centos7.5zabbix4.0升级到zabbix5.0

 

1 更新yum源
# yum erase zabbix-release-4.0-1.el7.noarch
# rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm
# sed -i 's#http://repo.zabbix.com#https://mirrors.aliyun.com/zabbix#' /etc/yum.repos.d/zabbix.repo
 
2 开启前端服务
# vim /etc/yum.repos.d/zabbix.repo
[zabbix-frontend]
name=Zabbix Official Repository frontend - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/5.0/rhel/7/$basearch/frontend
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
 
3 停止zabbix服务
# yum clean all
# yum list | grep zabbix
# systemctl stop httpd
# systemctl stop zabbix-server.service
# systemctl stop zabbix-agent.service 
 
4 升级zabbix服务
# yum upgrade zabbix-server-mysql zabbix-web-mysql zabbix-agent
 
5 升级zabbix前端
# yum remove zabbix-web
# yum install centos-release-scl -y
# yum install zabbix-web-mysql-scl zabbix-apache-conf-scl -y
 
6 修改php时区
# vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
php_value[date.timezone] = Asia/shanghai
 
7 启动zabbix并设置开机自启动
# systemctl start zabbix-server zabbix-agent httpd rh-php72-php-fpm
# systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm
 
8 为mysql打补丁(因为Zabbix的历史数据和趋势数据的数值（浮点型）数据类型支持的精度更高)
# wget https://git.zabbix.com/projects/ZBX/repos/zabbix/raw/database/mysql/double.sql
# cat double.sql
ALTER TABLE trends
    MODIFY value_min DOUBLE PRECISION DEFAULT '0.0000' NOT NULL,
    MODIFY value_avg DOUBLE PRECISION DEFAULT '0.0000' NOT NULL,
    MODIFY value_max DOUBLE PRECISION DEFAULT '0.0000' NOT NULL;
ALTER TABLE history MODIFY value DOUBLE PRECISION DEFAULT '0.0000' NOT NULL;
 
# mysql -uroot -p
MariaDB [(none)]> use zabbix;
MariaDB [zabbix]> ALTER TABLE trends
    MODIFY value_min DOUBLE PRECISION DEFAULT '0.0000' NOT NULL,
    MODIFY value_avg DOUBLE PRECISION DEFAULT '0.0000' NOT NULL,
    MODIFY value_max DOUBLE PRECISION DEFAULT '0.0000' NOT NULL;
MariaDB [zabbix]> ALTER TABLE history MODIFY value DOUBLE PRECISION DEFAULT '0.0000' NOT NULL;
MariaDB [zabbix]> exit;
 
更新配置文件，添加如下内容
# vim /etc/zabbix/web/zabbix.conf.php
$DB['DOUBLE_IEEE754'] = true;
 
9 重启zabbix-server
# systemctl restart zabbix-server

10 升级后注意个组件版本

[root@localhost ~]# rpm -qa|grep zabbix
