我正在尝试在运行 PHP7 的 Centos7 上安装 Zabbix 3.2。
命令：
yum -y install zabbix-get zabbix-server-mysql zabbix-web-mysql zabbix-agent
输出：
Loaded plugins: fastestmirror, langpacks, replace

尝试使用yum-plugin-replace命令修复
例如：
yum replace php56u-common --replace-with php71u-common
得到这个输出：
Loaded plugins: fastestmirror, langpacks, replace
Replacing packages takes time, please be patient...
Error: Package 'php56u-common' is not installed.
也尝试过（根据此链接）：
yum replace php-common --replace-with php71u-common
并得到这个输出：
Loaded plugins: fastestmirror, langpacks, replace
Replacing packages takes time, please be patient...
Error: Package 'php-common' is not installed
我注意到这些 php56 软件包在执行 a 时没有安装yum list installed，但在执行 a 时确实出现了yum list available。
任何有关如何解决此问题的见解都将受到赞赏。
答案1
尝试这个：
删除所有 PHP 包
yum remove php*
安装 PHP 7.1 软件包：
yum install php71u php71u-cli php71u-common php71u-gd php71u-mbstring php71u-mysqlnd php71u-pdo php71u-xml php71u-json
大功告成，现在检查版本php -v
