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_64-redhat-linux-gnu
Copyright © 2010 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later http://gnu.org/licenses/gpl.html
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.
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_64
[root@cs1 /]# rpm -aq | grep readline-deve
readline-devel-6.2-9.el7.x86_64
[root@cs1 /]# rpm -aq | grep libedit
libedit-3.0-12.20121213cvs.el7.x86_64
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
[root@cs1 local]# ls -lrt

8.安装
root@cs1 local]# cd pgsql
8.1安装过程的第一步就是为你的系统配置源代码树并选择你喜欢的选项。这个工作是通过运行configure脚本实现的,对于默认安装,你只需要简单地输入:
[root@cs1 pgsql]# ./configure
checking build system type… x86_64-pc-linux-gnu
…省略…
configure: using CPPFLAGS= -D_GNU_SOURCE
configure: using LDFLAGS= -Wl,–as-needed
configure: creating ./config.status
config.status: creating GNUmakefile
config.status: creating src/Makefile.global
config.status: creating src/include/pg_config.h
config.status: creating src/include/pg_config_ext.h
config.status: creating src/interfaces/ecpg/include/ecpg_config.h
config.status: linking src/backend/port/tas/dummy.s to src/backend/port/tas.s
config.status: linking src/backend/port/dynloader/linux.c to src/backend/port/dynloader.c
config.status: linking src/backend/port/sysv_sema.c to src/backend/port/pg_sema.c
config.status: linking src/backend/port/sysv_shmem.c to src/backend/port/pg_shmem.c
config.status: linking src/backend/port/dynloader/linux.h to src/include/dynloader.h
config.status: linking src/include/port/linux.h to src/include/pg_config_os.h
config.status: linking src/makefiles/Makefile.linux to src/Makefile.port
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=
P
A
T
H
:
PATH:
PATH:HOME/.local/bin:$HOME/bin
export PATH
export LD_LIBRARY_PATH=/usr/local/pgsql/lib
export PG_HOME=/usr/local/pgsql
export PATH=
P
G
H
O
M
E
/
b
i
n
/
:
PG_HOME/bin/:
PGH OME/bin/:PATH
export PGDATA=/usr/local/pgsql/data
10.初始化数据库
使用pgsql用户来执行
[pgsql@cs1 ~]$ 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-bugs@postgresql.org.
[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

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

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
