Sun Java ES 5 - instalace Directory Serveru II

23.4.2007 11:24 | Přečteno: 1561× | Sun Java ES | | poslední úprava: 25.4.2007 14:31

   V minulém dílu jsme nainstalovali DS a ověřili jsme jeho funkčnost. Dnes se podíváme na startovací prostředí, LDAPS a doprovodné utility.

Startovací prostředí

U serverů jako DS, je většinou žádoucí aby se automaticky nastartovali po (re)bootu systému. Tuto funkčnost si zprovozníme.

Pokud vyzkoušíte obligátní /etc/init.d/dsee_directory start zjistíte, že se nic nenastartovalo. Proč? DS je stavěn na běh víc instancí/stromů zároveň. Proto je třeba DS oznámit které z instancí chceme automaticky startovat. Použijeme k tomu program dsadm (popis).

[root@sjes ~]# 
[root@sjes ~]# # Nastavíme instanci DS /var/opt/sun/ds-example.com na autostart
[root@sjes ~]# /opt/sun/ds6/bin/dsadm autostart /var/opt/sun/ds-example.com
The instance /var/opt/sun/ds-example.com will be started at boot time now.
[root@sjes ~]#
[root@sjes ~]# # vyzkoušíme jestli startovací script opravdu funguje
[root@sjes ~]# /etc/init.d/dsee_directory start
/etc/init.d/dsee_directory: Starting Directory Server Instance: /var/opt/sun/ds-example.com
Server started: pid=2635
[root@sjes ~]# 
[root@sjes ~]# # kontrola spuštění DS
[root@sjes ~]# ps -ef | grep ns-slapd
root      2635     1  1 16:08 ?        00:00:00 ns-slapd -D /var/opt/sun/ds-example.com -i /var/opt/sun/ds-example.com/logs/pid
root      2690  3265  0 16:08 pts/0    00:00:00 grep ns-slapd
[root@sjes ~]# 

Povedlo se.
Teď už zbývá jen přidat startovací script démona do správných init level

[root@sjes ~]# 
[root@sjes ~]# chkconfig dsee_directory on 
[root@sjes ~]# chkconfig --list dsee_directory  
dsee_directory  0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root@sjes ~]# 

Java Web Console

JES 5 (a poslední dobou čím dál víc SUN produktů) má propracovanou WEB consoli. Pokud ji budete chtít používat doporučuji tento popis principů s ohledem na DS. Já se omezím na její zprovoznění.

---

Dejte pozor na nastavení iptables (a FW obecně) !!! Pokud je máte nahozené a nepovolili jste port 6789 tak toho moc neuvidíte ...

---

Zatím je přístupná pouze DS Control Center v levé dolní části. Přihlašte se do ní (admin:adminadmin z minulého dílu) a v "Directory Servers" uvidíte váš DS. V záložce Settings/Directory Service Managers klikněte na admin a změňte mu heslo na "dscc6pwd"

ahoj instaloval/konfiguroval jsi JES s externim DS serverem. Dekuji za napovedu D
