How to use Docker to build OpenLDAP+phpLDAPadmin unified user authentication

1. Background

Use LDAP to centrally manage operation and maintenance related usernames and passwords. One account can be used to log in to multiple different systems.
Manual deployment has all kinds of problems. Later, Docker deployment was adopted. After referring to many tutorial documents, the following summary is available for personal testing.

2. Deploy Docker to build LDAP

# Pull the image docker pull osixia/openldap:1.3.0
 
# Create and enter the mapping directory mkdir -p /usr/local/ldap && cd /usr/local/ldap
 
# Start the container docker run \
  -d \
  -p 389:389 \
  -p 636:636 \
  -v /usr/local/ldap:/usr/local/ldap \
  --name ldap \
  osixia/openldap:1.3.0
 
#Default configuration dn dc=example,dc=org
admin admin,dc=example,dc=org
password admin

Enter the container and verify whether it is available

# Enter the container docker exec -it ldap /bin/bash
 
# Execute the query ldapsearch -x -H ldap://localhost:389 -b dc=example,dc=org -D "cn=admin,dc=example,dc=org" -w admin
 
# Or execute the query directly outside the container docker exec -it ldap ldapsearch -x -H ldap://localhost:389 -b dc=example,dc=org -D "cn=admin,dc=example,dc=org" -w admin

Docker builds phpLDAPadmin

# Pull the image docker pull osixia/phpldapadmin
 
# Start the container docker run -dit \
> -p 8081:80 \
> --link ldap \
> --name suiyue_pla \
> --env PHPLDAPADMIN_HTTPS=false \
> --env PHPLDAPADMIN_LDAP_HOSTS=ldap \
> --restart always \
> --detach osixia/phpldapadmin

Finish

Enter http://localhost:8081/ Username: admin,dc=example,dc=org Password: admin
