centos7安装zabbix3.4或4.0-11904875
一、系统环境cat /etc/redhat-release
CentOS Linux> 关闭防火墙及selinux
systemctl stop firewalld.service
systemctl disable firewalld.service
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
grep SELINUX=disabled /etc/selinux/config
setenforce 0
Zabbix 官方命令安装步骤：
a. Install Repository with MySQL database
rpm -i https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
b. Install Zabbix server, frontend, agent
yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent
c. Create initial database
mysql -uroot -p
password
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost> mysql> quit;
Import initial schema and data. You will be prompted to enter your newly created password.
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
d. Configure the database for Zabbix server
Edit file /etc/zabbix/zabbix_server.conf
DBPassword=password
e. Configure PHP for Zabbix frontend
Edit file /etc/httpd/conf.d/zabbix.conf, uncomment and set the right timezone for you.
php_value date.timezone Europe/Riga【Aisa/Shanghai】
f. Start Zabbix server and agent processes
Start Zabbix server and agent processes and make it start at system boot:
systemctl restart zabbix-server zabbix-agent httpd
systemctl enable zabbix-server zabbix-agent httpd
Connect to your newly installed Zabbix frontend: http://server_ip_or_name/zabbix
Follow steps described in Zabbix documentation: Installing frontend
二、数据库安装及配置
1、MariaDB概述
MariaDB数据库管理系统是MySQL的一个分支，MariaDB的目的是完全兼容MySQL，包括API和命令行
2、安装mariadb
yum install mariadb-server mariadb -y
mariadb数据库的相关命令是：
systemctl start mariadb#启动MariaDB
systemctl stop mariadb#停止MariaDB
systemctl restart mariadb#重启MariaDB
systemctl enable mariadb#设置开机启动
安装MySQL
1.下载 Mysql yum包
wget http://repo.mysql.com/mysql57-community-release-el7-10.noarch.rpm
2.安转软件源
sudo rpm -Uvh mysql57-community-release-el7-10.noarch.rpm
3安装mysql服务端
yum install-ymysql-community-server 【时间较长越10-20分钟】
4首先启动mysql
systemctl status mysqld.service / service mysqld start
如使用mysql -u root -p 报错ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password:yes)
则：
systemctl stop mysqld.service
修改/etc/my.cnf 在最后加上，skip-grant-tables
mysql -u root 【不要用P已经跳过密码了】
UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
删除my.cnf中的skip-grant-tables 重启mysql
systemctlstart/stopmysqld.service
2、Zabbix3.4安装
rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm
yum install zabbix-server-mysql zabbix-web-mysqlzabbix-agent -y
3、创建数据库
create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to zabbix@localhost> Zabbix 命令报错：
mysql> create database zabbix character set utf8 collate utf8_bin;
ERROR 1820 (HY000): You must reset your password using> mysql> set password=password("复杂密码"); 【不改策略有密码复杂度】
重启mysql
4、导入数据
zcat /usr/share/doc/zabbix-server-mysql-3.4.0/create.sql.gz | mysql -uzabbix -p zabbix
【让你输入的密码是之前创建的复杂密码】
Start Zabbix server and agent processes
systemctl restart zabbix-server zabbix-agent httpd
systemctl enable zabbix-server zabbix-agent httpd
5、配置数据库用户及密码
/etc/zabbix/zabbix_server.conf
DBPassword=password【之前创建的复杂密码】
/etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai【上海4.0可用，3.4是Aisa/Chongqing 上海有问题好像】
6、启动zabbix server并设置开机启动
systemctl enable zabbix-server
systemctl start zabbix-server
8、SELinux配置
setsebool -P httpd_can_connect_zabbix on
setsebool -P httpd_can_network_connect_db on
9、启动httpd并设置开机启动
systemctl start httpd
systemctl enable httpd
Date.timezone 过不了
解决方法：
查看php.ini配置文件的设置
# vi /etc/httpd/conf.d/zabbix.conf
进入后有server not run
cannot set resource limit: Permission denied
setenforce 0
开启zabbix-server服务 ok
systemctl start zabbix-server
外部地址无法访问，只能本机访问zabbix
>> 开启端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
命令含义：
--zone #作用域
--add-port=80/tcp #添加端口，格式为：端口/通讯协议
--permanent #永久生效，没有此参数重启后失效
>> 重启防火墙
firewall-cmd --reload
常用命令介绍
firewall-cmd --state ##查看防火墙状态，是否是running
firewall-cmd --reload ##重新载入配置，比如添加规则之后，需要执行此命令
firewall-cmd --get-zones ##列出支持的zone
firewall-cmd --get-services ##列出支持的服务，在列表中的服务是放行的
firewall-cmd --query-service ftp ##查看ftp服务是否支持，返回yes或者no
firewall-cmd --add-service=ftp ##临时开放ftp服务
firewall-cmd --add-service=ftp --permanent ##永久开放ftp服务
firewall-cmd --remove-service=ftp --permanent##永久移除ftp服务
firewall-cmd --add-port=80/tcp --permanent ##永久添加80端口
iptables -L -n ##查看规则，这个命令是和iptables的相同的
man firewall-cmd ##查看帮助
可以全部做完有可以重启一下机器看看是否还有Server not Run问题，或者再写一下setenforce 0 重启下Zabbix。
