Zabbix版本升级方案测试，4.0版本升级至5.4版本
注：此方案会导致zabbix的web页面会有一些监控项不兼容现象，只适用于项目平缓过度阶段，后期还是建议agent和server的版本一致。
Zabbix升级方案物理资源
Zabbix升级方案
注意：zabbix server与zabbix proxy版本必须一致，agent可以是低版本。
基础环境配置
| 主机名 | IP | 说明 |
|---|---|---|
| zabbix01 | 192.168.15.201 | zabbix agent 4.0版本 |
| zabbix02 | 192.168.15.202 | zabbix server 4.0版本 |
| zabbix05 | 192.168.15.205 | zabbix proxy 4.0版本 |
| zabbix 03 | 192.168.15.203 | zabbix server 5.4版本 |
| zabbix 04 | 192.168.15.204 | zabbix proxy 5.4版本 |
所有主机的都配置hosts解析
vim /etc/hosts
192.168.15.201 zabbix01
192.168.15.202 zabbix02
192.168.15.205 zabbix05
192.168.15.203 zabbix03
192.168.15.204 zabbix04
安装zabbix server4.0版本
1. 获取zabbix官方源
rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
2. zabbix默认的源默认是在国外的源，将国外的zabbix源地址替换成阿里云的地址
sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
3. 清空缓存
yum clean all
yum makecache
4. 安装zabbix server和agent
yum -y install zabbix-server-mysql zabbix-agent
5. 删除系统默认自带的php5.4版本
rpm -qa |grep php
yum -y remove php* &>/dev/null
rpm -qa |grep php
5.1 更改yum源
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
5.2 安装php7.2版本和各种扩展
yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml
6. 修改zabbix-frontend前端源，开启enabled参数
vim /etc/yum.repos.d/zabbix.repo
[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/$basearch/
enabled=1 # 修改这里
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE59
7. 下载zabbix前端环境
yum install zabbix-web-mysql zabbix-apache-conf -y
8. 在下zabbix所需的数据库，直接用centos自带的mariadb
yum install mariadb-server -y
9. 启动数据库并设置开机自启
systemctl enable --now mariadb
10. 初始化数据库，设置root密码
mysql_secure_installation
# 输入当前root密码(直接回车)
# Enter current password for root (enter for none):
# 设置root密码
# Set root password? [Y/n] y
# New password:
# Re-enter new password:
# 是否移除匿名用户
# Remove anonymous users? [Y/n] y
# 是否禁止root远程登陆
# Disallow root login remotely? [Y/n] n
# 是否移除测试数据库
# Remove test database and access to it? [Y/n] y
# 是否刷新授权表
# Reload privilege tables now? [Y/n] y
11. 使用root用户登陆mariadb，建立zabbix数据库，这里的编码设置，非常重要，否则zabbix无法安装
mysql -uroot -p123
# 创建一个zabbix库，并且设置zabbix的字符编码(utf-8)
create database zabbix character set utf8 collate utf8_bin;
# 创建一个zabbix用户
create user zabbix@localhost identified by '123';
# zabbix用户在zabbix库中的所有表，授予所有的权限
grant all privileges on zabbix.* to zabbix@localhost;
# 刷新授权表
flush privileges;
# 退出
exit
12. 使用zabbix-mysql命令，导入数据库信息
# mysql -u用户名 -p密码 库名
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix
13. 修改zabbix server配置文件，修改数据库的密码
vim /etc/zabbix/zabbix_server.conf
...
