Note that the MySQL client library is not bundled anymore!
通过查找libmysqlclient,发现是在/usr/lib64/mysql/目录内的libmysqlclient.so.15.0.0做的软连接 ,PHP默认是去的 /usr/lib/搜索,所以没有找到.找到问题了就好解决了.
解决办法就是:
cp -rp /usr/lib64/mysql/libmysqlclient.so.15.0.0 /usr/lib/libmysqlclient.so
centos : --with-mysql=/usr/lib64/mysql (香巴拉) 或者cp /usr/lib64/mysql/* /usr/lib/mysql/
