# credential example
install -m 600 %{_sourcedir}/mysql_backup/config/ldmgr.cnf \
    %{buildroot}/etc/mysql_backup/.ldmgr.cnf


========================================
正确格式（必须紧贴）
正确写法：
install -m 600 %{_sourcedir}/mysql_backup/config/ldmgr.cnf \
    %{buildroot}/etc/mysql_backup/.ldmgr.cnf
注意：
\ 后 不能有空格 :是指：ql_backup/config/ldmgr.cnf \的\后面不能有空格，有就会报错：/root/rpmbuild/tmp/rpm-tmp.MVnKem: line 65: /root/rpmbuild/BUILDROOT/etc/mysql_backup/.ldmgr.cnf: No such file or directory
下一行必须紧接
```
