One . Prepare the environment

1.  Environment initialization

(1) Configure the domain name

hostnamectl set-hostname  server
hostnamectl set-hostname  agent01
hostnamectl set-hostname  agent02

cat > /etc/hosts << EOF
192.168.10.1 server
192.168.10.2 agent01
192.168.10.3 agent02
EOF

（2） Turn off firewall , Close the kernel ,

systemctl stop firewalld  && systemctl disable firewalld
setenforce 0	&& sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

（3） Time synchronization

yum install chrony -y 
systemctl enable chronyd 
systemctl start chronyd 
chronyc sources

2.yum Source installation

 wget -O /etc/yum.repos.d/aliyun.base.repo http://mirrors.aliyun.com/repo/Centos-7.repo http://mirrors.aliyun.com/repo/Centos-7.repo
 rpm -Uvh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Two . install MySQL

1. stay server Install the database on the host

yum install -y mariadb-server 
systemctl start mariadb 
systemctl enable mariadb 

 It is also possible to install MySQL For the first time, the database lets you set the password , The order is as follows ：
ph
 First, set the password , You will be prompted to enter the password first 
Enter current password for root (enter for none):<– First run direct return

New password: <–  Set up root User's password 
Re-enter new password: <–  Enter your password again 
 Other configuration 
Remove anonymous users? [Y/n] <–  Whether to delete anonymous users , enter 
Disallow root login remotely? [Y/n] <– Whether to ban root Remote login , enter ,
Remove test database and access to it? [Y/n] <–  Whether or not to delete test database , enter 
Reload privilege tables now? [Y/n] <–  Whether to reload the permission table , enter 
 initialization MariaDB complete , Next, test login 
mysql -uroot -ppassword
 complete .

2. Sign in mysql Create database and authorize

 mysql 			## The initial password is empty 
mysql> CREATE DATABASE zabbix character set utf8 collate utf8_bin;
 CREATE DATABASE zabbix_proxy character set utf8 collate utf8_bin; 
 USE mysql;

UPDATE mysql.user SET password = PASSWORD('zabbix') WHERE user = 'root';  ## Set up root  The account password is 'zabbix'
mysql> GRANT ALL PRIVILEGES ON zabbix.* TO [email protected]'localhost' IDENTIFIED BY 'zabbix'; ## to grant authorization zabbix  Account password 'zabbix' Local access  zabbix  database 
mysql> GRANT ALL PRIVILEGES ON zabbix.* TO [email protected]'%' IDENTIFIED BY 'zabbix';  ## to grant authorization zabbix  Account password 'zabbix' The remote access  zabbix  database 

mysql>GRANT ALL PRIVILEGES ON zabbix_proxy.* TO 'zabbix'@'localhost' IDENTIFIED BY 'zabbix';  ## to grant authorization zabbix  Account password 'zabbix' Local access  zabbix\_proxy  database 

mysql>GRANT ALL PRIVILEGES ON zabbix_proxy.* TO 'zabbix'@'%' IDENTIFIED BY 'zabbix';  ## to grant authorization zabbix  Account password 'zabbix' The remote access  zabbix\_proxy  database
