Netscaler重置密碼的方法

  有時(shí)候我們會(huì)碰到忘記Netscaler的密碼，或接手別人的設(shè)備而不知道密碼的情況。在這種情況下能看到但進(jìn)不去，那感覺(jué)真是酸爽！如何初始化Netscaler的密碼，及時(shí)啟用手上的設(shè)備就很重要了。

用console線連接到Netscaler，按啟動(dòng)按鈕后會(huì)看到以下內(nèi)容，按照如下提示操作即可

1.       Attach a console cable to the Serial Console (9600 baud, 8 bits, 1 stop bit, No parity) of the NetScaler appliance.

2.       Restart the NetScaler appliance.

3.       Press any of the following keys, as prompted:

Press Spacebar when the following message is displayed:

Hit [Enter] to boot immediately, or any other key for command prompt Booting [kernel] in 10 seconds

Press Ctrl and C keys simultaneously when the following message is displayed:

Press [Ctrl-C] for command prompt, or any other key to boot immediately.

Booting [kernel] in 2 seconds...

4.       To start the appliance kernel on a single user mode, enter the following command:

boot –s

Note: If boot -s does not work, then try reboot -- -s and appliance will reboot in single user mode.

5.       Press Enter when the following message is displayed:

Enter full pathname of shell or RETURN for /bin/sh:

Note: Notice that the prompt of the appliance changes to \u@\h\$.

6.       Run the following command to check the disk consistency:

\u@\h\$ /sbin/fsck /dev/ad0s1a（此命令一定要先執(zhí)行，否則不能掛載/flash）

Note: Refer to the Knowledge Center article CTX121853 – Device Names Assigned to Hard Disk in Various Models of the Citrix NetScaler Appliance to verify the device name assigned to the hard disk of the appliance model and replace ad0s1a in the preceding command with the appropriate device name.

7.       Run the following command to display the mounted partitions:

df

8.       Run the following command to mount the flash drive:

\u@\h\$ /sbin/mount /dev/ad0s1a /flash( 一定要把flash掛上，否則看不到ns.conf）

If the preceding command fails to mount the flash drive, then run the following command to create the flash directory and then run the preceding command again to mount the drive:

\u@\h\$ mkdir /flash（如果有/flash可以不執(zhí)行這步）

9.       Run the following command to change to the nsconfig directory:

\u@\h\$ cd /flash/nsconfig

10.     Run the following set of commands to rewrite the ns.conf file and remove the set of system commands defaulting to the nsroot user:

a. Run the following command to create a new configuration file that does not have commands defaulting to the nsroot user:

\u@\h\$ grep –v “set system user nsroot” ns.conf > new.conf（提取除nsroot用戶以外的其他配置到新文件）

b. Run a command similar to the following command to make a backup of the existing configuration file:

\u@\h\$ mv ns.conf old.ns.conf（備份原來(lái)的配置）

c. Run the following command to rename the new.conf file to ns.conf:

\u@\h\$ mv new.conf ns.conf（用沒(méi)有nsroot的配置啟動(dòng)）

11.     Run the following command to restart the appliance:

reboot

12.     Log in to the appliance by using the default nsroot user credentials.

此時(shí)nsroot的密碼為初始化的密碼，直接輸入nsroot登陸即可

13.     Run the following command to reset the nsroot user password of your choice:

> set system user nsroot <New_Password>重新輸入密碼
