result=`${MYSQL_CONN} extended-status |grep -w "Com_delete"|cut -d"|" -f3`
echo $result
;;
Com_commit)
result=`${MYSQL_CONN} extended-status |grep -w "Com_commit"|cut -d"|" -f3`
echo $result
;;
Bytes_sent)
result=`${MYSQL_CONN} extended-status |grep -w "Bytes_sent" |cut -d"|" -f3`
echo $result
;;
Bytes_received)
result=`${MYSQL_CONN} extended-status |grep -w "Bytes_received" |cut -d"|" -f3`
echo $result
5.修改zabbix_agentd.conf添加以下参数:
UserParameter=mysql.version,mysql -V
UserParameter=mysql.status[*], /usr/local/zabbix/scripts/chk_mysql.sh $1
UserParameter=mysql.ping,/usr/local/mysql/bin/mysqladmin -ulqb ping | grep -c alive
[root@localhost scripts]# grep '^[a-Z]' /usr/local/zabbix/etc/zabbix_agentd.conf
LogFile=/tmp/zabbix_agentd.log
Server=172.20.66.110
Hostname=172.21.100.12
RefreshActiveChecks=120
Timeout=20
UserParameter=mysql.version,mysql -V
UserParameter=mysql.status[*], /usr/local/zabbix/scripts/chk_mysql.sh $1
UserParameter=mysql.ping,/usr/local/mysql/bin/mysqladmin -ulqb ping | grep -c alive
6.重启zabbix_agentd客户端服务,查看有没有报错。
