二.Zabbix Server 配置監控無密碼的MariaDB數據庫ui

1>.建立主機spa

2>.配置host界面

3>.配置zabbix監控數據庫的模板

4>.主機添加完成

5>.以下圖所示，zabbix默認有14個監控項

6>.查看監控MySQL的圖形

二：

一.Zabbix-agent端的配置

1>.爲數據庫設置密碼

[root@node102 ~]# mysql -uroot -pyinzhengjie　　　　　　　　　　　　　　　　　　　　　　　　　　#看見沒？默認是不須要密碼就能夠登陸的！咱們想要設置密碼的話，就得進行受權操做！
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
[root@node102 ~]#

[root@node102 ~]#

2>.修改zabbix-agent端的數據庫配置文件並重啓服務

[root@node102 ~]# cat /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf  | egrep -v '^#|^$'
UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -uroot -pyinzhengjie -N | awk '{print $$2}'　　　　　　#這裏須要修改一些
UserParameter=mysql.size[*],bash -c 'echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/var/lib/zabbix mysql -N'
UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin ping -uroot -pyinzhengjie | grep -c alive　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　#除了修改第一個，咱們還須要修改這一行，把上面的配置的用戶和密碼加入進去！
UserParameter=mysql.version,mysql -V
[root@node102 ~]# 
[root@node102 ~]# 
[root@node102 ~]# systemctl restart zabbix-agent
[root@node102 ~]# 
[root@node102 ~]#

二.Zabbix Server監控Agent端的數據庫

　　服務端配置大同小異，可參考上面無密碼監控mysql

三：

一.zabbix-agent端配置

1>.修改zabbix的item配置文件

[root@node102 ~]# cat /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf  | egrep -v '^#|^$'
UserParameter=mysql.status[*],echo "show global status where Variable_name='$3';" | HOME=/var/lib/zabbix mysql -u$1 -p$2 -N | awk '{print $$2}'　　　　　　　　　　#注意這裏修改了3處
UserParameter=mysql.size[*],bash -c 'echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/var/lib/zabbix mysql -N'
UserParameter=mysql.ping[*],HOME=/var/lib/zabbix mysqladmin ping -u$1 -p$2 | grep -c alive　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 #這裏也修改了3處
UserParameter=mysql.version,mysql -V
[root@node102 ~]# 
[root@node102 ~]# systemctl restart zabbix-agent
[root@node102 ~]#

2>.使用zabbix-Server測試

[root@node101 ~]# zabbix_get -s node102.yinzhengjie.org.cn -k mysql.status[root,yinzhengjie,Uptime]　　　　　　　　　　#很顯然，咱們是能夠取到值的！
3128
[root@node101 ~]# 
[root@node101 ~]# zabbix_get -s node102.yinzhengjie.org.cn -k mysql.status[root,yinzhengjie,Uptime]
3129
[root@node101 ~]# 
[root@node101 ~]# zabbix_get -s node102.yinzhengjie.org.cn -k mysql.status[root,yinzhengjie,Uptime]
3130
[root@node101 ~]# 
[root@node101 ~]#

3>.建立MySQL測試用戶

[root@node102 ~]# mysql -uroot -pyinzhengjie

Your MariaDB connection id is 728

MariaDB [(none)]> 
MariaDB [(none)]> GRANT ALL ON *.* TO  monitor@'localhost' IDENTIFIED BY 'yinzhengjie2019';

MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]> quit
Bye
[root@node102 ~]#

二.zabbix-Server端配置

1>.找到zabbix-server的數據庫模板

2>.添加zabbix的變量

3>.更新模板

4>.重複下圖操做，將默認的13個監控項的key都添加2個變量

5>.數據庫模板配置完成

6>.配置被監控的數據庫的用戶名和密碼

7>.配置完成

8>.在zabbix-server端讓配置當即生效

[root@node101 ~]# zabbix_server -R config_cache_reload　　　　　　　　#從新加載配置信息
zabbix_server [4009]: command sent successfully
[root@node101 ~]# 
[root@node101 ~]#

9>.查看監控圖像
