1.3. PostgreSQL 官方 YUM 源安裝

CentOS 6.4 環境 YUM 地址 http://yum.postgresql.org/

1.3.1. 9.2

# yum install http://yum.postgresql.org/9.2/redhat/rhel-6-x86_64/pgdg-centos92-9.2-6.noarch.rpm
# yum list postgres*

# yum install postgresql92-server postgresql92

chkconfig postgresql-9.2 on
service postgresql-9.2 initdb
service postgresql-9.2 start
			

配置檔案的位置

# ls /var/lib/pgsql/9.2/data/*.conf
/var/lib/pgsql/9.2/data/pg_hba.conf  /var/lib/pgsql/9.2/data/pg_ident.conf  /var/lib/pgsql/9.2/data/postgresql.conf
			

1.3.2. 9.3

# yum install http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/pgdg-centos93-9.3-1.noarch.rpm
# yum install postgresql93-server postgresql93
			
# chkconfig postgresql-9.3 on
# service postgresql-9.3 initdb
# service postgresql-9.3 start			
			

9.2 升級到 9.3

備份資料庫

# su - postgres
$ pg_dump -f wechat.sql wechat
			

升級資料庫

關閉9.2,啟動9。3

# chkconfig postgresql-9.2 off
# service postgresql-9.2 stop

# service postgresql-9.3 start
			

回覆資料庫

# su - postgres
$ createuser -r -s -P dba
$ createuser -P wechat
$ createdb -E UTF8 -O wechat wechat
$ cat wechat.sql | psql wechat
			

合併配置檔案

$ cp 9.3/data/postgresql.conf{,.original}
$ cp 9.3/data/pg_hba.conf{,.original}
$ vimdiff 9.2/data/postgresql.conf 9.3/data/postgresql.conf
$ vimdiff 9.2/data/pg_hba.conf 9.3/data/pg_hba.conf
			

注意 vimdiff 命令是檔案對比于合併工具,建議你選擇你比較熟悉的工具。

# service postgresql-9.3 restart

配置訪問控制列表 /var/lib/pgsql/10/data/pg_hba.conf 加入

# vim /var/lib/pgsql/10/data/pg_hba.conf
host    *               dba         0.0.0.0/0       md5     
host    test            test        0.0.0.0/0       md5
			

確認防火牆已經放行5432連接埠

# cat /etc/sysconfig/iptables | grep 5432 -A INPUT -s 172.16.0.0/24 -p tcp -m state --state NEW -m tcp --dport 5432 -j ACCEPT

例 1.1. Example for /var/lib/pgsql/10/data/pg_hba.conf

# cat /var/lib/pgsql/10/data/pg_hba.conf
# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the "Client Authentication" section in the PostgreSQL
# documentation for a complete description of this file.  A short
# synopsis follows.
#
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which PostgreSQL user names they can use, which
# databases they can access.  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]
#
# (The uppercase items must be replaced by actual values.)
#
# The first field is the connection type: "local" is a Unix-domain
# socket, "host" is either a plain or SSL-encrypted TCP/IP socket,
# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
# plain TCP/IP socket.
#
# 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.
