报错 libmysqlclient.so.20: cannot open shared object file: No such file or directory

1 背景

环境：centos7，c++程序

最近在重新部署一个老软件都时候遇到 libmysqlclient.so.20: cannot open shared object file: No such file or directory 错误，这是提示缺失mysql的连接文件

2 解决方法

错误提示已经很明显了，那就缺啥补啥，找一台装过mysql的机器查找此文件

[root@localhost ~]# find / -name libmysqlclient.so.20
/usr/lib64/mysql/libmysqlclient.so.20

将文件拷贝至机器

[root@localhost ~]# scp /usr/lib64/mysql/libmysqlclient.so.20 192.168.1.13:/usr/lib64/mysql/libmysqlclient.so.20

修改配置

[root@pg-1 sdhFusionServer]# vi /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/lib64/mysql/

reload配置

ldconfig

再重启程序，解决收工
