```

修改zabbix的安装源配置文件，启用前端的源
Change zabbix configurations and start Web GUI.

```bash
# vim /etc/yum.repos.d/zabbix.repo
[zabbix-frontend]
name=Zabbix Official Repository frontend - $basearch
baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/frontend
enabled=1 //此处改为1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
$ vim /etc/yum.repos.d/zabbix.repo
```

```toml
[zabbix-frontend]
name=Zabbix Official Repository frontend - $basearch
baseurl=http://repo.zabbix.com/zabbix/5.0/rhel/7/$basearch/frontend
enabled=1 # change to 1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
```


#### 三、安装MySQL
## Install MySQL

```bash
mkdir mysql-dir
cd mysql-dir
wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar
tar -zxvf mysql-5.7.32-1.el7.x86_64.rpm-bundle.tar
yum install *.rpm -y
$ mkdir mysql-dir
$ cd mysql-dir
$ wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar
$ tar -zxvf mysql-5.7.32-1.el7.x86_64.rpm-bundle.tar
$ yum install *.rpm -y
```

```bash
systemctl start mysqld
$ systemctl start mysqld
```

```bash
cat /var/log/mysqld.log | grep root
$ cat /var/log/mysqld.log | grep root
```

Grep default password.

```bash
2021-07-26T10:50:49.538494Z 1 [Note] A temporary password is generated for root@localhost: **20yyk:Ar67S;**
```

登录数据库:
Login to database.

```mysql
# mysql -uroot -p
```bash
$ mysql -uroot -p
Enter password: 20yyk:Ar67S;
```

配置数据库:
Config database.

```bash
set global validate_password_policy=0;
set global validate_password_length=1;
alter user 'root'@'localhost' identified by 'venus'; #修改root登录密码为venus
alter user 'root'@'localhost' identified by 'venus'; # Change root password

use mysql;
update user set host = '%' where user = 'root';
create user 'zabbix'@'%' identified by '123456';
grant all privileges on zabbix.* to 'zabbix'@'%';
flush privileges;

# 创建zabbix所需的数据库
# Create tables for Zabbix
create database zabbix character set utf8 collate utf8_bin;
```

导入zabbix模版文件:
Import zabbix template files.

```bash
zcat /usr/share/doc/zabbix-server-mysql-5.0.14/create.sql.gz | mysql -uzabbix -p123456 zabbix
$ zcat /usr/share/doc/zabbix-server-mysql-5.0.14/create.sql.gz | mysql -uzabbix -p123456 zabbix
```

## Configure zabbix


#### 四、修改zabbix默认配置文件

1、修改连接数据库的密码:
Change database password.

```bash
# vim /etc/zabbix/zabbix_server.conf
$ vim /etc/zabbix/zabbix_server.conf
DBPassword=123456
```
2、修改nginx和所属地域
Configure Nginx.

```bash
# vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
# 在第6行后边加上一个nginx
$ vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
```

Append `nginx` at the end of line 6.

```
listen.acl_users = apache,nginx
```

Change location to your choice at line 24.

# 在第24行修改zabbix所属的地域
```
php_value[date.timezone] = Asia/shanghai
```

3、配置监听端口和访问方式
Configure port.

```bash
vim /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf
$ vim /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf
server {
listen 80;//取消注释
server_name test.zabbix.com;//取消注释修改成IP或自己的域名
listen 80; # uncomment this line
server_name test.zabbix.com; # uncomment and change to your own ip
```

4、如果是伪装域名则修改本地的hosts文件
Change your hosts file too if using hostname.

```bash
vim /etc/hosts
$ vim /etc/hosts
192.168.xx.xx test.zabbix.com
```

If you are using windows.

window hosts文件也需要添加一下
```bash
# for window hosts
C:\Windows\System32\drivers\etc\hosts
192.168.xxx.xxx test.zabbix.com
```

5、启动服务并设为开机自启
Start service and configure to run on boot.

```bash
# 启动服务
systemctl restart zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
systemctl enable zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
```

6、修改zabbix-agent的配置文件
Change zabbix agent config fie

```bash
cat /etc/zabbix/zabbix_agentd.conf | egrep -v "^$|^#"
$ cat /etc/zabbix/zabbix_agentd.conf | egrep -v "^$|^#"
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=192.168.88.11 //指定zabbix-server的ip地址
Server=192.168.88.11 # point to ip of zabbix-server
Hostname=venus-sealer
Include=/etc/zabbix/zabbix_agentd.d/*.conf
```

#### 四、配置zabbix监控主机
1、在浏览器输入zabbix-server的ip地址或者主机名
## Configure monitoring

Visit your zabbix-server with a browser.

![](/02-zabbix-install.jpg)

2、配置数据库连接地址信息
Configure database connection information.

![](/04-zabbix-hostname.jpg)
![](/05-zabbix-all.jpg)
![](/06-zabbix-finished.jpg)

3、登录到zabbix系统，默认的用户为Admin，密码为zabbix;注意Admin的A是大写字母
Login to zabbix. Default user is `Admin` with `zabbix` as password.
![](/07-zabbix-login.jpg)
![](/08-zabbix-dashboard.jpg)

4、添加zabbix-agent主机
Add zabbix-agent.
