System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones

Logging In to an lx Branded Zone

Use the zlogin command to log in from the global zone to any zone that is running or in the ready state. See the zlogin(1) man page for more information.

You can log in to a zone in various ways, as described in the following procedures. You can also log in remotely, as described in Remote Login.

ProcedureHow to Log In to the lx Branded Zone Console

You must be the global administrator in the global zone to perform this procedure.

  1. Become superuser, or assume the Primary Administrator role.

    To create the role and assign the role to a user, see Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.

  2. Use the zlogin command with the -C option and the name of the zone, for example, lx-zone.


    global# zlogin -C lx-zone
    [Connected to zone 'lx-zone' console]

    Note –

    If you start the zlogin session immediately after issuing the zoneadm boot command, boot messages from the zone will display:


    INIT: version 2.85 booting
    	                Welcome to CentOS
    	                Press 'I' to enter interactive startup.
    	Configuring kernel parameters:  [  OK  ]
    	Setting hostname lx-zone:  [  OK  ]
    	[...]
    	CentOS release 3.6 (Final)
    	Kernel 2.4.21 on an i686

  3. When the zone console displays, log in as root, press Return, and type the root password when prompted.


    lx-zone console login: root
    Password:

    Note –

    Recall that the root (superuser) password is root when the zone is installed from the Sun tarball. The root (superuser) password is unset (blank) when the zone is installed from ISO images or a CD.


ProcedureHow to Use Interactive Mode to Access a Branded Zone

In interactive mode, a new pseudo-terminal is allocated for use inside the zone.

You must be the global administrator in the global zone to perform this procedure.

  1. Become superuser, or assume the Primary Administrator role.

    To create the role and assign the role to a user, see Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.

  2. From the global zone, log in to the zone, for example, lx-zone.


    global# zlogin lx-zone
    

    Information similar to the following will display:


    [Connected to zone 'lx-zone' pts/2]
    Last login: Wed Jul  3 16:25:00 on console
    Sun Microsystems Inc. SunOS 5.10 Generic July 2006
  3. Type exit to close the connection.

    You will see a message similar to the following:


    [Connection to zone 'lx-zone' pts/2 closed]

ProcedureHow to Verify the Running Environment

You must be the global administrator in the global zone to perform this procedure.

  1. Become superuser, or assume the Primary Administrator role.

    To create the role and assign the role to a user, see Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.

  2. Log in to the zone, for example, lx-zone.


    global# zlogin lx-zone
    
  3. Verify that you are running in a Linux environment under the Solaris Operating System.


    [root@lx-zone root]# uname -a
    

    You will see a display similar to the following:


    Linux lx-zone 2.4.21 BrandZ fake linux i686 i686 i386 GNU/Linux 

ProcedureHow to Use Non-Interactive Mode to Access an lx Branded Zone

Non-interactive mode is enabled when the user supplies a command to be run inside the zone. Non-interactive mode does not allocate a new pseudo-terminal.

Note that the command or any files that the command acts upon cannot reside on NFS.

You must be the global administrator in the global zone to perform this procedure.

  1. Become superuser, or assume the Primary Administrator role.

    To create the role and assign the role to a user, see Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.

  2. From the global zone, log in to the lx-zone zone and supply a command name.

    Replace command with the name of the command to be run inside the zone.


    global# zlogin lx-zone command
    

Example 36–1 Using the Command uptime in the Zone lx_master


global#  zlogin lx_master uptime
	21:16:01  up  2:39,  0 users,  load average: 0.19, 0.13, 0.11
	fireball#

ProcedureHow to Exit the lx Branded Zone

  1. To disconnect from a non-global zone, use one of the following methods.

    • To exit the zone non-virtual console:


      zonename# exit
      
    • To disconnect from a zone virtual console, use the tilde (~) character and a period:


      zonename# ~.
      

      Your screen will look similar to this:


      [Connection to zone 'lx-zone' pts/6 closed]

For more information about zlogin command options, see the zlogin(1) man page.

ProcedureHow to Use Failsafe Mode to Enter an lx Branded Zone

When a connection to the zone is denied, the zlogin command can be used with the -S option to enter a minimal environment in the zone.

You must be the global administrator in the global zone to perform this procedure.

  1. Become superuser, or assume the Primary Administrator role.

    To create the role and assign the role to a user, see Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.

  2. From the global zone, use the zlogin command with the -S option to access the zone, for example, lx-zone.


    global# zlogin -S lx-zone
    

ProcedureHow to Use zlogin to Shut Down an lx Branded Zone


Note –

Running init 0 in the global zone to cleanly shut down a Solaris system also runs init 0 in each of the non-global zones on the system. Note that init 0 does not warn local and remote users to log off before the system is taken down.


Use this procedure to cleanly shut down a zone. To halt a zone without running shutdown scripts, see How to Halt a Zone.

You must be the global administrator in the global zone to perform this procedure.

  1. Become superuser, or assume the Primary Administrator role.

    To create the role and assign the role to a user, see Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.

  2. Log in to the zone to be shut down, for example, lx-zone, and specify shutdown as the name of the utility and init 0 as the state.


    global# zlogin lx-zone shutdown -y -g0 -i0
    

    Your site might have its own shutdown script, tailored for your specific environment.

Using shutdown in Non-Interactive Mode

You cannot use the shutdown command in non-interactive mode to place the zone in single—user state at this time. See 6214427 for more information.

You can use an interactive login as described in How to Use Interactive Mode to Access a Branded Zone.
