[1] | Install 389 Directory Server |
[root@master ~]#
yum -y install 389-ds openldap-clients
[root@master ~]#
setup-ds-admin.pl # setup ============================================================================== This program will set up the 389 Directory and Administration Servers. It is recommended that you have "root" privilege to set up the software. Tips for using this program: - Press "Enter" to choose the default and go to the next screen - Type "Control-B" then "Enter" to go back to the previous screen - Type "Control-C" to cancel the setup program
Would you like to continue with set up? [yes]:
# Enter ============================================================================== BY SETTING UP AND USING THIS SOFTWARE YOU ARE CONSENTING TO BE BOUND BY AND ARE BECOMING A PARTY TO THE AGREEMENT FOUND IN THE LICENSE.TXT FILE. IF YOU DO NOT AGREE TO ALL OF THE TERMS OF THIS AGREEMENT, PLEASE DO NOT SET UP OR USE THIS SOFTWARE.
Do you agree to the license terms? [no]:
yes # yes ============================================================================== Your system has been scanned for potential problems, missing patches, etc. The following output is a report of the items found that need to be addressed before running this software in a production environment. 389 Directory Server system tuning analysis version 10-AUGUST-2007. NOTICE : System is x86_64-unknown-linux3.1.0-7.fc16.x86_64 (2 processors). ERROR: We support kernel version 2.4.7 and higher. NOTICE : The net.ipv4.tcp_keepalive_time is set to 7200000 milliseconds (120 minutes). This may cause temporary server congestion from lost client connections. WARNING: There are only 1024 file descriptors (soft limit) available, which limit the number of simultaneous connections. ERROR : The above errors MUST be corrected before proceeding.
Would you like to continue? [no]:
yes # yes ============================================================================== Choose a setup type: 1. Express Allows you to quickly set up the servers using the most common options and pre-defined defaults. Useful for quick evaluation of the products. 2. Typical Allows you to specify common defaults and options. 3. Custom Allows you to specify more advanced options. This is recommended for experienced server administrators only. To accept the default shown in brackets, press the Enter key.
Choose a setup type [2]:
# Enter ============================================================================== Enter the fully qualified domain name of the computer on which you're setting up server software. Using the form <hostname>.<domainname> Example: eros.example.com. To accept the default shown in brackets, press the Enter key. Warning: This step may take a few minutes if your DNS servers can not be reached or if DNS is not configured correctly. If you would rather not wait, hit Ctrl-C and run this program again with the following command line option to specify the hostname: General.FullMachineName=your.hostname.domain.name
Computer name [master.srv.world]:
# make sure hostname ( if different, replace it ) ============================================================================== The servers must run as a specific user in a specific group. It is strongly recommended that this user should have no privileges on the computer (i.e. a non-root user). The setup procedure will give this user/group some permissions in specific paths/files to perform server-specific operations. If you have not yet created a user and group for the servers, create this user and group using your native operating system utilities.
System User [nobody]:
# Enter System Group [nobody]: # Enter ============================================================================== Server information is stored in the configuration directory server. This information is used by the console and administration server to configure and manage your servers. If you have already set up a configuration directory server, you should register any servers you set up or create with the configuration server. To do so, the following information about the configuration server is required: the fully qualified host name of the form <hostname>.<domainname>(e.g. hostname.example.com), the port number (default 389), the suffix, the DN and password of a user having permission to write the configuration information, usually the configuration directory administrator, and if you are using security (TLS/SSL). If you are using TLS/SSL, specify the TLS/SSL (LDAPS) port number (default 636) instead of the regular LDAP port number, and provide the CA certificate (in PEM/ASCII format). If you do not yet have a configuration directory server, enter 'No' to be prompted to set up one.
Do you want to register this software with an existing
configuration directory server? [no]: # Enter ============================================================================== Please enter the administrator ID for the configuration directory server. This is the ID typically used to log in to the console. You will also be prompted for the password.
Configuration directory server
administrator ID [admin]: # Enter Password: # set admin password Password (confirm): # confirm ============================================================================== The information stored in the configuration directory server can be separated into different Administration Domains. If you are managing multiple software releases at the same time, or managing information about multiple domains, you may use the Administration Domain to keep them separate. If you are not using administrative domains, press Enter to select the default. Otherwise, enter some descriptive, unique name for the administration domain, such as the name of the organization responsible for managing the domain.
Administration Domain [srv.world]:
# make sure domain name ============================================================================== The standard directory server network port number is 389. However, if you are not logged as the superuser, or port 389 is in use, the default value will be a random unused port number greater than 1024. If you want to use port 389, make sure that you are logged in as the superuser, that port 389 is not in use.
Directory server network port [389]:
# Enter ============================================================================== Each instance of a directory server requires a unique identifier. This identifier is used to name the various instance specific files and directories in the file system, as well as for other uses as a server instance identifier.
Directory server identifier [master]:
# Enter ============================================================================== The suffix is the root of your directory tree. The suffix must be a valid DN. It is recommended that you use the dc=domaincomponent suffix convention. For example, if your domain is example.com, you should use dc=example,dc=com for your suffix. Setup will create this initial suffix for you, but you may have more than one suffix. Use the directory server utilities to create additional suffixes.
Suffix [dc=srv, dc=world]:
# Enter ============================================================================== Certain directory server operations require an administrative user. This user is referred to as the Directory Manager and typically has a bind Distinguished Name (DN) of cn=Directory Manager. You will also be prompted for the password for this user. The password must be at least 8 characters long, and contain no spaces. Press Control-B or type the word "back", then Enter to back up and start over.
Directory Manager DN [cn=Directory Manager]:
# Enter Password: # set Directory Manager's password Password (confirm): # confirm ============================================================================== The Administration Server is separate from any of your web or application servers since it listens to a different port and access to it is restricted. Pick a port number between 1024 and 65535 to run your Administration Server on. You should NOT use a port number which you plan to run a web or application server on, rather, select a number which you will remember and which will not be used for anything else.
Administration port [9830]:
# Enter ============================================================================== The interactive phase is complete. The script will now set up your servers. Enter No or go Back if you want to change something.Are you ready to set up your servers? [yes]: # Enter Creating directory server . . . Warning: Hostname master.srv.world is valid, but none of the IP addresses resolve back to master.srv.world address 10.0.0.100 resolves to host master Your new DS instance 'master' was successfully created.
