Zabbix 4.4安装部署

一、环境准备

环境描述

PHP:72
Nginx 1.16
MySQL 8.0
Zabbix 4.4

1.1：设置阿里镜像源

[root@zabbix-server ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

[root@zabbix-server ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@zabbix-server ~]# yum install epel-release

1.2：关闭SELINUX

[root@zabbix-server ~]# sed -ri 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config 
[root@zabbix-server ~]# setenforce 0
[root@zabbix-server ~]# getenforce 
Permissive

1.3：安装常用软件

[root@zabbix-server ~]# yum -y install bash-completion
[root@zabbix-server ~]# yum -y install bash-completion-extras
[root@zabbix-server ~]# yum -y install vim net-tools wget gcc gcc-devel lrzsz ntp make patch openssl openssl-devel libxml2-devel libxslt-devel perl-devel perl-ExtUtils-Embed libtool zlib zlib-devel pcre pcre-devel

1.4：同步互联网时间

[root@zabbix-server ~]# cp /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime

[root@zabbix-server ~]# ntpdate time1.aliyun.com
[root@zabbix-server ~]# echo "*/5 * * * *  ntpdate time1.aliyun.com &> /dev/null && hwclock -w" >> /var/spool/cron/root

[root@zabbix-server ~]# systemctl  restart crond

1.5：放通zabbix监听端口

#放开端口
[root@zabbix-server ~]# firewall-cmd --permanent --zone=public --add-port=10050/tcp
[root@zabbix-server ~]# firewall-cmd --permanent --zone=public --add-port=10051/tcp

[root@zabbix-server ~]# firewall-cmd --permanent --zone=public --add-port=80/tcp

#使其规则生效
[root@zabbix-server ~]# firewall-cmd --reload
 
#查看端口是否放开
[root@zabbix-server ~]# firewall-cmd --list-port
10050/tcp 10051/tcp 80/tcp

二、部署原文链接：https://www.dqzboy.comNginx

2.1：安装

使用RPM包进行安装

[root@zabbix-server ~]# mkdir /soft
[root@zabbix-server ~]# cd /soft/
[root@zabbix-server soft]# wget http://nginx.org/packages/centos/7/x86_64/RPMS/nginx-1.16.1-1.el7.ngx.x86_64.rpm

[root@zabbix-server soft]# rpm -ivh nginx-1.16.1-1.el7.ngx.x86_64.rpm

[root@zabbix-server ~]# nginx -v
nginx version: nginx/1.16.1

2.2：启动

[root@zabbix-server ~]# systemctl start nginx
[root@zabbix-server ~]# systemctl enable nginx
[root@zabbix-server ~]# systemctl status nginx

2.3：访问

三、部署MySQL

安装新版MySQL8.0版本

3.1：下载YUM源

[root@zabbix-server ~]# wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm

3.2：安装YUM源

[root@zabbix-server ~]# rpm -ivh mysql80-community-release-el7-3.noarch.rpm

3.3：安装服务端

# 查看 mysql server
[root@zabbix-server ~]# yum repolist enabled | grep "mysql.*-community.*"
[root@zabbix-server ~]# yum repolist all | grep mysql

# 安装
[root@zabbix-server ~]# yum install mysql-community-server

3.4：启动服务

[root@zabbix-server ~]# systemctl start mysqld.service
[root@zabbix-server ~]# systemctl enable mysqld.service
[root@zabbix-server ~]# systemctl status mysqld.service

3.5：密码配置

3.5.1：查看登陆密码

[root@zabbix-server ~]# cat /var/log/mysqld.log | grep 'password'

