一、zabiix分布式原理圖：
zabbix分布式就相當(dāng)于在基礎(chǔ)環(huán)境中搭建了一個(gè)中轉(zhuǎn)站zabbix-porxy，porxy可以把其監(jiān)控項(xiàng)全部收納起來(lái)，等待zabbix-server服務(wù)器的讀取。（用分布式項(xiàng)目?jī)?yōu)勢(shì)，可以在內(nèi)網(wǎng)中對(duì)要進(jìn)行監(jiān)控的服務(wù)器進(jìn)行監(jiān)控）
二、準(zhǔn)備實(shí)驗(yàn)環(huán)境：
服務(wù)器角色 ip 服務(wù)器名
zabbix-server 10.0.0.71 zabbix
zabbix-proxy 10.0.0.7/172.16.1.7 web01
zabbix-agent 172.16.1.20 web02-jk
需要部署的程序：
zabbix-server 部署的程序：zabbix-server-mysql 、zabbix-web-mysql、mariadb-server、httpd（內(nèi)外網(wǎng)都需要）
zabbix-proxy 部署的程序：mariadb-server、zabbix-proxy（內(nèi)外網(wǎng)都需要）
zabbix-agent 部署的程序：zabbix-agent、把外網(wǎng)關(guān)閉（只保存內(nèi)網(wǎng)172.16.1.20）
1、 zabbix-server的搭建在第59課已經(jīng)有搭建過(guò)，這里不做說(shuō)明。
2、 zabbix-proxy的環(huán)境部署（在web01上部署）：
2.1 官網(wǎng)下載zabbix源：
2.2 修改zabbix.repo源：
[root@web01 yum.repos.d]# vim zabbix.repo
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/$basearch/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=https://mirrors.tuna.tsinghua.edu.cn/zabbix/non-supported/rhel/7/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=0
2.3 安裝zabbix-proxy：
[root@web01 yum.repos.d]# yum install -y zabbix-proxy-mysql
[root@web01 yum.repos.d]# rpm -qa zabbix-proxy-mysql
zabbix-proxy-mysql-4.0.10-1.el7.x86_64
2.4 安裝mariadb-server：
[root@web01 ]# yum install -y mariadb-server
[root@web01 yum.repos.d]# rpm -qa mariadb-server
mariadb-server-5.5.60-1.el7_5.x86_64
2.5 優(yōu)化數(shù)據(jù)庫(kù)（mysql安全初始化）：
[root@zabbix yum.repos.d]# mysql_secure_installation
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 current
password for the root user. If you've just installed MariaDB, and
you 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 MariaDB
root user without the proper authorisation.
Set root password? [Y/n] n
... skipping.
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures 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 can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will 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 MariaDB
installation should now be secure.
Thanks for using MariaDB!
2.6 創(chuàng)建數(shù)據(jù)庫(kù)：
[root@web01 ~]# mysql

2.7 導(dǎo)入初始化數(shù)據(jù)庫(kù)并啟動(dòng)數(shù)據(jù)庫(kù)、設(shè)置開機(jī)自啟：
[root@web01 ~]# zcat /usr/share/doc/zabbix-proxy-mysql-4.0.10/schema.sql.gz |mysql -uzabbix_proxy -p123456 zabbix_proxy
[root@web01 ~]#systemctl start mariadb.server
[root@web01 ~]#systemctl enable mariadb.server
2.8 修改zabbix-proxy配置文件，啟動(dòng)proxy，并開機(jī)自啟：
[root@web01 ~]# systemctl start zabbix-proxy
[root@web01 ~]# systemctl enable zabbix-proxy

2.10 添加hosts解析：
zabbix-server服務(wù)器上添加：
10.0.0.7 web01 sh-porxy
