PostgreSQL在Linux上的RPM和源码安装

第一章 引言

---

此文档主要描述Postgre数据库，基于Red Hat Enterprise Linux Server release 6.5 的操作系统上安装Postgre数据库的文档衍生而来。此文档包括Postgre数据库的多种安装方式。

1.1 背景

本文档介绍Postgre 数据库基于linux 6.5平台的三种安装方式。
 
第二章 部署前规划

---

在部署系统之前，需要对安装存储位置这两方面进行规划。下面分别描述了存储进行规划时，需要注意的地方。

2.1 环境规划

本次环境规划包括postgres用户的家目录，软件安装目录，及数据库目录三大部分。

目录名称	存放位置
Postgres用户家目录	/home/postgres
软件存放目录	/opt/soft
安装目录	/usr/local/
数据目录	/monchickey/pg_data

2.2 软件功能

PostgreSQL is an object-relational database management system (ORDBMS) based on POSTGRES.

PostgreSQL is an open-source descendant of this original Berkeley code. It supports a large part of the SQL standard and offers many modern features:
complex queries
foreign keys
triggers
updatable views
transactional integrity
multiversion concurrency control    

Also, PostgreSQL can be extended by the user in many ways, for example by adding new data types
functions
operators
aggregate functions
index methods
procedural languages

2.3 文档及下载介绍

3.1 解压安装

在操作系统安装完成后，上传安转包后按照目录规划安装postgre数据库。

1）安装部署参考文档

下载页：https://www.enterprisedb.com/download-postgresql-binaries
软件包：postgresql-10.7-2-linux-x64-binaries.tar.gz

2）创建postgre安装用户

useradd postgrespasswd postgres

3）创建postgre安装目录及数据目录

mkdir -p /monchickey/pgsql_datachown -R postgres:postgres /monchickey/pgsql_dataChmod -R 775 /monchickey/pgsql_data

4）解压安装

tar -zxvf postgresql-10.7-2-linux-x64-binaries.tar.gz -C /monchickey [root@rhel6 monchickey]# lltotal 12drwxrwxrwx 9 root root 4096 Apr 10 03:24 pgsqldrwx------ 19 postgres postgres 4096 Apr 15 11:33 pgsql_data

5）初始化数据库

cd /monchickey/pgsql/bin/monchickey/pgsql/bin/initdb -D /monchickey/pgsql_data/eg:[postgres@rhel6 bin]$ ./initdb -D /monchickey/pgsql_data/The files belonging to this database system will be owned by user "postgres".This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8".The default database encoding has accordingly been set to "UTF8".The default text search configuration will be set to "english".
Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connectionsYou can change this by editing pg_hba.conf or using the option -A, or--auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
./pg_ctl -D /monchickey/pgsql_data/ -l logfile start

6）启动数据库

./pg_ctl -D /monchickey/pgsql_data/ -l logfile starteg:[postgres@rhel6 bin]$ ./pg_ctl -D /monchickey/pgsql_data/ -l logfile startwaiting for server to start..../bin/sh: logfile: Permission denied stopped waitingpg_ctl: could not start serverExamine the log output.
解决方法：[root@rhel6 monchickey]# chmod -R 777 pgsql[root@rhel6 monchickey]# lltotal 8drwxrwxrwx 9 root root 4096 Apr 10 03:24 pgsql
[postgres@rhel6 bin]$ ./pg_ctl -D /monchickey/pgsql_data/ -l logfile startwaiting for server to start.... doneserver started

7）停止数据库

./pg_ctl -D /monchickey/pgsql_data/ stop

3.2 使用rpm包安装

使用rpm包安装postgre数据库。需要使用4个rpm包。如果认为系统自带的postgre数据库安装包版本过低，从https://yum.postgresql.org网站上下载。本次安装使用rhel 6.5自带的安装包。

1）安装包信息及顺序

rpm -ivh postgresql92-libs-9.2.4-1PGDG.rhel6.i686.rpm rpm -ivh postgresql92-9.2.4-1PGDG.rhel6.i686.rpmrpm -ivh postgresql92-server-9.2.4-1PGDG.rhel6.i686.rpm rpm -ivh postgresql92-contrib-9.2.4-1PGDG.rhel6.i686.rpm

2）或者使用yum源进行安装

yum install -y postgresql-libsyum install -y postgresqlYum install -y postgresql-serverYum install -y postgresql-contrib

3）初始化数据库

[root@rhel6 Packages]# service postgresql initdbInitializing database: [ OK ]

4）启动数据库服务

[root@rhel6 Packages]# service postgresql startStarting postgresql service: [ OK ]

5）查看默认的psql

[postgres@rhel6 ~]$ psqlpsql (8.4.18)Type "help" for help.

