查看crond状态发现有告警

Apr 08 11:48:31 DNSSERVER01 crond[3460]: /usr/sbin/sendmail: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory

发现缺少libmysqlclient.so.18

[root@DNSSERVER01 network-scripts]# cd /usr/lib
[root@DNSSERVER01 lib]# ls libmysqlclient*
ls: cannot access libmysqlclient*: No such file or directory
[root@DNSSERVER01 lib]# ls /usr/local/mysql/lib/libmysqlclient.so.18
ls: cannot access /usr/local/mysql/lib/libmysqlclient.so.18: No such file or directory
[root@DNSSERVER01 lib]# ls /usr/local/mysql/lib/libmysqlclient*
/usr/local/mysql/lib/libmysqlclient.a /usr/local/mysql/lib/libmysqlclient.so /usr/local/mysql/lib/libmysqlclient.so.20 /usr/local/mysql/lib/libmysqlclient.so.20.3.11

发现自己系统里的是libmysqlclient.so.20

做软连接
[root@DNSSERVER01 lib]# ln -s /usr/local/mysql/lib/libmysqlclient.so.20 /usr/lib
[root@DNSSERVER01 lib]# service crond restart
Redirecting to /bin/systemctl restart crond.service