3.5.2：登陆

[root@zabbix-server ~]# mysql -uroot -p

到这里 MySQL 就完全安装完成了

3.5.3：重置密码

# 密码验证策略低要求
mysql> set global validate_password.policy=0; (0或LOW代表低级)

# 密码至少要包含的小写字母个数和大写字母个数
mysql> set global validate_password.mixed_case_count=0;

# 密码至少要包含的数字个数。
mysql> set global validate_password.number_count=0; 

# 密码至少要包含的特殊字符数
mysql> set global validate_password.special_char_count=0; 

# 密码长度
mysql> set global validate_password.length=4;  #8.0最小长度为4

# 再次设置密码
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'dqz123';

3.6：创建用户和数据库

# 创建数据库
[root@zabbix-server ~]# mysql -uroot -p
mysql> create database zabbix character set utf8 collate utf8_bin;

# 创建zabbix账号；MySQL8.0的账号身份验证和MySQL5.7不同
mysql> create user zabbix@localhost identified with mysql_native_password by 'dqz123';

# 授权
mysql> grant all privileges on zabbix.* to zabbix@localhost;

四、部署PHP

4.1：安装

[root@zabbix-server ~]# yum install epel-release
[root@zabbix-server ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

[root@zabbix-server ~]# yum install php72w-fpm php72w-opcache

4.2：配置

[root@zabbix-server ~]# vim /etc/php.ini
368 max_execution_time = 300	//默认30,Zabbix要求为300
378 max_input_time = 300		//默认60
385 max_input_vars = 10000	//去除注释，默认1000改为10000
389 memory_limit = 128M		//内存限制
656 post_max_size = 16M		//默认8M改为16M
877 date.timezone = Asia/Shanghai   //去除注释，默认空，更为为上海时区

# 修改用户
[root@zabbix-server ~]# vim /etc/php-fpm.d/www.conf
8 user = nginx
10 group = nginx

[root@zabbix-server ~]# chown -R nginx. /var/lib/php

4.3：启动

[root@zabbix-server ~]# systemctl start php-fpm
[root@zabbix-server ~]# systemctl enable php-fpm

五、安装Zabbix-server

5.1：添加Zabbix镜像源

[root@zabbix-server ~]# rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm
[root@zabbix-server ~]# yum clean all

注：安装时有可能被墙导致安装失败，可替换官方源地址，将官方地址改为清华源的地址

[root@zabbix-server ~]# vim /etc/yum.repos.d/zabbix.repo
# 末行模式输入以下进行替换
:%s#http://repo.zabbix.com/zabbix/4.4/rhel/7/#https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.4/rhel/7/#g

5.2：安装zabbix-server

#安装服务端，前端，和agent
[root@zabbix-server ~]# yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-nginx-conf

5.3：配置zabbix数据库

#导入数据
[root@zabbix-server ~]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
Enter password:	//zabbix用户密码

#编辑配置文件
[root@zabbix-server ~]# vim  /etc/zabbix/zabbix_server.conf
91 DBHost=localhost    //去除注释
100 DBName=zabbix		//数据库名称
116 DBUser=zabbix		//用户
124 DBPassword=123456	//去除注释，输入数据库用户zabbix的密码

# 以下解决报警：Zabbix discoverer processes more than 75% busy问题
189 StartPollers=12  //去除注释，增加初始化进程，默认5
244 StartDiscoverers=5  //去除注释，增加discovery进程数量，默认1

5.4：启动Za文章来源(Source)：https://www.dqzboy.combbix Serve文章来源(Source)：浅时光博客r

[root@zabbix-server ~]# systemctl  start zabbix-server.service
[root@zabbix-server ~]# systemctl  enable zabbix-server.service
[root@zabbix-server ~]# systemctl  status zabbix-server.service

5.5：检查日志是否有报错

[root@zabbix-server ~]# more /var/log/zabbix/zabbix_server.log

5.6：配置zabbix-web

将nginx默认调用的外部配置文件重命名，这样就直接调用zabbix的配置文件了

[root@zabbix-server ~]# cd /etc/nginx/conf.d/
[root@zabbix-server conf.d]# mv default.conf{,_bak}

zabbix.conf配原文链接：https://www.dqzboy.com置文件内容如下

server {
#        listen          80;
#        server_name     example.com;

                fastcgi_temp_file_write_size    256k;
        }
}

5.7：重新启动服务

[root@zabbix-server ~]# systemctl restart zabbix-server zabbix-agent nginx php-fpm
[root@zabbix-server ~]# systemctl enable zabbix-server zabbix-agent nginx php-fpm
