一、官网查询zabbix5.0 升级7.0需要逐步升级
1 官网地址：
https://www.zabbix.com/documentation/current/en/manual/installation/upgrade
2 查看zabbix各个版本对mariadb、Nginx、php版本的最低需求（升级前需先确认mariadb、Nginx、php版本是否满足需求，如不满足请先升级官方建议版本，升级方法后面介绍）
https://www.zabbix.com/documentation/current/en/manual/installation/requirements
二、zabbix5.0升级至5.2(注意所有更新前请确保系统时间正确)
1 Stop Zabbix processes
Stop Zabbix server to make sure that no new data is inserted into database.
# service zabbix-server stopIf upgrading Zabbix proxy, stop proxy too.
# service zabbix-proxy stop2 Back up the existing Zabbix database
This is a very important step. Make sure that you have a backup of your database. It will help if the upgrade procedure fails (lack of disk space, power off, any unexpected problem).
3 Back up configuration files, PHP files and Zabbix binaries
Make a backup copy of Zabbix binaries, configuration files and the PHP file directory.
Configuration files:
mkdir /opt/ /etc/zabbix/nginx.confzabbix-backup/
cp /etc/zabbix/zabbix_server.conf /opt/zabbix-backup/
cp /etc/zabbix/nginx.conf /opt/zabbix-backup/PHP files and Zabbix binaries:
cp -R /usr/share/zabbix/ /opt/zabbix-backup/
cp -R /usr/share/doc/zabbix-* /opt/zabbix-backup/4 Update repository configuration package
To proceed with the update your current repository package has to be uninstalled.
rm -Rf /etc/apt/sources.list.d/zabbix.listThen install the new repository configuration package.
On Debian 10 run:
wget https://repo.zabbix.com/zabbix/5.2/debian/pool/main/z/zabbix-release/zabbix-release_5.2-1+debian10_all.deb
dpkg -i zabbix-release_5.2-1+debian10_all.debOn Debian 9 run:
# wget https://repo.zabbix.com/zabbix/5.2/debian/pool/main/z/zabbix-release/zabbix-release_5.2-1+debian9_all.deb# dpkg -i zabbix-release_5.2-1+debian9_all.debOn Debian 8 run:
# wget https://repo.zabbix.com/zabbix/5.2/debian/pool/main/z/zabbix-release/zabbix-release_5.2-1+debian8_all.deb# dpkg -i zabbix-release_5.2-1+debian8_all.debOn Ubuntu 20.04 run:
# wget https://repo.zabbix.com/zabbix/5.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.2-1+ubuntu20.04_all.deb# dpkg -i zabbix-release_5.2-1+ubuntu20.04_all.debOn Ubuntu 18.04 run:

# wget https://repo.zabbix.com/zabbix/5.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.2-1+ubuntu16.04_all.deb# dpkg -i zabbix-release_5.2-1+ubuntu16.04_all.debOn Ubuntu 14.04 run:
# wget https://repo.zabbix.com/zabbix/5.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.2-1+ubuntu14.04_all.deb# dpkg -i zabbix-release_5.2-1+ubuntu14.04_all.debUpdate the repository information.
# apt-get update5 Upgrade Zabbix components
To upgrade Zabbix components you may run something like:
# apt-get install --only-upgrade zabbix-server-mysql zabbix-frontend-php zabbix-agent6 Review component configuration parameters
See the upgrade notes for details on mandatory changes.
For new optional parameters, see the What's new section.
7 Start Zabbix processes
Start the updated Zabbix components.
service zabbix-server start
service zabbix-proxy start8 Clear web browser cookies and cache
After the upgrade you may need to clear web browser cookies and web browser cache for the Zabbix web interface to work properly.
