Dcli工具可以从一台服务器上发起命令控制多台服务器， 但是dcli不支持远程应用使用交互式的方式。
以下为Dcli的语法：
| –version | Shows the version number of the program and then exits. |
| -c cells | Specifies a comma-delimited list of target cells to which commands are sent. |
| -d destfile | Specifies the target destination directory or file on remote cells to be used when copying files or directories using the -f option. |
| -f file | Specifies the files to be copied to the cells. These files are not run. These files can be script files to be run later. The files are copied to the default home directory of the user on the target cell. |
| -g groupFile | Specifies a file containing a list of target cells to which commands are sent. The cells can be identified by cell names or IP addresses. |
| -h, –help | Displays help text and then exits. |
| -k | Sets up SSH user-equivalence for the current user to the cells specified with the -c or -g option by appending public key files to the authorized_keys file on cells. |
| -l | userId Identifies the user to log in as on remote cells. The default is the celladmin user. |
| -n | Abbreviates nonerror output. Cells that return normal output |
| (return code of 0) only have the cell name listed. | |
| The -n and -r options cannot be used together. | |
| -r | regexp Abbreviates the output lines that match a regular expression. All output lines with that pattern are deleted from output, and the cells names from those output lines are listed on one line. The -r and -n options cannot be used together. |
| -s | sshOptions Passes a string of options to SSH. |
| –scp= scpOptions | Passes a string of options to scp if different from sshoptions. |
| -t | Displays the target cells that are named with the -c option or in the groupfile identified by the -g option. |
| -v | Prints the verbose version of messages to stdout. |
| –vmstat=VMSTATOPS | Displays view process, virtual memory, disk, trap, and CPU activity information, depending on the switches. |
| -x | execFile Specifies the command file to be copied and run on the cells. The specified file contains a list of commands. A file with the .scl extension is run by the CellCLI utility. A file with a different extension is run by the operating system shell on the cell. The file is copied to the default home directory of the user on the target cell. |
使用示例：
注意dbs_group 、all_group 、all_ib_group、cell_group、cell_ib_group等组文件一般仅在第一台computenode上有
