CentOS7部署Zabbix3.4
1.安装环境
[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.安装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.安装Zabbix-server和Zabbix-agent
yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent
4.安装MySQL的YUM源
检查
ls /etc/yum.repos.d/
安装
rpm -ivh https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
检查
ls /etc/yum.repos.d/
5.安装MySQL服务端
yum -y install mysql-community-server
6.启动MySQL服务并设置开机自启动
启动
systemctl start mysqld
systemctl enable mysqld
检查
[root@live4what ~]# netstat -lntup |grep :3306
tcp6 0 0 :::3306 :::* LISTEN 63750/mysqld
7.进入MySQL并修改默认密码
初始密码：
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
修改密码（因密码复杂度有要求，修改全局变量）
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.导入Zabbix的数据
cd /usr/share/doc/zabbix-server-mysql-3.4.12/
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
检查
mysql> show databases
mysql> use zabbix
mysql> show tables
利用-e参数优化
9.修改Zabbix的配置文件，给服务授权并启动Zabbix-server
备份并检查（备份是个好习惯）
cp /etc/zabbix/zabbix_server.conf{,.backup}
ll /etc/zabbix/zabbix_server.conf{,.backup}
编辑
vim /etc/zabbix/zabbix_server.conf
检查
10.启动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
这里有个坑，当执行systemctl start zabbix-server.service后，会有如下提示信息：
[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.
解决方法：根据提示和日志
按提示运行systemctl status zabbix-server.service,输出信息如下：
`[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)

Aug 27 13:07:54 live4what.com systemd[1]: zabbix-server.service failed.
按提示运行journalctl -xe输出信息如下：

The result is failed.

查看/var/log/zabbix-server.log日志信息：
[root@live4what ~]# ll /var/log/zabbix/
total 0
没有找到日志信息。
解决方法（对比备份文件，加入LogFile参数）：
[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
上面问题解决后，还有可能出现这种情况，就是执行 systemctl start zabbix-server.service后感觉卡在那了，再次运行journalctl -xe发现：
[root@live4what ~]# journalctl -xe
......(此处省略)

Aug 27 13:43:54 live4what.com chronyd[753]: Source 193.228.143.14 replaced with 69.60.114.223
解决方法：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
此时会有报错：主要分以下几种：
10.编辑Zabbix前端PHP文件
vim /etc/httpd/conf.d/zabbix.conf
11.启动Apache服务
systemctl start httpd
systemctl enable httpd
检查
netstat -lntup | grep :80
测试：
无法访问问题：
关闭CentOS7的防火墙
systemctl stop firewalld.service
12.Zabbix Web管理站点配置
浏览器打开http://修改为服务器地址/zabbix
欢迎界面
PHP需求检查
数据库配置，用于连接MySQL数据库
Zabbix服务器详细信息
安装信息列表
安装完成
如果安装失败:一般情况是php对zabbix没有写权限
登陆zabbix
默认用户名：Admin，密码：zabbix
13.过程中遇到的问题（已解决）
(1) web前端无法安装
报错：
解决方法：
[root@live4what ~]# ll /etc/zabbix

(2)zabbix-server无法正常启动
报错：
解决方法：
(3) 内存溢出
报错：zabbix server is not running
查看日志less /var/log/zabbix/zabbix_server.log发现：
......（此处省略）

解决方法：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服务无法访问
关闭防火墙
systemctl stop firewalld.service
(5) 网页安装zabbix提示不能创建配置文件
解决方法：
设置 web服务器用户在zabbix网页的conf/目录具有写权限，配置文件会自动保存。
