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

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. # TYPE DATABASE USER ADDRESS METHOD host * dba 0.0.0.0/0 md5 host test test 0.0.0.0/0 md5 # "local" is for Unix domain socket connections only local all all peer # IPv4 local connections: host all all 127.0.0.1/32 ident # IPv6 local connections: host all all ::1/128 ident # Allow replication connections from localhost, by a user with the # replication privilege. local replication all peer host replication all 127.0.0.1/32 ident host replication all ::1/128 ident
