libmysqlclient.so.16: cannot open shared object file: No such file or directory

编译安装的mysql5.6.39，安装目录是/usr/local/mysql，启用程序时报错：libmysqlclient.so.16: cannot open shared object file: No such file or directory。检查mysql的.so库文件，发现有libmysqlclient.so.18，而程序启用依赖的mysql库文件是libmysqlclient.so.16。解决办法：

解决思路：
使用yum安装mysql，然后启用libmysqlclient.so.16的库文件！

解决过程：
[root@back-server ~]# ldconfig -v |grep mysql
ldconfig: /etc/ld.so.conf.d/kernel-2.6.32-696.el6.x86_64.conf:6: duplicate hwcap 1 nosegneg
ldconfig: Can't open directory /usr/local/lib/libpcre.so.1: Not a directory
/usr/local/mysql/lib:
        libmysqlclient.so.18 -> libmysqlclient_r.so.18.1.0
        libauthmysql.so -> libauthmysql.so.0


[root@back-server ~]# ll /usr/local/mysql/lib/

drwxr-xr-x 3 mysql mysql      4096 Jul 27 11:55 plugin

[root@back-server ~]# cat /etc/ld.so.conf
......
/usr/loca/mysql/lib

现在使用yum安装mysql
[root@back-server ~]# yum install -y mysql
[root@back-server ~]# ldconfig -v |grep mysql
ldconfig: /etc/ld.so.conf.d/kernel-2.6.32-696.el6.x86_64.conf:6: duplicate hwcap 1 nosegneg
ldconfig: Can't open directory /usr/local/lib/libpcre.so.1: Not a directory
/usr/lib64/mysql:
        libmysqlclient.so.16 -> libmysqlclient.so.16.0.0
        libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0
/usr/local/mysql/lib:
        libmysqlclient.so.18 -> libmysqlclient_r.so.18.1.0
        libauthmysql.so -> libauthmysql.so.0

启用libmysqlclient.so.16库文件
[root@back-server ~]# cat /etc/ld.so.conf
.....
/usr/lib64/mysql
[root@back-server ~]# ldconfig 

再次查看
[root@back-server ~]# ldconfig -v |grep mysql
ldconfig: /etc/ld.so.conf.d/kernel-2.6.32-696.el6.x86_64.conf:6: duplicate hwcap 1 nosegneg
ldconfig: Can't open directory /usr/local/lib/libpcre.so.1: Not a directory
/usr/lib64/mysql:
        libmysqlclient.so.16 -> libmysqlclient.so.16.0.0
        libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0
