zabbix4.0 deployment
zabbix server needs LAMP or LNMP environment, so there are many installation methods here. We choose a relatively simple installation method and install it directly with the source provided by the official.
Deployment preparation
[root@zabbix-server ~]# uname -a Linux zabbix-server 3.10.0-1062.18.1.el7.x86_64 #1 SMP Tue Mar 17 23:49:17 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux [root@zabbix-server ~]# cat /etc/centos-release CentOS Linux release 7.7.1908 (Core)
When the firewall is off, turn off SELinux
yum -y update
Install PHP
yum install -y php php-fpm vim /etc/php.ini shift+g Add the following content to the end: date.timezone = Asia/Shanghai max_execution_time = 300 post_max_size = 32M max_input_time = 300 memory_limit = 128M makefile systemctl start php-fpm
Install mariadb
Detect conflicts
Be sure to uninstall MySQL cleanly, otherwise there will be inexplicable problems
systemctl stop mysqld rpm -aq mysql* yum remove -y `rpm -aq mysql*` [root@server2 ~]# find / -name mysql /var/lib/mysql /var/lib/mysql/mysql /usr/share/mysql [root@server1 ~]# rm -rf /var/lib/mysql /var/lib/mysql/mysql /usr/share/mysql [root@server2 ~]# ll /etc/my.cnf -rw-r--r-- 1 root root 570 Sep 21 2016 /etc/my.cnf [root@server2 ~]# rm -rf /etc/my.cnf Test: [root@server2 ~]# rpm -aq mysql*
Prepare installation package
yum -y install mariadb mariadb-server systemctl start mariadb systemctl enable mariadb
You must start it here before you can generate a log. For some versions, you need to find the password in the log.
Database permission initialization
/usr/bin/mysql_secure_installation mysql -uroot mysql -uroot -p
Initialization process:
01 [root@test ~]# /usr/bin/mysql_secure_installation 02 NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL 03 SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! 04 05 In order to log into MySQL to secure it, we'll need the current 06 password for the root user. If you've just installed MySQL, and 07 you haven't set the root password yet, the password will be blank, 08 so you should just press enter here. 09 10 Enter current password for root (enter for none):<---Enter the current root Password, because we haven't set it yet, just enter 11 OK, successfully used password, moving on... 12 13 Setting the root password ensures that nobody can log into the MySQL 14 root user without the proper authorisation. 15 16 Set root password? [Y/n] Y <---Set or not root Password, of course. Enter it Y enter 17 New password: <---input root Enter the password and press enter. There will be no display during the input process 18 Re-enter new password: <---Enter again root Enter the password and press enter. There will be no display during the input process 19 Password updated successfully! 20 Reloading privilege tables.. 21 ... Success! 22 23 By default, a MySQL installation has an anonymous user, allowing anyone 24 to log into MySQL without having to have a user account created for 25 them. This is intended only for testing, and to make the installation 26 go a bit smoother. You should remove them before moving into a 27 production environment. 28 29 Remove anonymous users? [Y/n] Y <---Delete anonymous user? Enter Y enter 30 ... Success! 31 32 Normally, root should only be allowed to connect from 'localhost'. This 33 ensures that someone cannot guess at the root password from the network. 34 35 Disallow root login remotely? [Y/n] Y <---Delete prohibition root User remote login, of course, prohibited, input Y enter 36 ... Success! 37 38 By default, MySQL comes with a database named 'test' that anyone can 39 access. This is also intended only for testing, and should be removed 40 before moving into a production environment. 41 42 Remove test database and access to it? [Y/n] <---Delete test database test，Delete, enter Y enter 43 - Dropping test database... 44 ... Success! 45 - Removing privileges on test database... 46 ... Success! 47 48 Reloading the privilege tables will ensure that all changes made so far 49 will take effect immediately. 50 51 Reload privilege tables now? [Y/n] Y <---Refresh permissions, enter Y enter 52 ... Success! 53 54 Cleaning up... 55 56 All done! If you've completed all of the above steps, your MySQL 57 installation should now be secure. 58 59 Thanks for using MySQL!

Install apache
yum install -y httpd
Installing zabbix
rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent -y
Pay attention to whether there are errors reported.
Common error handling:
Solve Errno 256 error reporting
yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent The following errors are reported: Error downloading packages: zabbix-web-4.0.19-1.el7.noarch: [Errno 256] No more mirrors to try. zabbix-agent-4.0.19-1.el7.x86_64: [Errno 256] No more mirrors to try. zabbix-server-mysql-4.0.19-1.el7.x86_64: [Errno 256] No more mirrors to try. reason: zabbix The source itself is a problem because the server is abroad. [root@localhost ~]# cd /etc/yum.repos.d [root@localhost yum.repos.d]# ls CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo zabbix.repo [root@localhost yum.repos.d]# vim zabbix.repo Add the following: [zabbix] name=Zabbix Official Repository - $basearch baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/$basearch/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591 [zabbix-non-supported] name=Zabbix Official Repository non-supported - $basearch baseurl=http://repo.zabbix.com/non-supported/rhel/7/$basearch/ enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX gpgcheck=1
Import zabbix data
Create library and authorize
Before creating a new bbzaix data library, you must manage the bbzaix data library
Create zabbix library, create zabbix user, and authorize.
[root@pokes02 ~]# mysql -uroot -p password :123456 mysql> create database zabbix character set utf8 collate utf8_bin; #Create zabbix Library mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '******'; #Create zabbix user with password***** mysql> grant all on zabbix.* to 'zabbix'@'localhost' identified by '*******' with grant option; #Authorize zabbix users to have permission to manage zabbix libraries mysql> flush privileges; #Refresh permissions mysql> quit;
The above libraries, users and authorizations have been created. Now let's find the data to import
View the database provided by zabbix
[root@pokes02 ~]# ls /usr/share/doc/zabbix-server-mysql-4.0.38/create.sql.gz /usr/share/doc/zabbix-server-mysql-4.0.38/create.sql.gz [root@pokes02 ~]# gzip -d /usr/share/doc/zabbix-server-mysql-4.0.38/create.sql.gz [root@pokes02 ~]# mysql -uzabbix -p******* zabbix < /usr/share/doc/zabbix-server-mysql-4.0.38/create.sql # *****It's a password
Note: if an error is reported when importing data here, it is because you did not authorize successfully, or did not build a zabbix library, or the zabbix user password is wrong, etc.
Restart service
systemctl restart zabbix-server.service systemctl restart zabbix-agent.service systemctl restart httpd.service
Zabbix configuration
Modify the DBPassword password. After the database is imported, you need to configure the database password for Zabbix and modify / etc / Zabbix / Zabbix_ server. In conf
vim /etc/zabbix/zabbix_server.conf #Tap / search DBPassword DBPassword=******** #The password here is the password of the database zabbix user, not the root password
The default is to add a # number for annotation, and to cancel the annotation and add a password
Configure PHP time zone
Configure PHP time zone for ZABBIX: modify and edit the file / etc / httpd / conf.d/zabbix.com Conf, uncomment and set the correct time zone for you.
vim /etc/httpd/conf.d/zabbix.conf php_value date.timezone Asia/Shanghai
Start Zabbix service
Restart service: systemctl restart zabbix-server systemctl restart zabbix-agent systemctl restart httpd.service Configure startup: systemctl enable zabbix-server systemctl enable zabbix-agent systemctl enable httpd
Access graphical interface
After startup, you can run: http://IP/zabbix Enter the configuration interface of ZABBIX.
The default login account and password are Admin and zabbix
