宝塔安装 PHP 报错 : libcares.so.2: cannot open shared object file: No such file or directory

系统环境 debian或者ubuntu ，宝塔或者mw

直接说解决办法：安装 apt install libc-ares2 ，然后再去宝塔安装就OK了。

下面是解决问题时的过程

报错信息是这样的：

failed to activate:

/www/server/php/72/sbin/php-fpm: error while loading shared libraries: libcares.so.2: cannot open shared object file: No such file or directory

安装 libc-ares2，执行

apt install libc-ares2

然后再去宝塔安装PHP就可以了。

如果你还是安装不上的话，换成下面这个源再试试：
