php: error while loading shared libraries: libonig.so.2

1、故障背景：
CentOS7 执行yum -y update 命令升级系统后，起初测试正常，在执行“php -V”测试报如下错误：

php: error while loading shared libraries: libonig.so.2: cannot open shared object file: No such file or directory

2.执行以下命令

ln -s /usr/lib64/libonig.so /usr/lib64/libonig.so.2
