Zabbix4.0

1、部署环境

系统：CentOS7.8(内核3.10)
Zabbix版本：4.0
MySQL版本：8.0
Apache(httpd)版本：2.4.6

2、部署前准备

2.1、升级系统组件到最新版本

yum -y update       

2.2、关闭selinux

# 临时关闭
setenforce 0
# 永久关闭
vim /etc/selinux/config
    ......
    SELINUX=disabled
    ......

2.3、关闭防火墙

# 若是可以开启相关的端口，可以选择不关闭防火墙
systemctl stop firewalld

2.4、添加Zabbix、MySQL源

# 添加MySQL Yum源
wget  https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm
rpm -ivh mysql80-community-release-el7-1.noarch.rpm
yum clean all
yum makecache
# yum repolist all | grep mysql
# yum-config-manager --disable mysql57-community(关闭5.7版本)
# yum-config-manager --enable mysql80-community(开启8.0版本)
--------------------------------
# 添加Zabbix Yum源
cd /etc/yum.repos.d/
vim zabbix.repo
    [zabbix]
    name=Zabbix Official Repository - $basearch
    #baseurl=http://repo.zabbix.com/zabbix/3.4/rhel/7/$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

3、构建LAMP环境

3.1、部署MySQL环境

# 安装MySQL
yum install mysql-community-server
systemctl start mysqld
# 修改密码
cat /var/log/mysqld.log | grep password  # 获取初始root密码
mysql -uroot -p 
    > ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!'
--------------------------------
# Mysql8.0设置密码过于简单解决方法：
> show variables like 'validate_password%';
> set global validate_password.policy=0;
> set global validate_password.length=1;

# 创建Zabbix数据库，以及zabbix用户
> create database zabbix character set utf8 collate utf8_bin;
> grant all on zabbix.* to 'zabbix'@'%' identified by 'ykadmin123';
> flush privileges;

# 删除MySQL空用户
> drop user ''@localhost;
> drop user ''@localhost.localdomain;

3.2、部署Apache环境

yum -y install httpd
systemct start httpd
# 配置httpd
vim /etc/httpd/conf/httpd.conf
    ......
    ServerName www.xxxx.com # 可修改域名，此处使用ip访问，所以没有动
    DirectoryIndex index.html index.php # 添加支持php格式
    ......
systemctl restart httpd

3.3、部署PHP环境

yum install -y php php-mysql php-gd libjpeg* php-ldap php-odbc php-pear php-xml php-xmlrpc php-mhash
# 配置PHP环境
vim /etc/php.ini
    ......
    date.timezone = PRC # 设置时区
    ......

4、安装Zabbix

4.1、安装依赖包、组件

yum -y install net-snmp net-snmp-devel curl curl-devel libxml2 libxml2-devel libevent-devel.x86_64 javacc.noarch  javacc-javadoc.noarch javacc-maven-plugin.noarch javacc*

4.2、安装Zabbbix

# 安装php支持zabbix的组件
yum -y install php-bcmath php-mbstring 

# 安装Zabbix
yum -y install zabbix-server-mysql zabbix-web-mysql

# 导入Zabbix初始数据
zcat /usr/share/doc/zabbix-server-mysql-4.0.0/create.sql.gz | mysql -uzabbix -p zabbix

4.3、修改Zabbix配置

# Zabbix连接数据库设置
vim /etc/zabbix/zabbix_server.conf
    ......
    DBName=zabbix
    DBUser=zabbix
    DBPassword=ykadmin123
    ......

# Zabbix时区设置
vim /etc/httpd/conf.d/zabbix.conf
    ......
    将# php_value date.timezone Europe/Riga 变更成php_value date.timezone Asia/Shanghai
    ......
    
systemctl restart zabbix-server 

5、Web安装Zabbix

浏览器访问地址：http://xxx.xxx.xxx.xxx/zabbix

6、安装时的坑

6.1、缺少libiksemel.so.3依赖

# 安装Zabbix时缺少libiksemel.so.3依赖
wget  http://springdale.math.ias.edu/data/puias/unsupported/7/x86_64//iksemel-1.4-6.sdl7.x86_64.rpm
yum install iksemel-1.4-6.sdl7.x86_64.rpm

6.2、无法连接数据库

# Zabbix安装成功后遇到加密问题，无法登录数据库caching_sha2_password
tail -f /var/log/zabbix/zabbix_server.log
    ......
    Details Cannot connect to the database.
Error connecting to database: Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/lib64/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory
    ......
# 修改加密规则  
> ALTER USER 'zabbix'@'%' IDENTIFIED BY 'ykadmin123' PASSWORD EXPIRE NEVER; 
# 更新密码（mysql_native_password模式）    
> ALTER USER 'zabbix'@'%' IDENTIFIED WITH mysql_native_password BY 'ykadmin123';

6.3、中文字体乱码

windows字体位置：控制面板 -> 外观和个性化 -> 字体
将字体上传至/usr/share/zabbix/assets/fonts下

修改Zabbix配置文件

# 修改以下内容
vim /usr/share/zabbix/include/defines.inc.php
    .....
    define('ZBX_GRAPH_FONT_NAME',       'graphfont');
    .....
    define('ZBX_FONT_NAME', 'graphfont');
    .....
    # 将以上两行内的graphfont修改为上传字体名称(不需要加后缀)

Zabbix5.0

1、部署环境

系统：CentOS7.5(内核3.10)
Zabbix版本：5.0
MySQL版本：5.0

2、部署前准备

2.1、安装Zabbix源

# 下载Zabbix源
rpm -ivh https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
# 替换源
sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
# 更新
yum clean all && yum makecache

2.2、安装Zabbix

yum -y install zabbix-server-mysql zabbix-agent 
yum install -y centos-release-scl
# 安装Zabbix前端包
yum -y install zabbix-web-mysql-scl zabbix-nginx-conf-scl

2.3、安装MySQL

# MySQL已经安装好
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@'%' identified by 'rootroot';
mysql> flush privileges;

2.4、导入Zabbix的表

zcat /usr/share/doc/zabbix-server-mysql-5.0.22/create.sql.gz | mysql -uzabbix -p zabbix

2.5、修改Zabbix配置(与4.0配置一致)

2.6、修改前段配置PHP

# 编辑文件 /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf，取消注释并设置 'listen'指令
# listen 80;
listen 10088;

# 编辑文件 /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf，将 nginx 添加到 listen.acl_users 指令中
listen.acl_users = apache,nginx

# 修改时区
vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
php_value[date.timezone] = Asia/Shanghai

2.7、启动

systemctl restart zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
systemctl enable zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
