Install PostgreSQL 14.04 on Ubuntu 9.2

I. Environment

Vmvm

NAME = "Ubuntu"
VERSION = "12.04.4 LTS, Precise Pangolin"

Ii. Process

1. Install make. Do not install make now.

# Apt-get install make

# Make -- version
GNU Make 3.81

2. Get source code

However, there are ready-made binary installation packages and the installation methods are provided based on different systems. Http://www.postgresql.org/download/

The source code is obtained from git on File Browser or directly from the version control repository. The Operation Document installed with the source code is here. Http://www.postgresql.org/docs/current/static/installation.html

Open the ubuntu option page and take a look at what I said, http://www.postgresql.org/download/linux/ubuntu /. Ubuntu already contains PostgreSQL by default. Now you can use apt-get to install it. If the pgsql version on Ubuntu is not what you want, you can use PostgreSQL Apt repository to integrate the patch, and then the following is the basic operation steps, more Apt-related information see wiki, https://wiki.postgresql.org/wiki/Apt.

In wiki, PGDG is a group that supports APT repository maintenance. They are committed to building PostgreSQL server packages as well as extensions and modules packages on several Debian/Ubuntu releases for all PostgreSQL versions supported. PostgreSQL and its related packages are released for different releases. The following is a quick start installation step. Follow the wiki.

3. Install

Add source and update source

# Sudo sh-c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ $ (lsb_release-cs)-pgdg main">/etc/apt/sources. list. d/pgdg. list'
# Apt-get update

PS: this variable can get the version code.
# Echo $ (lsb_release-cs)
Precise
# Cat/etc/apt/sources. list. d/pgdg. list
Deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main

After the source is updated, you can search for postgresql of each version. After reading about it, there are also 8.2 versions. The latest version is 9.5.

# Apt-cache search postgresql-| grep 'object-relational '| less
Postgresql-9.1-object-relational SQL database, version 9.1 server
Postgresql-8.4-object-relational SQL database, version 8.4 server
Postgresql-8.2-object-relational SQL database, version 8.2 server
Postgresql-8.3-object-relational SQL database, version 8.3 server
Postgresql-9.0-object-relational SQL database, version 9.0 server
Postgresql-9.2-object-relational SQL database, version 9.2 server
Postgresql-9.3-object-relational SQL database, version 9.3 server
Postgresql-9.4-object-relational SQL database, version 9.4 server
Postgresql-9.5-object-relational SQL database, version 9.5 server

4. configure remote access

After PostgreSQL is installed, the postgres user password on Ubuntu is unknown and the postgres password on the database is not set.

If you use root or allow sudo, you can directly Force Logon with the postgres user without knowing the postgres password.

Root # su ipvs
Postgres $ psql
Psql (9.2.13)
Enter "help" to obtain help information.

Postgres = #

(Non-root users are allowed to use sudo. Password-free is set here) $ sudo-u postgres psql
Psql (9.2.13)
Enter "help" to obtain help information.

Postgres = #

After logon, set a password for postgres of SQL.

Postgres # \ password postgres

Log out and find a directory. You need to modify two files, postgresql. conf and pg_assist.conf.

# Find/-name postgresql. conf
/Etc/postgresql/9.2/main/postgresql. conf
# Cd/etc/postgresql/9.2/main/
# L
Environment pg_ctl.conf pg_mirror.conf pg_ident.conf postgresql. conf start. conf

Postgresql. conf listens to all IP addresses, default ports, and enables log collection. A new log is generated every day, and many parameters that you don't know can be called.

Listen_addresses = '*' # what IP address (es) to listen on;
# Comma-separated list of addresses;
# Defaults to 'localhost'; use '*' for all
# (Change requires restart)
Port = 5432 # (change requires restart)
Logging_collector = on # Enable capturing of stderr and csvlog
# Into log files. Required to be on
# Csvlogs.
# (Change requires restart)
Log_directory = 'pg _ log' # directory where log files are written,
# Can be absolute or relative to PGDATA
Log_filename = 'postgresql-% Y-% m-% d _ % H % M % S. log' # log file name pattern,
# Can include strftime () escapes
Log_truncate_on_rotation = off # If on, an existing log file with
# Same name as the new log file will be
# Truncated rather than appended.
# But such truncation only occurs on
# Time-driven rotation, not on restarts
# Or size-driven rotation. Default is
# Off, meaning append to existing files
# In all cases.
Log_rotation_age = 1d # Automatic rotation of logfiles will
# Happen after that time. 0 disables.
Log_rotation_size = 0 # Automatic rotation of logfiles will
# Happen after that much log output.
#0 disables.

Add your own address to pg_mirror.conf, all of which are 0.0.0.0/0.

# IPv4 local connections:
Host all 127.0.0.1/32 md5
Host all 192.168.152.1/24 md5

Restart the postgresql service, and then set the address, port, user name, and password for pgAdminIII to connect.