三、zabbix5.2 ->5.4 ->6.0 ->6.2 ->6.4 ->7.0， 同二步骤，只是需在第4小点更新存储库配置包, 其余操作相同
1 zabbix5.4
On Ubuntu 20.04 run:
wget https://repo.zabbix.com/zabbix/5.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.4-1+ubuntu20.04_all.deb
dpkg -i zabbix-release_5.4-1+ubuntu20.04_all.deb2 zabbix6.0
On Ubuntu 20.04 run:
wget https://repo.zabbix.com/zabbix/6.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.0-1+ubuntu20.04_all.deb
dpkg -i zabbix-release_6.0-1+ubuntu20.04_all.deb3 zabbix6.2
On Ubuntu 20.04 run:
wget https://repo.zabbix.com/zabbix/6.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.2-1+ubuntu20.04_all.deb
dpkg -i zabbix-release_6.2-1+ubuntu20.04_all.deb4 zabbix6.4
On Ubuntu 22.04 run:
wget https://repo.zabbix.com/zabbix/6.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.4-1+ubuntu22.04_all.deb
dpkg -i zabbix-release_6.4-1+ubuntu22.04_all.deb5 zabbix7.0
On Ubuntu 24.04, run:
wget https://repo.zabbix.com/zabbix/7.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest+ubuntu24.04_all.deb
dpkg -i zabbix-release_latest+ubuntu24.04_all.debOn Ubuntu 22.04, run:
wget https://repo.zabbix.com/zabbix/7.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest+ubuntu22.04_all.deb
dpkg -i zabbix-release_latest+ubuntu22.04_all.deb四、mariadb升级方法
1 、备份zabbix数据库，历史数据除外
mysqldump -uroot -pzabbix --databases zabbix \
--ignore-table=zabbix.history \
--ignore-table=zabbix.history_uint \
--ignore-table=zabbix.history_str \
--ignore-table=zabbix.history_text \
--ignore-table=zabbix.trends \
> zabbix_backup.sql2、停止运行数据库
sytemctl stop mariadb3、卸载当前版本MariaDB
remove mariadb mariadb-server4、添加MariaDB的apt源，到官网查询相关原地址
https://mariadb.org/download/?t=repo-config&d=20.04+%22focal%22&v=10.5&r_m=aliyun
Here are the commands to run to import the MariaDB repository key on your Ubuntu system:
sudo apt-get install apt-transport-https curl
sudo mkdir -p /etc/apt/keyrings
sudo curl -o /etc/apt/keyrings/mariadb-keyring.pgp 'https://mariadb.org/mariadb_release_signing_key.pgp'Once the key is imported, copy and paste the following into a file under /etc/apt/sources.list.d (for instance /etc/apt/sources.list.d/mariadb.sources):
# MariaDB 10.5 repository list - created 2024-07-25 04:00 UTC
# https://mariadb.org/download/
X-Repolib-Name: MariaDB
Types: deb
# deb.mariadb.org is a dynamic mirror if your preferred mirror goes offline. See https://mariadb.org/mirrorbits/ for details.
# URIs: https://deb.mariadb.org/10.5/ubuntu
URIs: https://mirrors.aliyun.com/mariadb/repo/10.5/ubuntu
Suites: focal
Components: main main/debug
Signed-By: /etc/apt/keyrings/mariadb-keyring.pgpYou can now install MariaDB 10.5 from the MariaDB repository with:
sudo apt-get update
sudo apt-get install mariadb-server5、升级完成以后启动数据库，设置开机启动数据库
systemctl start mariadb
systemctl enable mariadb.service五、Nginx升级方法
1、备份配置文件
cp /etc/nginx/nginx.conf /backup2、停止nginx服务器
systemctl stop nginx.service3、卸载旧nginx版本
apt-get --purge remove nginx4、Nginx官网
https://nginx.org/en/download.html
Mainline version：正在开发阶段的版本，可能会有bug。
Stable version：稳定版
Legacy versions： 历史版本
本次安装1.18.0的稳定版本
5、Nginx安装
安装或升级，需要添加源才能下载 Nginx 的稳定版本，首先输入以下两条命令：
sudo wget http://nginx.org/keys/nginx_signing.key
sudo apt-key add nginx_signing.key在 `/etc/apt/sources.list` 文件中加入下面两行：
deb http://nginx.org/packages/ubuntu/ code nginx
deb-src http://nginx.org/packages/ubuntu/ code nginx其中code 要根据系统来选择，20.04环境code=focal
deb http://nginx.org/packages/ubuntu/ nginx
deb-src http://nginx.org/packages/ubuntu/ code nginxhttps://nginx.org/en/linux_packages.html#Ubuntu
运行如下命令
sudo apt-get update
sudo apt-get install nginx最后查看版本是否升级成功
root@zabbix-01:~# nginx -v
nginx version: nginx/1.24.0 (Ubuntu)六、PHP升级方法
1、修改系统为正确时间
date -s "2024-07-24 14:43:25"2、安装扩展及更新源
apt install -y software-properties-common
add-apt-repository ppa:ondrej/nginx-mainline（根据自己装Apache或Nginx调整）
apt update
3、查看php扩展
dpkg -l | grep php | tee packages.txt4、安装php8.3及扩展
apt-get install php8.3
apt-get install php8.3-fpm php8.3-bcmath php8.3-xml php8.3-mbstring php8.3-mysql php8.3-ldap php8.3-opcache
apt-get isntall php8.3-json5、注册php路径
update-alternatives --install /usr/bin/php php /usr/bin/php8.3 83
update-alternatives --config php6、查看路径
ls -al /etc/alternatives/php-fpm.sock
7、修改Nginx配置文件
vim /etc/zabbix/nginx.conf
fastcgi_pass unix:/var/run/php/zabbix.sock;（将zabbix.sock修改为php-fpm.sock）
8、重启Nginx
systemctl restart nginx.service七、Zabbix小版本升级
It is possible to upgrade minor versions of 7.0.x (for example, from 7.0.1 to 7.0.3)
To upgrade Zabbix minor version please run:
sudo apt-get install --only-upgrade 'zabbix.*'To upgrade Zabbix server minor version please run:
sudo apt-get install --only-upgrade 'zabbix-server.*'To upgrade Zabbix agent minor version please run:
sudo apt-get install --only-upgrade 'zabbix-agent.*'or, for Zabbix agent 2:
sudo apt-get install --only-upgrade 'zabbix-agent2.*'
