3. 测试

                      开启一个screen会话 # screen -L
                                                   [screen is terminating]

                      执行命令  # myloader  -u root -a -S /data/3306/mysql.sock -t 8 -d /data/backup/ -o

                      放入后台知行：control+a+d

                      回到screen： # screen -r
