# names and passwords for administrative users
|
|
mongodb_user_admin_name: siteUserAdmin
|
|
mongodb_user_admin_password: passw0rd
|
|
|
|
mongodb_root_admin_name: siteRootAdmin
|
|
mongodb_root_admin_password: passw0rd
|
|
```
|
|
|
|
#### Usage
|
|
|
|
Add `greendayonfire.mongodb` to your roles and set vars in your playbook file.
|
|
|
|
Example vars for authorization:
|
|
```yaml
|
|
mongodb_security_authorization: "enabled"
|
|
mongodb_users:
|
|
- {
|
|
name: testUser,
|
|
password: passw0rd,
|
|
roles: readWrite,
|
|
database: app_development
|
|
}
|
|
```
|
|
Required vars to change on production:
|
|
```yaml
|
|
mongodb_user_admin_password
|
|
mongodb_root_admin_password
|
|
mongodb_root_backup_name
|
|
|
|
# if you use replication and authorization
|
|
mongodb_security_keyfile
|
|
```
|
|
Example vars for replication:
|
|
```yaml
|
|
# It's a 'master' node
|
|
mongodb_login_host: 192.168.56.2
|
|
|
|
# mongodb_replication_params should be configured on each replica set node
|
|
mongodb_replication_params:
|
|
- { host_name: 192.168.56.2, host_port: "{{ mongodb_net_port }}", host_type: replica }
|
|
# host_type can be replica(default) and arbiter
|
|
```
|
|
And inventory file for replica set:
|
|
```ini
|
|
[mongo_master]
|
|
192.158.56.2 mongodb_master=True # it is't a really master of MongoDB replica set,
|
|
# use this variable for replica set init only
|
|
# or when master is moved from initial master node
|
|
|
|
[mongo_replicas]
|
|
192.168.56.3
|
|
192.168.56.4
|
|
|
|
[mongo:children]
|
|
mongo_master
|
|
mongo_replicas
|
|
```
