zabbix介紹

Zabbix 是一個基于 WEB 界面的提供分布式系統(tǒng)監(jiān)視以及網(wǎng)絡(luò)監(jiān)視功能的企業(yè)級的開源解決方案。它能監(jiān)視各種網(wǎng)絡(luò)參數(shù)，保證服務(wù)器系統(tǒng)的安全運營；并提供靈活的通知機(jī)制以讓系統(tǒng)管理員快速定位/解決存在的各種問題。

zabbix軟件組成

zabbix-server: 監(jiān)控服務(wù)端

zabbix-agent: 監(jiān)控客戶端

zabbix-web: 監(jiān)控網(wǎng)站服務(wù)

php: 處理動態(tài)請求

mysql: 數(shù)據(jù)庫存儲監(jiān)控數(shù)據(jù)

zabbix: 負(fù)責(zé)收集agent信息匯總告知zabbix-server

1.關(guān)閉防火墻和selinux

[root@zabbix ~]# setenforce 0[root@zabbix ~]# sed -ri '/^SELINUX=/cSELINUX=disabled' /etc/sysconfig/selinux [root@zabbix ~]# systemctl stop firewalld ; systemctl disable firewalld

2.添加zabbix源和epel源

[root@zabbix ~]# rpm -ivh https://mirrors.tuna./zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm ##這里使用的是清華源[root@zabbix ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo ##添加epel源

3.安裝zabbix和相關(guān)服務(wù)組件

[root@zabbix ~]# wget  https://mirrors.tuna./zabbix/zabbix/4.0/rhel/7/x86_64/{zabbix-server-mysql-4.0.20-1.el7.x86_64.rpm,zabbix-web-4.0.22-1.el7.noarch.rpm} ##把這兩個包先拿下來,因為安裝的時候網(wǎng)絡(luò)問題會出現(xiàn)安裝超時

[root@zabbix ~]# yum install -y httpd php zabbix-server-mysql-4.0.20-1.el7.x86_64.rpm  zabbix-web-mysql ###安裝zabbix的服務(wù)程序和web程序

[root@zabbix ~]# yum install -y mariadb-server ##安裝數(shù)據(jù)庫服務(wù)

4.修改zabbix配置文件

[root@zabbix ~]# sed -ri.bak '/# DBPassword=/cDBPassword=zabbix' /etc/zabbix/zabbix_server.conf ##修改zabbix數(shù)據(jù)庫密碼為zabbix[root@zabbix ~]# sed -ri.bak 's/ #(.*)date.timezone.*/\1date.timezone Asia\/Shanghai/' /etc/httpd/conf.d/zabbix.conf ##修改時區(qū)為國內(nèi)

5.配置數(shù)據(jù)庫服務(wù)

[root@zabbix ~]# systemctl start mariadb #啟動數(shù)據(jù)庫[root@zabbix ~]# mysql_secure_installation ##初始化數(shù)據(jù)庫

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the currentpassword for the root user. If you've just installed MariaDB, andyou haven't set the root password yet, the password will be blank,so you should just press enter here.

Enter current password for root (enter for none): OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDBroot user without the proper authorisation.

Set root password? [Y/n] yNew password: Re-enter new password: Password updated successfully!Reloading privilege tables.. ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyoneto log into MariaDB without having to have a user account created forthem. This is intended only for testing, and to make the installationgo a bit smoother. You should remove them before moving into aproduction environment.

Remove anonymous users? [Y/n] y ... Success!

Normally, root should only be allowed to connect from 'localhost'. Thisensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y ... Success!

By default, MariaDB comes with a database named 'test' that anyone canaccess. This is also intended only for testing, and should be removedbefore moving into a production environment.

Remove test database and access to it? [Y/n] n ... skipping.

Reloading the privilege tables will ensure that all changes made so farwill take effect immediately.

Reload privilege tables now? [Y/n] y ... Success!

Cleaning up...

All done! If you've completed all of the above steps, your MariaDBinstallation should now be secure.

Thanks for using MariaDB![root@zabbix ~]# mysql -uroot -p ##登錄數(shù)據(jù)庫Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g.Your MariaDB connection id is 8Server version: 5.5.65-MariaDB MariaDB Server

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

[root@zabbix ~]# zcat /usr/share/doc/zabbix-server-mysql-4.0.20/create.sql.gz  | mysql -uzabbix -pzabbix zabbix  ##將數(shù)據(jù)表寫入到zabbix庫中

6.啟動zabbix和相關(guān)服務(wù)

[root@zabbix ~]# systemctl start zabbix-server.service httpd mariadb.service[root@zabbix ~]# systemctl enable zabbix-server.service httpd mariadb.serviceCreated symlink from /etc/systemd/system/multi-user.target.wants/zabbix-server.service to /usr/lib/systemd/system/zabbix-server.service.Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
