Install
Installation overall steps:
- Prepare Linux server (virtual machine)
- Install Mysql
- Install zabbix (including server agent web)
- Configure mysql to create a table structure for zabbix
- Configure zabbix server
- Start and turn on autostart
Preparations before installation - Mysql
MysqlTo install ZabbixServer, you need to install the database first
course useMysql 5.7
installation steps:
# 安装Mysql yum库
rpm -Uvh http://repo.mysql.com//mysql57-community-release-el7-7.noarch.rpm
# yum安装Mysql
yum -y install mysql-community-server
# 启动Mysql设置开机启动
systemctl start mysqld
systemctl enable mysqld
# 检查Mysql服务状态
systemctl status mysqld
# 第一次启动mysql，会在日志文件中生成root用户的一个随机密码，使用下面命令查看该密码
grep 'temporary password' /var/log/mysqld.log
# 修改root用户密码
mysql -u root -p -h localhost
Enter password:
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Root!@#$';
# 如果你想设置简单密码，需要降低Mysql的密码安全级别
set global validate_password_policy=LOW; # 密码安全级别低
set global validate_password_length=4; # 密码长度最低4位即可
# 然后就可以用简单密码了（课程中使用简单密码，为了方便，生产中不要这样）
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
mysql> grant all privileges on *.* to root@'%' identified by 'root';

yum clean all
b. Install Zabbix Server, front end, Agent
yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent
# 如果只需要安装Agent的话
yum -y install zabbix-agent
c. Initialize the Mysql database
Operate in Mysql
# 登录Mysql 数据库
mysql -uroot -pYourPassword
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';
# 或者: grant all privileges on zabbix.* to zabbix@'%' identified by 'zabbix';
mysql> quit;
Test whether you can log in to Mysql remotely on the Zabbix Server server, and if you can log in, continue down.
Import initial schema and data. You will be prompted to enter your newly created password.
# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
d. Configure the database for Zabbix Server
Edit file /etc/zabbix/zabbix_server.conf
DBPassword=password
DBHost=mysql-host-ip-or-hostname
e. Configure the PHP front end of Zabbix
Edit file /etc/httpd/conf.d/zabbix.conf, uncomment and set the right timezone for you.# php_value date.timezone Asia/Shanghai
Start Zabbix server and agent processes and make it start at system boot:
systemctl restart zabbix-server zabbix-agent httpd # 启动、重启
systemctl enable zabbix-server zabbix-agent httpd # 开机自启
Now your Zabbix server is up and running!
