1.安裝環境
[root@live4what tools]# uname -a
Linux live4what.com 3.10.0-862.el7.x86_64 #1 SMP Fri Apr 20 16:44:24 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@live4what tools]#
2.安裝Zabbix的YUM源
rpm -ivh https://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm
3.安裝Zabbix-server和Zabbix-agent
yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent
4.安裝MySQL的YUM源
檢查
ls /etc/yum.repos.d/
安裝
rpm -ivh https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
檢查
ls /etc/yum.repos.d/
5.安裝MySQL服務端
yum -y install mysql-community-server
6.啟動MySQL服務並設置開機自啟動
啟動
systemctl start mysqld
systemctl enable mysqld
檢查
[root@live4what ~]# netstat -lntup |grep :3306
tcp6 0 0 :::3306 :::* LISTEN 63750/mysqld
7.進入MySQL並修改默認密碼
初始密碼：
cat /var/log/mysqld.log | grep password
[root@live4what ~]# cat /var/log/mysqld.log | grep password
2018-08-27T11:39:57.501993Z 1 [Note] A temporary password is generated for root@localhost: 4s_gcf!#pcrL
修改密碼（因密碼復雜度有要求，修改全局變量）
mysql> ALTER USER USER() IDENTIFIED BY 'guojinyu@it';
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.01 sec)
mysql> ALTER USER USER() IDENTIFIED BY 'guojinyu@it';
Query OK, 0 rows affected (0.00 sec)
8.導入Zabbix的數據
cd /usr/share/doc/zabbix-server-mysql-3.4.12/
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
檢查
mysql> show databases
mysql> use zabbix
mysql> show tables
利用-e參數優化
9.修改Zabbix的配置文件，給服務授權並啟動Zabbix-server
備份並檢查（備份是個好習慣）
cp /etc/zabbix/zabbix_server.conf{,.backup}
ll /etc/zabbix/zabbix_server.conf{,.backup}
編輯
vim /etc/zabbix/zabbix_server.conf
檢查
10.啟動zabbix-server
chown -R zabbix:zabbix /etc/zabbix/
chmod -R 755 /etc/zabbix/
systemctl status zabbix-server.service
systemctl stop zabbix-server.service
systemctl start zabbix-server.service
這里有個坑，當執行systemctl start zabbix-server.service后，會有如下提示信息：
[root@live4what ~]# systemctl start zabbix-server.service
Job for zabbix-server.service failed because the control process exited with error code. See "systemctl status zabbix-server.service" and "journalctl -xe" for details.
解決方法：根據提示和日志
按提示運行systemctl status zabbix-server.service,輸出信息如下：
`[root@live4what ~]# systemctl status zabbix-server.service
● zabbix-server.service - Zabbix Server
Loaded: loaded (/usr/lib/systemd/system/zabbix-server.service; enabled; vendor preset: disabled)

按提示運行journalctl -xe輸出信息如下：

The result is failed.

查看/var/log/zabbix-server.log日志信息：
[root@live4what ~]# ll /var/log/zabbix/
total 0
沒有找到日志信息。
解決方法（對比備份文件，加入LogFile參數）：
[root@live4what tools]# vim /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=guojinyu@it
LogFile=/var/log/zabbix/zabbix_server.log
上面問題解決后，還有可能出現這種情況，就是執行 systemctl start zabbix-server.service后感覺卡在那了，再次運行journalctl -xe發現：
[root@live4what ~]# journalctl -xe
......(此處省略)

解決方法：在zabbix-server配置文件中加入如下信息：
[root@live4what ~]# vim /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=guojinyu@it
LogFile=/var/log/zabbix/zabbix_server.log
PidFile=/var/run/zabbix/zabbix_server.pid
此時會有報錯：主要分以下幾種：
10.編輯Zabbix前端PHP文件
vim /etc/httpd/conf.d/zabbix.conf
11.啟動Apache服務
systemctl start httpd
systemctl enable httpd
檢查
netstat -lntup | grep :80
測試：
無法訪問問題：
關閉CentOS7的防火牆
systemctl stop firewalld.service
12.Zabbix Web管理站點配置
瀏覽器打開http://修改為服務器地址/zabbix
歡迎界面
PHP需求檢查
數據庫配置，用於連接MySQL數據庫
Zabbix服務器詳細信息
安裝信息列表
安裝完成
如果安裝失敗:一般情況是php對zabbix沒有寫權限
登陸zabbix
默認用戶名：Admin，密碼：zabbix
13.過程中遇到的問題（已解決）
(1) web前端無法安裝

(3) 內存溢出
報錯：zabbix server is not running
查看日志less /var/log/zabbix/zabbix_server.log發現：

解決方法：在zabbix-server配置文件中加入如下信息：
[root@live4what ~]# vim /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=guojinyu@it
LogFile=/var/log/zabbix/zabbix_server.log
PidFile=/var/run/zabbix/zabbix_server.pid
CacheSize=512M
(4) Tomcat服務無法訪問
關閉防火牆
systemctl stop firewalld.service
(5) 網頁安裝zabbix提示不能創建配置文件
解決方法：
設置 web服務器用戶在zabbix網頁的conf/目錄具有寫權限，配置文件會自動保存。
