# Overview

## Operating systems

This role will work on the following operating systems:

 * Red Hat
 * Debian
 * Ubuntu

So, you'll need one of those operating systems.. :-)
Please send Pull Requests or suggestions when you want to use this role for other Operating systems.

# Requirements
## Ansible 2.10 and higher

With the release of Ansible 2.10, modules have been moved into collections.  With the exception of ansible.builtin modules, this means additonal collections must be installed in order to use modules such as seboolean (now ansible.posix.seboolean).  The following collection is now required: `ansible.posix`.  Installing the collection:

```sh
ansible-galaxy collection install ansible.posix
```

If you are willing to create proxy in Zabbix via API as a part of this role execution then you need to install `ansible.netcommon` collection too:

```
ansible-galaxy collection install ansible.netcommon
```

### MySQL

When you are a MySQL user and using Ansible 2.10 or newer, then there is a dependency on the collection named `community.mysql`. This collections are needed as the `mysql_` modules are now part of collections and not standard in Ansible anymmore. Installing the collection:

```sh
ansible-galaxy collection install community.mysql
```

### PostgreSQL

When you are a PostgreSQL user and using Ansible 2.10 or newer, then there is a dependency on the collection named `community.postgresql`. This collections are needed as the `postgresql_` modules are now part of collections and not standard in Ansible anymmore. Installing the collection:

```sh
ansible-galaxy collection install community.postgresql
```

## Zabbix Versions

See the following list of supported Operating systems with the Zabbix releases.

| Zabbix              | 6.4 | 6.2 | 6.0 |

# Role Variables

## Main variables

The following is an overview of all available configuration default for this role.

### Zabbix Proxy

* `zabbix_proxy_version`:  Optional. The latest available major.minor version of Zabbix will be installed on the host(s). If you want to use an older version, please specify this in the major.minor format. Example: `zabbix_proxy_version: 6.0`.
* `zabbix_proxy_version_minor`: When you want to specify a minor version to be installed. RedHat only. Default set to: `*` (latest available)

* `zabbix_proxy_install_database_client`: Default: `True`. False does not install database client.
* `zabbix_proxy_manage_service`: Default: `True`. When you run multiple Zabbix proxies in a High Available cluster setup (e.g. pacemaker), you don't want Ansible to manage the zabbix-proxy service, because Pacemaker is in control of zabbix-proxy service.
* `zabbix_proxy_include_mode`: Default: `0755`. The "mode" for the directory configured with `zabbix_proxy_include`.
* `zabbix_proxy_conf_mode`: Default: `0644`. The "mode" for the Zabbix configuration file.

### Database specific

* `zabbix_proxy_dbhost_run_install`: Default: `True`. When set to `True`, sql files will be executed on the host running the database.
* `zabbix_proxy_database`: Default: `mysql`. The type of database used. Can be: `mysql`, `pgsql` or `sqlite3`
* `zabbix_proxy_dbhost`: Default: localhost. The hostname on which the database is running. Will be ignored when `sqlite3` is used as database.

### SElinux

* `zabbix_proxy_selinux`: Default: `False`. Enables an SELinux policy so that the Proxy will run.

## Proxy

When the target host does not have access to the internet, but you do have a proxy available then the following properties needs to be set to download the packages via the proxy:

* `zabbix_http_proxy`
* `zabbix_https_proxy`

## Database

With Zabbix Proxy you can make use of 2 different databases:

* MySQL
* PostgreSQL
* SQLite3

In the following paragraphs we dive into both setups.

### MySQL

To make the Zabbix Proxy work with a `MySQL` database, there are 2 types on setup:

1. Local setup, `MySQL` running on same host as the Zabbix Proxy;
2. Separate setup, `MySQL` running on a different host than the Zabbix Proxy.

#### Local Setup

We need to have the following dependencies met:

1. Find an (Ansible) role that will install a `MySQL` instance on the host. Example: `geerlingguy.mysql` can be used, but also others can be used. Please make sure that before installing the Zabbix Proxy, you have a fully functional `MySQL` instance running.
2. We need to set some variables, either as input for the playbook or set them into the `group_vars` or `host_vars` (Your preference choice). We need to set the following properties:

```yaml
zabbix_proxy_database: mysql
zabbix_proxy_dbport: 3306
zabbix_proxy_dbpassword: <SOME_SECRET_STRING>
```

Please generate a value for the `zabbix_proxy_dbpassword` property (Maybe use `ansible-vault` for this). The zabbix-proxy role will create an database and username (With the provided value for the password) in `MySQL`.

3. Execute the role by running the Ansible playbook that calls this role. At the end of this run, the Zabbix Proxy with `MySQL` will be running.

#### Separate Setup

We need to have the following dependencies met:

1. We need to either have a `MySQL` instance running somewhere in the environment. If this is the case, we need to have a username/password combination that is allowed to create a database and an user account. If there isn't one, please make sure there is one.
2. We need to set some variables, either as input for the playbook or set them into the `group_vars` or `host_vars` (Your preference choice). We need to set the following properties:

```yaml
zabbix_proxy_database: mysql
zabbix_proxy_dbport: 3306
zabbix_proxy_dbhost: mysql-host
zabbix_proxy_dbhost_run_install: false
zabbix_proxy_dbpassword: <SOME_SECRET_STRING>
zabbix_proxy_privileged_host: '%'
zabbix_proxy_mysql_login_host: mysql-host
zabbix_proxy_mysql_login_user: root
zabbix_proxy_mysql_login_password: changeme
zabbix_proxy_mysql_login_port: 3306
```

Please generate a value for the `zabbix_proxy_dbpassword` property (Maybe use `ansible-vault` for this). The zabbix-proxy role will create an database and username (With the provided value for the password) in `MySQL`.

