1、修改agentd端的userparameter_mysql.conf

[root@mysql1 zabbix_agentd.conf.d]# vi userparameter_mysql.conf
# For all the following commands HOME should be set to the directory that has .my.cnf file with password information.

# Flexible parameter to grab global variables. On the frontend side, use keys like mysql.status[Com_insert].
# Key syntax is mysql.status[variable].
#UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/usr/local/zabbix/etc mysql -N | awk '{print $$2}' #原来的语句
UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/usr/local/zabbix/etc /usr/local/mysql/bin/mysql -N | awk '{print $$2}' #修改后的语句,下面一样

# Flexible parameter to determine database or table size. On the frontend side, use keys like mysql.size[zabbix,history,data].
# Key syntax is mysql.size[<database>,<table>,<type>].
# Database may be a database name or "all". Default is "all".
# Table may be a table name or "all". Default is "all".
# Type may be "data", "index", "free" or "both". Both is a sum of data and index. Default is "both".
# Database is mandatory if a table is specified. Type may be specified always.
# Returns value in bytes.
# 'sum' on data_length or index_length alone needed when we are getting this information for whole database instead of a single table
UserParameter=mysql.size[*],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='$2'");" | HOME=/usr/local/zabbix/etc /usr/local/mysql/bin/mysql -N
#UserParameter=mysql.size[*],echo "select sum($(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=/usr/local/zabbix/etc mysql -N

UserParameter=mysql.ping,HOME=/usr/local/zabbix/etc /usr/local/mysql/bin/mysqladmin ping | grep -c alive
#UserParameter=mysql.ping,HOME=/usr/local/zabbix/etc mysqladmin ping | grep -c alive
UserParameter=mysql.version,/usr/local/mysql/bin/mysql -V
#UserParameter=mysql.version,mysql -V

重启

2、在服务端测试连接

zabbix_get -s 173.82.212.248 -k mysql.ping
#==============错误信息================
/usr/local/mysql/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'zabbix'@'localhost' (using password: NO)'
0

解决办法:
1、创建.mf.cnf数据库配置文件

vim /etc/zabbix/.my.cnf
[mysql]
host=localhost
user=root
password='654321'
socket=/tmp/mysql.sock
[mysqladmin]
host=localhost
user=root
password='654321'
socket=/tmp/mysql.sock
这里一定要注意 密码需要加上引号,要不然识别不到

2、修改userparameter_mysql.conf配置文件

vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
#将
HOME=/usr/local/zabbix/etc
#修改为
HOME=/etc/zabbix

然后重启service zabbix-agent restart

接下来前往服务端测试连接是否成功

zabbix_get -s 127.0.0.1 -k mysql.ping
1

没报错就说明成功了
