[root@test-huanqiu ~]# yum -y install perl-DBD-MySQL.x86_64
……
Package perl-DBD-MySQL-4.013-3.el6.x86_64 already installed and latest version //发现本机已经安装了
[root@test-huanqiu ~]# rpm -qa|grep perl-DBD-MySQL
perl-DBD-MySQL-4.013-3.el6.x86_64
发现本机已经安装了最新版的perl-DBD-MYSQL了,但是仍然报出上面的错误!! 莫慌~~继续下面的操作进行问题的解决
查看mysql.so依赖的lib库
[root@test-huanqiu ~]# ldd /usr/lib64/perl5/auto/DBD/mysql/mysql.so
linux-vdso.so.1 => (0x00007ffd291fc000)

libselinux.so.1 => /lib64/libselinux.so.1 (0x00007f78fd15a000)
以上结果说明缺少libmysqlclient.so.16这个二进制包,找个官方原版的mysql的libmysqlclient.so.16替换了即可!
[root@test-huanqiu~]# find / -name libmysqlclient.so.16 //查看本机并没有libmysqlclient.so.16库文件
查看mysql/lib下的libmysqlclinet.so库文件
[root@test-huanqiu~]# ll /usr/local/mysql/lib/

将mysql/lib/libmysqlclient.so.18.1.0库文件拷贝到/lib64下,拷贝后命名为libmysqlclient.so.16
[root@test-huanqiu~]# cp /usr/local/mysql/lib/libmysqlclient.so.18.1.0 /lib64/libmysqlclient.so.16
[root@test-huanqiu~]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf

/lib64/
[root@test-huanqiu~]# ldconfig