DBPassword=123
14. 修改zabbix的php配置文件中的时区
vim /etc/httpd/conf.d/zabbix.conf
...
php_value[date.timezone] = Asia/Shanghai
15. 修改php配置文件
vim /etc/php.ini
...
post_max_size = 500M
max_execution_time = 500
max_input_time = 500
date.timezone = Asia/Shanghai
16. 启动zabbix服务器，设置开机自启
systemctl restart zabbix-server zabbix-agent httpd php-fpm
systemctl enable zabbix-server zabbix-agent httpd php-fpm
安装zabbix proxy 4.0版本
1. 获取zabbix官方源
rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
2. zabbix默认的源默认是在国外的源，将国外的zabbix源地址替换成阿里云的地址
sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
3. 清空缓存
yum clean all
yum makecache
4. 安装proxy 和 数据库
yum -y install zabbix-proxy-mysql zabbix-get mariadb-server mariadb
5. 启动数据库，配置数据库用户，存储zabbix-agent2信息数据
systemctl start mariadb
mysql -uroot -p
create database zabbix_proxy character set utf8 collate utf8_bin;
grant all privileges on zabbix_proxy.* to zabbix@"localhost" identified by "zabbix";
flush privileges;
exit
6. 导入zabbix数据库信息
rpm -ql zabbix-proxy-mysql # 查询sql文件在哪
zcat /usr/share/doc/zabbix-proxy-mysql-4.0.37/schema.sql.gz | mysql -uzabbix -pzabbix zabbix_proxy
7. 修改zabbix-proxy配置文件，链接数据库的信息
sed -i.ori "162a DBPassword=zabbix" /etc/zabbix/zabbix_proxy.conf
sed -i "s#Server=127.0.0.1#Server=192.168.15.202#" /etc/zabbix/zabbix_proxy.conf # 服务端ip
sed -i "s#Hostname=Zabbix proxy#Hostname=zabbix05#" /etc/zabbix/zabbix_proxy.conf # 代理服务器的主机名
8. 检查zabbix-proxy的配置文件信息
grep "^[a-Z]" /etc/zabbix/zabbix_proxy.conf
# Server=192.168.15.202
# Hostname=zabbix05
# LogFile=/var/log/zabbix/zabbix_proxy.log
# LogFileSize=0
# PidFile=/var/run/zabbix/zabbix_proxy.pid
# SocketDir=/var/run/zabbix
# DBPassword=zabbix
# DBName=zabbix_proxy
# DBUser=zabbix
# SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
# Timeout=4
# ExternalScripts=/usr/lib/zabbix/externalscripts
# LogSlowQueries=3000
9. 启动代理服务
systemctl restart zabbix-proxy
安装zabbix agentd4.0版本
1. 获取zabbix官方源
rpm -Uvh https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
2. zabbix默认的源默认是在国外的源，将国外的zabbix源地址替换成阿里云的地址
sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
3. 清空缓存
yum clean all
yum makecache
4. 安装agent2
yum -y install zabbix-agent
5. 查看配置文件和启动命令
# 配置文件
ll /etc/zabbix/zabbix_agentd.conf
# 启动命令
ll /usr/sbin/zabbix_agentd
6. 启动agents并设置开启自启
systemctl enable --now zabbix-agent.service
7. 检查agents的端口号
netstat -lntp | grep agentd
tcp 0 0 0.0.0.0:10050 0.0.0.0:* LISTEN 17507/zabbix_agentd
tcp6 0 0 :::10050 :::* LISTEN 17507/zabbix_agentd
8. 查看systemctl管理的单元文件
cat /lib/systemd/system/zabbix-agent.service
9. 修改agents配置文件，修改如下，添加zabbix-server主机ip和主机名
vim /etc/zabbix/zabbix_agentd.conf
...
Server=192.168.15.205 # 改成proxy地址
ServerActive=192.168.15.205 # 改成proxy地址
Hostname=zabbix01 # 修改成当前客户端的主机名
10. 查看agents配置文件修改后的内容
grep -Ev "^#|^$" /etc/zabbix/zabbix_agentd.conf
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=192.168.15.205
ServerActive=192.168.15.205
Hostname=zabbix01
Include=/etc/zabbix/zabbix_agentd.d/*.conf
11. 重启agent
systemctl restart zabbix-agent.service
