Creating service files to auto start and stop SDS on RHEL

In my previous – quite long – post, I showed you all how to install from scratch IBM SDS LDAP server with some additional fancy tools. Today I’ll show you how to create two service files for SDS (one for the Directory Administrator instance and one for the LDAP server instance) to make the system able to automatically start or stop those processes during system boot or halt. Let’s get started.

Creating service file for LDAP server instance

First things first, we need to know where my instances are and what the name of the instance. To do so, issue the following command as root:

/opt/ibm/ldap/V6.4/bin/idsilist -a

which list all the configured instances on the system, in my case my instance name is: idsldap

Now we can create a systemd service file with the content below:

cat >> /etc/systemd/system/ibmslapd_idsldap.service << EOF
# Start of service file

[Unit]
Description=IBM Security Directory Server idsldap
After=network.target

[Service]
Type=forking
ExecStart=/opt/IBM/ldap/V6.4/sbin/ibmslapd -I idsldap -n
ExecStop=/opt/IBM/ldap/V6.4/sbin/ibmslapd -I idsldap -k

[Install]
WantedBy=multi-user.target

# End of service file

EOF

Final step on RHEL is to enable and then start the newly created service with the following command:

systemctl enable ibmslapd_idsldap.service
systemctl start ibmslapd_idsldap.service

If you did everything fine, issuing the following command once the start command finished will report that idsldap IBM SDS instance is up and running:

systemctl status ibmslapd_idsldap.service

Creating service file for Directory Administration instance

To create the other service file for the Directory Administrator instance, we create a similar service file:

cat >> /etc/systemd/system/ibmdiradm_idsldap.service << EOF

# Start of service file

[Unit]
Description=IBM Security Directory Admin Server idsldap
After=network.target

[Service]
Type=forking
ExecStart=/opt/IBM/ldap/V6.4/sbin/ibmdiradm -I idsldap
ExecStop=/opt/IBM/ldap/V6.4/sbin/ibmdiradm -I idsldap -k

[Install]
WantedBy=multi-user.target

# End of service file
EOF

Final step on RHEL is to enable and then start the newly created service with the following command:

systemctl enable ibmdiradm_idsldap.service
systemctl start ibmdiradm_idsldap.service

If you did everything fine, issuing the following command once the start command finished will report that idsldap IBM Directory Administration instance is up and running:

systemctl status ibmdiradm_idsldap.service
