Records take one of these forms: +# +# local DATABASE USER METHOD [OPTIONS] +# host DATABASE USER ADDRESS METHOD [OPTIONS] +# hostssl DATABASE USER ADDRESS METHOD [OPTIONS] +# hostnossl DATABASE USER ADDRESS METHOD [OPTIONS] +# hostgssenc DATABASE USER ADDRESS METHOD [OPTIONS] +# hostnogssenc DATABASE USER ADDRESS METHOD [OPTIONS] +# +# (The uppercase items must be replaced by actual values.) +# +# The first field is the connection type: +# - "local" is a Unix-domain socket +# - "host" is a TCP/IP socket (encrypted or not) +# - "hostssl" is a TCP/IP socket that is SSL-encrypted +# - "hostnossl" is a TCP/IP socket that is not SSL-encrypted +# - "hostgssenc" is a TCP/IP socket that is GSSAPI-encrypted +# - "hostnogssenc" is a TCP/IP socket that is not GSSAPI-encrypted +# +# DATABASE can be "all", "sameuser", "samerole", "replication", a +# database name, or a comma-separated list thereof. The "all" +# keyword does not match "replication". Access to replication +# must be enabled in a separate record (see example below). +# +# USER can be "all", a user name, a group name prefixed with "+", or a +# comma-separated list thereof. In both the DATABASE and USER fields +# you can also write a file name prefixed with "@" to include names +# from a separate file. +# +# ADDRESS specifies the set of hosts the record matches. It can be a +# host name, or it is made up of an IP address and a CIDR mask that is +# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that +# specifies the number of significant bits in the mask. A host name +# that starts with a dot (.) matches a suffix of the actual host name. +# Alternatively, you can write an IP address and netmask in separate +# columns to specify the set of hosts. Instead of a CIDR-address, you +# can write "samehost" to match any of the server's own IP addresses, +# or "samenet" to match any address in any subnet that the server is +# directly connected to. +# +# METHOD can be "trust", "reject", "md5", "password", "scram-sha-256", +# "gss", "sspi", "ident", "peer", "pam", "ldap", "radius" or "cert". +# Note that "password" sends passwords in clear text; "md5" or +# "scram-sha-256" are preferred since they send encrypted passwords. +# +# OPTIONS are a set of options for the authentication in the format +# NAME=VALUE. The available options depend on the different +# authentication methods -- refer to the "Client Authentication" +# section in the documentation for a list of which options are +# available for which authentication methods. +# +# Database and user names containing spaces, commas, quotes and other +# special characters must be quoted. Quoting one of the keywords +# "all", "sameuser", "samerole" or "replication" makes the name lose +# its special character, and just match a database or username with +# that name. +# +# This file is read on server startup and when the server receives a +# SIGHUP signal. If you edit the file on a running system, you have to +# SIGHUP the server for the changes to take effect, run "pg_ctl reload", +# or execute "SELECT pg_reload_conf()". +# +# Put your actual configuration here +# ---------------------------------- +# +# If you want to allow non-local connections, you need to add more +# "host" records. In that case you will also need to make PostgreSQL +# listen on a non-local interface via the listen_addresses +# configuration parameter, or via the -i or -h command line switches. + + + +# TYPE DATABASE USER ADDRESS METHOD + +local all all trust +# "local" is for Unix domain socket connections only +local all all peer +# IPv4 local connections: +host all all 127.0.0.1/32 scram-sha-256 +# IPv6 local connections: +host all all ::1/128 scram-sha-256 +# Allow replication connections from localhost, by a user with the +# replication privilege. +local replication all peer +host replication all 127.0.0.1/32 scram-sha-256 +host replication all ::1/128 scram-sha-256 +{% if postgresql_ssl|bool %} +hostssl all all 0.0.0.0/0 scram-sha-256 +{% endif %} diff --git a/templates/15-postgresql.conf.j2 b/templates/15-postgresql.conf.j2 new file mode 100644 index 0000000..2a3cff7 --- /dev/null +++ b/templates/15-postgresql.conf.j2 @@ -0,0 +1,7 @@ +{% for key, value in postgresql_combined_parameters.items() %} +{{ key }} = '{{ value }}' +{% endfor %} + +{% if postgresql_ssl | bool %} +include = 'postgresql.ssl.conf' +{% endif %} diff --git a/templates/15-postgresql.ssl.conf.j2 b/templates/15-postgresql.ssl.conf.j2 new file mode 100644 index 0000000..bc20078 --- /dev/null +++ b/templates/15-postgresql.ssl.conf.j2 @@ -0,0 +1,3 @@ +ssl = on +ssl_cert_file = '{{ postgresql_ssl_path }}/{{ postgresql_self_signed_cert_name }}.crt' +ssl_key_file = '{{ postgresql_ssl_path }}/{{ postgresql_self_signed_cert_name }}.key' diff --git a/vars/Debian.yaml b/vars/Debian.yaml new file mode 100644 index 0000000..a64927a --- /dev/null +++ b/vars/Debian.yaml @@ -0,0 +1,10 @@ +postgresql_apt_key: + - name: org.postgresql.gpg + url: "https://www.postgresql.org/media/keys/ACCC4CF8.asc" + keyring: /etc/apt/trusted.gpg.d/org.postgresql.gpg +postgresql_apt_repository: + - repo: deb http://apt.postgresql.org/pub/repos/apt {{ ansible_distribution_release }}-pgdg main + filename: postgresql + +postgresql_package: "{{ postgresql_package_name }}-{{ postgresql_major_version }}={{ postgresql_version }}" +postgresql_home_dir: "/var/lib/postgresql" diff --git a/vars/RedHat.yaml b/vars/RedHat.yaml new file mode 100644 index 0000000..464ffbf --- /dev/null +++ b/vars/RedHat.yaml @@ -0,0 +1,4 @@ +postgresql_repo_package: "https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm" + +postgresql_package: "{{ postgresql_package_name }}{{ postgresql_major_version }}-server-{{ postgresql_version }}" +postgresql_home_dir: "/var/lib/pgsql" diff --git a/vars/main.yaml b/vars/main.yaml new file mode 100644 index 0000000..fefb5e4 --- /dev/null +++ b/vars/main.yaml @@ -0,0 +1,3 @@ +postgresql_package_name: "postgresql" +postgresql_major_version: "{{ postgresql_version | split('.') | first }}" +postgresql_minor_version: "{{ postgresql_version | split('.') | last }}"
