5、启动 Zabbix 进程

systemctl start zabbix-server
systemctl start zabbix-proxy
systemctl start zabbix-agent
systemctl start zabbix-agent2

一般到此处已经升级完成，但是此次版本升级连带着mysql数据也升级了，就会出现如下报错

tail -f /var/log/zabbix/zabbix_server.log

query failed: [1419] You do not have the SUPER privilege and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable) 
[create trigger proxy_insert after insert on proxy

mysql> SHOW VARIABLES LIKE 'log_bin_trust_function_creators';

mysql> SET GLOBAL log_bin_trust_function_creators = 1;

systemctl restart zabbix-server.service
