在Oracle Linux 7.1中使用源码来安装PostgreSQL 9.6

原创 PostgreSQL 作者:eric0435 时间:2019-06-04 19:27:30 0 删除 编辑

在Oracle Linux 7.1中使用源码来安装PostgreSQL 9.6

编译PostgreSQL需要下列软件包:

1.GUN make版本3.80或新的要求。

[root@cs1 /]# make --version

GNU Make 3.82

Built for x86-redhat-linux-gnu

Copyright (C) 2010  Free Software Foundation, Inc.

License GPLv3+: GNU GPL version 3 or later 

This is free software: you are free to change and redistribute it.

There is NO WARRANTY, to the extent permitted by law.

2.需要一个ISO/ANSI C 编译器(至少是 C89兼容的)。我们推荐使用最近版本的GCC

[root@cs1 /]# gcc --version

gcc (GCC) 4.8.3 20140911 (Red Hat 4.8.3-9)

Copyright (C) 2013 Free Software Foundation, Inc.

本程序是自由软件;请参看源代码的版权声明。本软件没有任何担保;

包括没有适销性和某一专用目的下的适用性担保。

3.除了gzip和bzip2之外,我们还需要tar来解包源代码发布。

4.GNU Readline库

[root@cs1 /]# rpm -aq | grep readline

readline-6.2-9.el7.x86[root@cs1 /]# rpm -aq | grep readline-deve

readline-devel-6.2-9.el7.x86[root@cs1 /]# rpm -aq | grep libedit

libedit-3.0-12.20121213cvs.el7.x86

5.可选工具包在默认配置的时候并不要求它们,但是如果打开了一些编译选项之后就需要它们了

perl 5.8 or later

python

Kerberos

OpenSSL

OpenLDAP and/or PAM

Flex 2.5.31 or later

Bison 1.875 or later

6.创建用户与组

[root@cs1 local]# groupadd pgsql

[root@cs1 local]# useradd -g pgsql pgsql

7.下载源码包postgresql-9.6.6.tar.gz并上传到服务器并解压

[root@cs1 local]# gunzip  mariadb-10.0.38-linux-glibc_214-x86

创建一个软链接

[root@cs1 local]# ln -s postgresql-9.6.6 pgsql

[root@cs1 local]# ls -lrt

默认安装目录/usr/local/pgsql,可以使用--prefix=path进行修改,./configure --help

8.2 编译

要开始编译,键入:

root@cs1 local]# make

(一定要记得用GNU make)。依你的硬件而异,编译过程可能需要 5 分钟到半小时。显示的最后一行应该是:

All of PostgreSQL successfully made. Ready to install.

如果你希望编译所有能编译的东西,包括文档(HTML和手册页)以及附加模块(contrib),这样键入:

[root@cs1 pgsql]# make world

.....省略.....

make[2]: 离开目录“/usr/local/postgresql-9.6.6/contrib/vacuumlo”

make[1]: 离开目录“/usr/local/postgresql-9.6.6/contrib”

PostgreSQL, contrib, and documentation successfully made. Ready to install.

8.3安装文件

要安装PostgreSQL,输入:

make install

这条命令将把文件安装到在步骤 1中指定的目录。确保你有足够的权限向该区域写入。通常你需要用 root 权限做这一步。或者你也可以事先创建目标目录并且分派合适的权限。

要安装文档(HTML和手册页),输入:

make install-docs

如果你按照上面的方法编译了所有东西,输入:

make install-world

这也会安装文档。

[root@cs1 pgsql]# make install-world

......省略....

make[2]: 离开目录“/usr/local/postgresql-9.6.6/contrib/vacuumlo”

make[1]: 离开目录“/usr/local/postgresql-9.6.6/contrib”

PostgreSQL, contrib, and documentation installation complete.

