一、查看当前各软件版本号

OS层面

内核版本为2.6.32，64bit

应用层面

业务层面

[root@vm172-31-0-21 share]# zabbix_server -V
zabbix_server (Zabbix) 3.0.30

二、备份

1、备份数据库

数据库全备时间比较长且文件交大，建议压缩或者使用xtrabackup， 此处采用mysqldump。

mysqldump -uzabbix -pzabbix  --opt --skip-lock-tables --database zabbix | gzip > zabbix_`date +'%Y%m%d%H%M%S'`.sql.gz

　　

 

2、备份应用配置

mkdir /data/web-backup/  #创建一个空文件
cp /etc/php.ini  /data/web-backup/  #PHP配置文件
cp /etc/php-fpm.d/www.conf  /data/web-backup/  #PHP-fpm配置文件
cp /etc/nginx/nginx.conf  /data/web-backup/  #Nginx配置文件

　　

3、备份业务配置

mkdir /data/zabbix-backup/  #创建一个空文件
cp /etc/zabbix/zabbix_server.conf /data/zabbix-backup/
cp -R /usr/share/zabbix/ /data/zabbix-backup/
cp -R /usr/share/doc/zabbix-* /data/zabbix-backup/

　　

三、升级Zabbix

1、停止服务

service zabbix-server stop
service zabbix-agent stop
service nginx stop

　　

2、升级zabbix源

rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/6/x86_64/zabbix-release-4.0-2.el6.noarch.rpm

　　

3、升级zabbix

 

yum clean all
yum upgrade  zabbix-sender zabbix-agent zabbix-proxy-mysql  zabbix-java-gateway

 

　　

 

　　

注意：由于centOS6在zabbix4.0版本上无法直接yum upgrade，有些包在yum仓库里面放入了deprecated文件，具体原因也未知，所以需要下载下来进行安装。

 

 

 可以直接一键升级：

rpm -Uvh  zabbix-server-mysql-4.0.18-1.el6.x86_64.rpm  zabbix-web-4.0.18-1.el6.noarch.rpm  zabbix-web-mysql-4.0.18-1.el6.noarch.rpm

　　

4、启动服务

service zabbix-server start
service zabbix-agent start
service nginx start

　　

5、升级后验证

 

 

 

 

 

 

6、升级过程中遇到的问题

a、curl: (35) SSL connect error

 

 解决方式：

yum -y update nss
ldconfig

　

 

b、libevent-1.4.so.2()(64bit) is needed by zabbix-proxy-mysql-4.0.18-1.el6.x86_64

 

 

 c、升级rpm包

rpm -Uvh zabbix-web-4.0.18-1.el6.noarch.rpm   zabbix-web-mysql-4.0.18-1.el6.noarch.rpm

 

 

rpm -Uvh zabbix-server-mysql-4.0.18-1.el6.x86_64.rpm 

 

d、字体修改

yum install wqy-microhei-fonts -y

cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /usr/share/zabbix/assets/fonts/graphfont.ttf
