Zabbix email alarm

1. Computer login Netease mailbox configuration (save the authorization code!)

2. Install and configure the mail server on the server side (huyang1):

1. Install mail service

yum install -y mailx dos2unix

mailx -V

2. Modify the configuration file

vim /etc/mail.rc

The configuration is as follows: (the last three lines)

Remarks: //Add at the end of this file, specify the receiving email address, specify the email server address, and specify the authorization code of the receiving email address. It is not the password of the 163 mailbox, but the authorization code. After logging in to the 163 Netease email address, --Settings--Enable smtp and pop3--click the client to generate the authorization code--use this authorization code to assign to this configuration file;

3. Send test content

echo "test mail from huyang1"| mail -s"test mail" [email protected] //Send test content

email view

3. Edit zabbix_server.conf to quote the mail script:

vim /usr/local/zabbix/etc/zabbix_server.conf

The configuration is as follows:

cd /usr/local/zabbix/share/zabbix/alertscripts

vim mail.sh

The configuration is as follows:

Remarks: //Write the alarm email script, adjust the syntax position of the mail command, and use the dos2unix command to convert characters, so as to avoid the error of ATT00001.

bt=$2 sjr=$1 defines sender header and recipient information

FILE=/tmp/mailtmp.txt defines the file path

/usr/bin/dos2unix -k $FILE Use the dos2unix command to convert characters, avoiding the ATT00001.bin error due to the received mail not displaying the normal mail content;

/bin/mail -s "$bt" "$sjr" <$FILE execute mail sending command

chmod 777 mail.sh //weight the script

chown zabbix:zabbix mail.sh //Change the group and owner

touch /tmp/mailtmp.txt //Create information file

chmod 777 /tmp/mailtmp.txt //weighting

chown zabbix:zabbix /tmp/mailtmp.txt //Change to the group and owner

Remarks: //Pay attention to the ownership and permissions of files and alarm scripts; the ownership of script files and files storing email messages must be zabbix

./mail.sh [email protected] "test mail2" "test mail from huyang1 test2" //Script test

4. Configure zabbix web monitoring item email alarm:

(1) Operation idea :

Monitoring--create alarm media type--update the alarm media type used by the user--create action (triggered according to the trigger)--verify;

(2) huyang1 web operation :

Remarks: Enter the name of the created alarm medium type, specify the type as a script, and enter the huyang1 terminal

The name of the script in the /usr/local/zabbix/share/zabbix/alertscripts directory, ensure that the script belongs to zabbix, and the script permission is 777, set the script parameters below, that is, the syntax of sending emails: the title content of the script recipient must be filled in strictly according to this standard;

The three script parameters are as follows:

$1 {ALERT.SENDTO}

$2 {ALERT.SUBJECT}

$3 {ALERT.MESSAGE}

Example: as follows

Configure the alarm media type used by users in zabbix and the mailbox for receiving emails;

Example: as follows