9.设置环境变量

创建目录/usr/local/pgsql/data用来存放数据

[root@cs1 pgsql]# mkdir /usr/local/pgsql/data

[root@cs1 pgsql]# chown pgsql:pgsql data


[root@cs1 pgsql]# su - pgsql

[pgsql@cs1 ~]$ vi .bash_profile

# .bash_profile


# Get the aliases and functions

if [ -f ~/.bashrc ]; then

        . ~/.bashrc

fi


# User specific environment and startup programs


PATH=$PATH:$HOME/.local/bin:$HOME/bin


export PATH

export LD_LIBRARY_PATH=/usr/local/pgsql/lib

export PG_HOME=/usr/local/pgsql

export PATH=$PG_HOME/bin/:$PATH

export PGDATA=/usr/local/pgsql/data

10.初始化数据库

使用pgsql用户来执行

[pgsql@cs1 ~]$ initdb --help

initdb initializes a PostgreSQL database cluster.


Usage:

  initdb [OPTION]... [DATADIR]


Options:

  -A, --auth=METHOD         default authentication method for local connections

      --auth-host=METHOD    default authentication method for local TCP/IP connections

      --auth-local=METHOD   default authentication method for local-socket connections

 [-D, --pgdata=]DATADIR     location for this database cluster

  -E, --encoding=ENCODING   set default encoding for new databases

      --locale=LOCALE       set default locale for new databases

      --lc-collate=, --lc-ctype=, --lc-messages=LOCALE

      --lc-monetary=, --lc-numeric=, --lc-time=LOCALE

                            set default locale in the respective category for

                            new databases (default taken from environment)

      --no-locale           equivalent to --locale=C

      --pwfile=FILE         read password for the new superuser from file

  -T, --text-search-config=CFG

                            default text search configuration

  -U, --username=NAME       database superuser name

  -W, --pwprompt            prompt for a password for the new superuser

  -X, --xlogdir=XLOGDIR     location for the transaction log directory


Less commonly used options:

  -d, --debug               generate lots of debugging output

  -k, --data-checksums      use data page checksums

  -L DIRECTORY              where to find the input files

  -n, --noclean             do not clean up after errors

  -N, --nosync              do not wait for changes to be written safely to disk

  -s, --show                show internal settings

  -S, --sync-only           only sync data directory


Other options:

  -V, --version             output version information, then exit

  -?, --help                show this help, then exit


If the data directory is not specified, the environment variable PGDATA

is used.


Report bugs to .

[pgsql@cs1 ~]$ initdb -D /usr/local/pgsql/data

The files belonging to this database system will be owned by user "pgsql".

This user must also own the server process.


The database cluster will be initialized with locale "zh_CN.gb2312".

The default database encoding has accordingly been set to "EUC_CN".

initdb: could not find suitable text search configuration for locale "zh_CN.gb2312"

The default text search configuration will be set to "simple".


Data page checksums are disabled.


fixing permissions on existing directory /usr/local/pgsql/data ... ok

creating subdirectories ... ok

selecting default max_connections ... 100

selecting default shared_buffers ... 128MB

selecting dynamic shared memory implementation ... posix

creating configuration files ... ok

running bootstrap script ... ok

performing post-bootstrap initialization ... ok

syncing data to disk ... ok


WARNING: enabling "trust" authentication for local connections

You 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 /usr/local/pgsql/data -l logfile start

同时在pgsql的目录可以看到生成的数据目录data以及该目录的相关数据和配置文件:

[root@cs1 soft]# cd /usr/local/pgsql

[root@cs1 pgsql]# ls -lrt

11.启动数据库

在初始化数据库结束后看到了启动命令:

Success. You can now start the database server using:


    pg_ctl -D /usr/local/pgsql/data -l logfile start

[pgsql@cs1 ~]$ echo $PGDATA

/usr/local/pgsql/data

由于我们设置了环境变量,所以已经指定了数据目录PGDATA, -l表示日志文件目录,通常需要指定,所以我们在/usr/local/pgsql根目录下再创建一个log目录用来存放日志文件(注意别忘记赋予可写的权限)