The `zabbix_proxy_privileged_host` can be set to the hostname/ip of the host running Zabbix Proxy for security related purposes. Also make sure that `zabbix_proxy_mysql_login_password` is set to the correct password for the user provided with `zabbix_proxy_mysql_login_host` to create a database and user in the `MySQL` instance.

3. Execute the role by running the Ansible playbook that calls this role. At the end of this run, the Zabbix Proxy with `MySQL` on a different host will be running.

### PostgreSQL

To make the Zabbix Proxy work with a `PgSQL` database, there are 2 types on setup:

1. Local setup, `PgSQL` running on same host as the Zabbix Proxy;
2. Separate setup, `PgSQL` running on a different host than the Zabbix Proxy.

#### Local Setup

We need to have the following dependencies met:

1. Find an (Ansible) role that will install a `PgSQL` instance on the host. Example: `geerlingguy.postgresql` can be used, but also others can be used. Please make sure that before installing the Zabbix Proxy, you have a fully functional `PgSQL` instance running.
2. We need to set some variables, either as input for the playbook or set them into the `group_vars` or `host_vars` (Your preference choice). We need to set the following properties:

```yaml
zabbix_proxy_database: pgsql
zabbix_proxy_dbport: 5432
zabbix_proxy_dbpassword: <SOME_SECRET_STRING>
```

Please generate a value for the `zabbix_proxy_dbpassword` property (Maybe use `ansible-vault` for this). The zabbix-proxy role will create an database and username (With the provided value for the password) in `PgSQL`.
3. Execute the role by running the Ansible playbook that calls this role. At the end of this run, the Zabbix Proxy with `PgSQL` will be running.

#### Separate Setup

We need to have the following dependencies met:

1. We need to either have a `PgSQL` instance running somewhere in the environment. If this is the case, we need to have a username/password combination that is allowed to create a database and an user account. If there isn't one, please make sure there is one.
2. We need to set some variables, either as input for the playbook or set them into the `group_vars` or `host_vars` (Your preference choice). We need to set the following properties:

```yaml
zabbix_proxy_database: pgsql
zabbix_proxy_dbport: 5432
zabbix_proxy_dbhost: pgsql-host
zabbix_proxy_dbhost_run_install: false
zabbix_proxy_dbpassword: <SOME_SECRET_STRING>
zabbix_proxy_privileged_host: '%'
zabbix_proxy_pgsql_login_host: pgsql-host
zabbix_proxy_pgsql_login_user: postgres
zabbix_proxy_pgsql_login_password: changeme
zabbix_proxy_pgsql_login_port: 5432
```

Please generate a value for the `zabbix_proxy_dbpassword` property (Maybe use `ansible-vault` for this). The zabbix-proxy role will create an database and username (With the provided value for the password) in `PgSQL`.

The `zabbix_proxy_privileged_host` can be set to the hostname/ip of the host running Zabbix Proxy for security related purposes. Also make sure that `zabbix_proxy_mysql_login_password` is set to the correct password for the user provided with `zabbix_proxy_mysql_login_host` to create a database and user in the `PgSQL` instance.

3. Execute the role by running the Ansible playbook that calls this role. At the end of this run, the Zabbix Proxy with `PgSQL` on a different host will be running.zabbix_proxy_

### SQLite3

The SQLite3 can only be used on the same host as on which the Zabbix Proxy is running. If you want to use a seperate host for running the database for the proxy, please consider going for MySQL or PostGreSQL.

The following properties needs to be set when using `SQLite3` as the database:

```yaml
zabbix_proxy_database: sqlite3
zabbix_proxy_dbname: /path/to/sqlite3.db
```

NOTE: When using `zabbix_proxy_dbname: zabbix_proxy` (Which is default with this role), it will automatically be stored on `/var/lib/zabbix/zabbix_proxy.db`

## Zabbix API variables

These variables need to be overridden when you want to make use of the Zabbix API for automatically creating and or updating proxies, i.e. when `zabbix_api_create_proxy` is set to `True`.

* `zabbix_api_server_host`: The IP or hostname/FQDN of Zabbix server. Example: zabbix.example.com
* `zabbix_api_use_ssl`: Is SSL required to connect to the Zabbix API server?  Default: `false`
* `zabbix_api_server_port`: 80 if `zabbix_api_use_ssl` is `false` and 443 if `true` (Default) TCP port to use to connect to Zabbix server. Example: 8080
* `zabbix_api_login_user`: Username of user which has API access.
* `zabbix_api_login_pass`: Password for the user which has API access.
* `zabbix_api_http_user`: The http user to access zabbix url with Basic Auth (if your Zabbix is behind a proxy with HTTP Basic Auth).
* `zabbix_api_http_password`: The http password to access zabbix url with Basic Auth (if your Zabbix is behind a proxy with HTTP Basic Auth).
* `zabbix_api_validate_certs`: yes (Default) if we need to validate tls certificates of the API. Use `no` in case self-signed certificates are used.
* `zabbix_api_timeout`: timeout for API calls (default to 30 seconds)
* `ansible_zabbix_url_path`: URL path if Zabbix WebUI running on non-default (zabbix) path, e.g. if http://<FQDN>/zabbixeu then set to `zabbixeu`
* `zabbix_api_create_proxy`: When you want to enable the Zabbix API to create/delete the proxy. This has to be set to `True` if you want to make use of `zabbix_proxy_state`. Default: `False`
* `zabbix_proxy_name`: name of the Zabbix proxy as it is seen by Zabbix server
* `zabbix_proxy_state`: present (Default) if the proxy needs to be created or absent if you want to delete it. This only works when `zabbix_api_create_proxy` is set to `True`.
* `zabbix_proxy_status`: active (Default) if the proxy needs to be active or passive.