6）停止数据库服务

[postgres@rhel6 ~]$ exitlogout[root@rhel6 Packages]# service postgresql stopStopping postgresql service: [ OK ]

7）卸载数据库

rpm -e postgresql-serverrpm -e postgresql-contribrpm -e postgresqlrpm -e postgresql-libs

3.3 编译安装

使用二进制文件进行编译方法，安装postgre数据库。

1）安装包信息及下载地址

Pg软件下载地址：http://ftp.postgresql.org/pub/source
Pg安装包名称  ：postgresql-11.0.tar.bz2
参考文档地址   ：https://www.postgresql.org/docs/10/installation.html

2）安装前系统检查,参照官方文档的要求，安装软件包

必须的安装包检查：
1：make --version检查
Eg:
[root@rhel6 ~]# make --version
GNU Make 3.81

2：gcc检查
[root@rhel6 ~]# rpm -aq gcc
gcc-4.4.7-4.el6.x86_64

可选软件包安装
1：Perl
2：Python
3：OpenSSL
......

3）解压安装包

tar -xjvf postgresql-11.0.tar.bz2 -C /usr/localEg：[root@rhel6 local]# cd postgresql-11.0/[root@rhel6 postgresql-11.0]# lltotal 744-rw-r--r-- 1 1107 1107 486 Oct 16 05:12 aclocal.m4drwxrwxrwx 2 1107 1107 4096 Oct 16 05:14 config-rwxr-xr-x 1 1107 1107 558874 Oct 16 05:12 configure-rw-r--r-- 1 1107 1107 83596 Oct 16 05:12 configure.indrwxrwxrwx 56 1107 1107 4096 Oct 16 05:14 contrib-rw-r--r-- 1 1107 1107 1192 Oct 16 05:12 COPYRIGHTdrwxrwxrwx 3 1107 1107 4096 Oct 16 05:14 doc-rw-r--r-- 1 1107 1107 3664 Oct 16 05:12 GNUmakefile.in-rw-r--r-- 1 1107 1107 284 Oct 16 05:12 HISTORY-rw-r--r-- 1 1107 1107 72717 Oct 16 05:15 INSTALL-rw-r--r-- 1 1107 1107 1682 Oct 16 05:12 Makefile-rw-r--r-- 1 1107 1107 1212 Oct 16 05:12 READMEdrwxrwxrwx 16 1107 1107 4096 Oct 16 05:15 src

4）编译

./configure

问题：
configure: error: readline library not found
If you have readline already installed, see config.log for details on the
failure.  It is possible the compiler isn't looking in the proper directory.
Use --without-readline to disable readline support.
原因：
The GNU Readline library is used by default. It allows psql (the PostgreSQL command line SQL interpreter) to remember each command you type, and allows you to use arrow keys to recall and edit previous commands. This is very helpful and is strongly recommended. If you don't want to use it then you must specify the --without-readline option to configure. As an alternative, you can often use the BSD-licensed libedit library, originally developed on NetBSD. The libedit library is GNU Readline-compatible and is used if libreadline is not found, or if --with-libedit-preferred is used as an option to configure. If you are using a package-based Linux distribution, be aware that you need both the readline and readline-devel packages, if those are separate in your distribution.
解决方法：
1：./configure --without-readline
2：安装readline包
rpm -ivh redline
rpm -ivh redline-devel

5）编译并安装

make && make install

6）创建postgre用户及相应数据目录

Useradd postgresSu - postgresmkdir -P /monkeys/pgsql11_data

7）数据库初始化：

/usr/local/pgsql/bin/initdb -D /monchickey/pgsql11_dataEg:[postgres@rhel6 bin]$ ./initdb -D /monchickey/pgsql11_dataThe files belonging to this database system will be owned by user "postgres".This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8".The default database encoding has accordingly been set to "UTF8".The default text search configuration will be set to "english".
Data page checksums are disabled.