[root@cs1 pgsql]# chown -R pgsql:pgsql log

[root@cs1 pgsql]# chmod -R 775 log

[root@cs1 pgsql]# ls -lrt

运行pg_ctl start -l /usr/local/pgsql/log/pg_server.log即可启动数据库

[pgsql@cs1 ~]$ pg_ctl start -l /usr/local/pgsql/log/pg_server.log

server starting

通过ps -ef|grep postgres查看一下postgres相关是否存在相关进程

[root@cs1 log]# ps -ef|grep postgres

pgsql     4977     1  0 22:05 pts/3    00:00:00 /usr/local/postgresql-9.6.6/bin/postgres

pgsql     4980  4977  0 22:05 ?        00:00:00 postgres: checkpointer process   

pgsql     4981  4977  0 22:05 ?        00:00:00 postgres: writer process   

pgsql     4982  4977  0 22:05 ?        00:00:00 postgres: wal writer process   

pgsql     4983  4977  0 22:05 ?        00:00:00 postgres: autovacuum launcher process   

pgsql     4984  4977  0 22:05 ?        00:00:00 postgres: stats collector process   

root      5145 15622  0 22:06 pts/4    00:00:00 grep --color=auto postgres

从数据库日志文件可以看到如下信息:

[root@cs1 log]# tail -f pg_server.log 

LOG:  database system was shut down at 2019-06-04 21:56:12 CST

LOG:  MultiXact member wraparound protections are now enabled

LOG:  database system is ready to accept connections

LOG:  autovacuum launcher started

12.连接数据库

[pgsql@cs1 ~]$ psql --list

                               List of databases

   Name    | Owner | Encoding |   Collate    |    Ctype     | Access privileges 

-----------+-------+----------+--------------+--------------+-------------------

 postgres  | pgsql | EUC_CN   | zh_CN.gb2312 | zh_CN.gb2312 | 

 template0 | pgsql | EUC_CN   | zh_CN.gb2312 | zh_CN.gb2312 | =c/pgsql         +

           |       |          |              |              | pgsql=CTc/pgsql

 template1 | pgsql | EUC_CN   | zh_CN.gb2312 | zh_CN.gb2312 | =c/pgsql         +

           |       |          |              |              | pgsql=CTc/pgsql

(3 rows)

启动成功后我们就可以通过postgresql自带的客户端工具psql来进行连接,直接输入psql看到版本信息则说明连接成功:

[pgsql@cs1 ~]$ psql postgres

psql (9.6.6)

Type "help" for help.


postgres=#

接下来要做的第一件事就是设置postgres用户的密码(默认为空),用psql连接成功后直接输入\password即会提示输入两次密码

[pgsql@cs1 ~]$ psql postgres

psql (9.6.6)

Type "help" for help.


postgres=# \password

Enter new password: 

Enter it again: 

postgres=# \l

                               List of databases

   Name    | Owner | Encoding |   Collate    |    Ctype     | Access privileges 

-----------+-------+----------+--------------+--------------+-------------------

 postgres  | pgsql | EUC_CN   | zh_CN.gb2312 | zh_CN.gb2312 | 

 template0 | pgsql | EUC_CN   | zh_CN.gb2312 | zh_CN.gb2312 | =c/pgsql         +

           |       |          |              |              | pgsql=CTc/pgsql

 template1 | pgsql | EUC_CN   | zh_CN.gb2312 | zh_CN.gb2312 | =c/pgsql         +

           |       |          |              |              | pgsql=CTc/pgsql

(3 rows)



postgres=# \l

                               List of databases

   Name    | Owner | Encoding |   Collate    |    Ctype     | Access privileges 

-----------+-------+----------+--------------+--------------+-------------------

 postgres  | pgsql | EUC_CN   | zh_CN.gb2312 | zh_CN.gb2312 | 

 template0 | pgsql | EUC_CN   | zh_CN.gb2312 | zh_CN.gb2312 | =c/pgsql         +

           |       |          |              |              | pgsql=CTc/pgsql

 template1 | pgsql | EUC_CN   | zh_CN.gb2312 | zh_CN.gb2312 | =c/pgsql         +

           |       |          |              |              | pgsql=CTc/pgsql

(3 rows)


postgres=# select version();

                                                 version                                                 

---------------------------------------------------------------------------------------------------------

 PostgreSQL 9.6.6 on x86-pc-linux-gnu, compiled by gcc (GCC) 4.8.3 20140911 (Red Hat 4.8.3-9), -bit

(1 row)


postgres=# select current_date;

    date    

------------

 2019-06-04

(1 row)


postgres=#

到此使用源码来安装pg数据库就完成了。
