背景:等保3級測評，zabbix4.0 自帶的PHP版本5.4.16 存在漏洞，要求整改

1、現有版本檢視

2、準備YUM源

yum -y install  epel-release yum-utils
yum install -y  http://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum-config-manager --disable remi-php54 #禁用php54
yum-config-manager --enable remi-php73  #啟用php74

3、安裝依賴

rpm -Uvh http://mirror.centos.org/centos/7/os/x86_64/Packages/graphite2-1.3.10-1.el7_3.x86_64.rpm
 

rpm -Uvh http://mirror.centos.org/centos/7/os/x86_64/Packages/harfbuzz-1.7.5-2.el7.x86_64.rpm
rpm -Uvh http://mirror.centos.org/centos/7/os/x86_64/Packages/fribidi-1.0.2-1.el7_7.1.x86_64.rpm
rpm -Uvh https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libraqm-0.7.0-4.el7.x86_64.rpm

 3、正式升級php

systemctl stop httpd
yum update php
 
*
systemctl start httpd

#如果如題如下錯誤，請手動安裝一下依賴

rpm -Uvh https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libsodium-1.0.18-1.el7.x86_64.rpm

4、zabbix頁面報錯處理：

#能正常登入的，只是報PHP配置錯誤，根據提示修改/etc/php.ini檔案，重啟httpd即可
