You are not able to choose some of the languages, because locales for them are not installed on the web server.
1、安装wget
yum -y install wget
2、下载中文中文字体并配置
wget https://github.com/echohn/zabbix-zh_CN/archive/master.zip
yum -y install unzip
unzip master.zip
rm frontend.mo
cp zabbix-zh_CN-master/frontend.mo frontend.mo
3、下载中文语言包并识别
yum -y install langpacks-zh_CN.noarch
yum -y reinstall glibc-common
locale -a | grep zh_CN #确认安装成功
4、重启apache&zabbix_server两个服务
service zabbix-server restart
5、回到web页面刷新可以看到中文语言已经可以选择