第四章 Postgre数据库简单实用操作

---

在postgre数据库安装完成后，查看postgre数据库的后台进程，及端口信息来判断postgrep数据库的运行情况。进行简单操作，来尝试连接并使用数据库。

4.1 检查postgre数据库的进程及端口信息

1）查看postgre数据库进程

[postgres@rhel6 bin]$ ps -ef | grep postroot 1946 1 0 08:15 ? 00:00:00 /usr/libexec/postfix/masterpostfix 1954 1946 0 08:15 ? 00:00:00 pickup -l -t fifo -upostfix 1955 1946 0 08:15 ? 00:00:00 qmgr -l -t fifo -upostgres 3914 1 0 09:39 pts/0 00:00:00 /monchickey/pgsql/bin/postgres -D /monchickey/pgsql_datapostgres 3916 3914 0 09:39 ? 00:00:00 postgres: checkpointer process postgres 3917 3914 0 09:39 ? 00:00:00 postgres: writer process postgres 3918 3914 0 09:39 ? 00:00:00 postgres: wal writer process postgres 3919 3914 0 09:39 ? 00:00:00 postgres: autovacuum launcher process postgres 3920 3914 0 09:39 ? 00:00:00 postgres: stats collector process postgres 3921 3914 0 09:39 ? 00:00:00 postgres: bgworker: logical replication launcher

2）查看postgre端口，默认端口号是5432

[postgres@rhel6 ~]$ lsof -i:5432COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAMEpostgres 3914 postgres 3u IPv6 74137 0t0 TCP localhost:postgres (LISTEN)postgres 3914 postgres 4u IPv4 74138 0t0 TCP localhost:postgres (LISTEN)

3）查看psql的帮助信息

[postgres@rhel6 ~]$ psql --helppsql is the PostgreSQL interactive terminal.
Usage: psql [OPTION]... [DBNAME [USERNAME]]
General options: -c, --command=COMMAND run only single command (SQL or internal) and exit -d, --dbname=DBNAME database name to connect to (default: "postgres") -f, --file=FILENAME execute commands from file, then exit -l, --list list available databases, then exit -v, --set=, --variable=NAME=VALUE set psql variable NAME to VALUE (e.g., -v ON_ERROR_STOP=1) -V, --version output version information, then exit -X, --no-psqlrc do not read startup file (~/.psqlrc) -1 ("one"), --single-transaction execute as a single transaction (if non-interactive) -?, --help[=options] show this help, then exit --help=commands list backslash commands, then exit --help=variables list special variables, then exit
Input and output options: -a, --echo-all echo all input from script -b, --echo-errors echo failed commands -e, --echo-queries echo commands sent to server -E, --echo-hidden display queries that internal commands generate -L, --log-file=FILENAME send session log to file -n, --no-readline disable enhanced command line editing (readline) -o, --output=FILENAME send query results to file (or |pipe) -q, --quiet run quietly (no messages, only query output) -s, --single-step single-step mode (confirm each query) -S, --single-line single-line mode (end of line terminates SQL command)
Output format options: -A, --no-align unaligned table output mode -F, --field-separator=STRING field separator for unaligned output (default: "|") -H, --html HTML table output mode -P, --pset=VAR[=ARG] set printing option VAR to ARG (see \pset command) -R, --record-separator=STRING record separator for unaligned output (default: newline) -t, --tuples-only print rows only -T, --table-attr=TEXT set HTML table tag attributes (e.g., width, border) -x, --expanded turn on expanded table output -z, --field-separator-zero set field separator for unaligned output to zero byte -0, --record-separator-zero set record separator for unaligned output to zero byte
Connection options: -h, --host=HOSTNAME database server host or socket directory (default: "local socket") -p, --port=PORT database server port (default: "5432") -U, --username=USERNAME database user name (default: "postgres") -w, --no-password never prompt for password -W, --password force password prompt (should happen automatically)
For more information, type "\?" (for internal commands) or "\help" (for SQLcommands) from within psql, or consult the psql section in the PostgreSQLdocumentation.
Report bugs to <[e-mail]>.

5）psql中sql语法的帮助信息

[postgres@rhel6 bin]$ ./psql psql (11.0)Type "help" for help.
postgres=# \helpAvailable help: ABORT ALTER TEXT SEARCH TEMPLATE CREATE PUBLICATION DROP FUNCTION IMPORT FOREIGN ......

6）查看当前数据库列表：

postgres-# \l List of databases Name | Owner | Encoding | Collate | Ctype | Access privileges -----------+----------+----------+-------------+-------------+----------------------- postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres(3 rows)

7）创建数据库

postgres=# CREATE DATABASE dbname WITH OWNER=postgres ENCODING='UTF-8';CREATE DATABASE

8）切换数据库

postgres=# \c dbnameYou are now connected to database "dbname" as user "postgres".

9）查看数据库下所有表

dbname=# create table tab1 (id int,name char(20));CREATE TABLEdbname=# \d List of relations Schema | Name | Type | Owner --------+------+-------+---------- public | tab1 | table | postgres

10）查看表信息

dbname-# \d student Table "public.student" Column | Type | Collation | Nullable | Default --------+---------------+-----------+----------+--------- id | integer | | not null | name | character(32) | | | number | character(5) | | | Indexes: "student_pkey" PRIMARY KEY, btree (id)
