1、linux 7 安装 PG12.5
1.1、下载源码包
Postgresql
https://www.postgresql.org/ftp/source/v12.5/
1.2、依赖包安装
yum -y install coreutils glib2 lrzsz dstat sysstat e4fsprogs xfsprogs ntp readline-devel zlib-devel openssl-devel pam-devel libxml2-devel libxslt-devel python-devel tcl-devel gcc gcc-c++ make smartmontools flex bison perl-devel perl-ExtUtils* openldap-devel jadetex openjade bzip2
1.3、创建用户和目录
mkdir -p /pg/pg12.5
mkdir -p /pg/pg12.5_data
useradd pg
passwd pg
chown pg:pg /pg -R
1.4、环境变量
export PS1="[`hostname`][\$LOGNAME][\$PWD]$"
export LANG=en_US.utf8
export PG_HOME=/pg/pg12.5
export PG_DATA=/pg/pg12.5_data
export PATH=$PG_HOME/bin:$PATH:
export MANPATH=$PG_HOME/share/man:$MANPATH
export LD_LIBRARY_PATH=$PG_HOME/lib:/lib64:/usr/lib64:/usr/local/lib64:/lib:/usr/lib:/usr/local/lib:$LD_LIBRARY_PATH
#export PGHOST=$PG_DATA
#export PGUSER=postgres
#export PG_DATABASE=postgres
#export PGPORT=1921
1.5、编译安装
tar zxf postgresql-12.5.tar.gz
cd postgresql-12.5/
./configure --prefix=/pg/pg12.5
make && make install
[pg][/pg/pg12.5]$psql -V
psql (PostgreSQL) 12.
如果在configure的时候报错
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.
解决办法：
sudo yum install -y readline-devel
1.6、初始化数据库
initdb -D /pg/pg12.5_data -U postgres --lc-collate=C --lc-ctype=en_US.UTF-8-E UTF8
初始化的时候 $PG_HOME/share/postgresql/postgres.bki 存了初始化元数据的内容
参数说明：
[pg][/pg/pg12.5]$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
-g, --allow-group-access allow group read/execute on data directory
--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, --waldir=WALDIR location for the write-ahead log directory
--wal-segsize=SIZE size of WAL segments, in megabytes
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, --no-clean do not clean up after errors
-N, --no-sync 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.

1.7、启动数据库
pg_ctl -D /pg/pg12.5_data -l /pg/pg12.5_data/log/postgresql.log start
参数说明：
[pg][/pg/pg12.5]$pg_ctl --help
pg_ctl is a utility to initialize, start, stop, or control a PostgreSQL server.
Usage:
pg_ctl init[db] [-D DATADIR] [-s] [-o OPTIONS]
pg_ctl start [-D DATADIR] [-l FILENAME] [-W] [-t SECS] [-s]
[-o OPTIONS] [-p PATH] [-c]
pg_ctl stop [-D DATADIR] [-m SHUTDOWN-MODE] [-W] [-t SECS] [-s]
pg_ctl restart [-D DATADIR] [-m SHUTDOWN-MODE] [-W] [-t SECS] [-s]
[-o OPTIONS] [-c]
pg_ctl reload [-D DATADIR] [-s]
pg_ctl status [-D DATADIR]
pg_ctl promote [-D DATADIR] [-W] [-t SECS] [-s]
pg_ctl logrotate [-D DATADIR] [-s]
pg_ctl kill SIGNALNAME PID
Common options:
-D, --pgdata=DATADIR location of the database storage area
-s, --silent only print errors, no informational messages
-t, --timeout=SECS seconds to wait when using -w option
-V, --version output version information, then exit
-w, --wait wait until operation completes (default)
-W, --no-wait do not wait until operation completes
-?, --help show this help, then exit
If the -D option is omitted, the environment variable PGDATA is used.
Options for start or restart:
-c, --core-files allow postgres to produce core files
-l, --log=FILENAME write (or append) server log to FILENAME
-o, --options=OPTIONS command line options to pass to postgres
(PostgreSQL server executable) or initdb
-p PATH-TO-POSTGRES normally not necessary
Report bugs to <[email protected]>.
1.8、关闭数据库
pg_ctl stop -D /pg/pg12.5_data/ -m fast
Options for stop or restart:
-m, --mode=MODE MODE can be "smart", "fast", or "immediate"
Shutdown modes are:
smart quit after all clients have disconnected
fast quit directly, with proper shutdown (default)
immediate quit without complete shutdown; will lead to recovery on restart
Allowed signal names for kill:
ABRT HUP INT KILL QUIT TERM USR1 USR2
1.9、进程说明
ps -ef|grep postgres
pg 79357 1 0 15:33 ? 00:00:00 /pg/pg12.5/bin/postgres -D /pg/pg12.5_data

2、Windows 安装 PG12.5
2.1、重启服务
pg_ctl start -D G:\PostgreSQL\12\data
pg_ctl stop -D G:\PostgreSQL\12\data -m fast
2.2、修改为英文
编辑数据文件下的 postgresql.conf
# These settings are initialized by initdb, but they can be changed.
lc_messages = 'Chinese (Simplified)_China.936' # locale for system error message
# strings
lc_monetary = 'Chinese (Simplified)_China.936' # locale for monetary formatting
lc_numeric = 'Chinese (Simplified)_China.936' # locale for number formatting
lc_time = 'Chinese (Simplified)_China.936' # locale for time formatting
# default configuration for text search
default_text_search_config = 'pg_catalog.simple'
# These settings are initialized by initdb, but they can be changed.
lc_messages = 'en_US.utf8' # locale for system error message
# strings
lc_monetary = 'en_US.utf8' # locale for monetary formatting
lc_numeric = 'en_US.utf8' # locale for number formatting
lc_time = 'en_US.utf8' # locale for time formatting
# default configuration for text search
default_text_search_config = 'pg_catalog.english'
3、Mac安装 PG13.3
3.1、通过brew安装数据库，默认安装最新版本
brew list postgresql
brew install postgresql
3.2、查看下安装的版本
rhl@rhldeMacBook-Pro log % pg_ctl -V
pg_ctl (PostgreSQL) 13.3
3.3、初始化数据库
rhl@rhldeMacBook-Pro ~ % initdb -D /Users/rhl/other/postgresql -U rhl --lc-collate=C --lc-ctype=en_US.UTF-8 --lc-messages=en_US.UTF-8 -E UTF8
The files belonging to this database system will be owned by user "rhl".
This user must also own the server process.
The database cluster will be initialized with locales
COLLATE: C
CTYPE: en_US.UTF-8
MESSAGES: en_US.UTF-8
MONETARY: zh_CN.UTF-8
NUMERIC: zh_CN.UTF-8
TIME: zh_CN.UTF-8
The default text search configuration will be set to "english".
Data page checksums are disabled.

selecting dynamic shared memory implementation ... posix
selecting default max_connections ... 100

initdb: 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 /Users/rhl/other/postgresql -l logfile start
3.4、修改配置文件
vi postgresql.conf
listen_addresses = '0.0.0.0'
port = 5432
log_destination = 'csvlog'
logging_collector = on
log_directory = 'log'
log_filename = 'postgresql-%a.log'
log_truncate_on_rotation = on
log_rotation_age = 1d
log_rotation_size = 1GB
3.5、启动数据库
pg_ctl -D /Users/rhl/other/postgresql start
ps -ef|grep postgres
3.6、创建user
createdb
rhl@rhldeMacBook-Pro var % psql
psql (13.3)
Type "help" for help.
rhl=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+-------+----------+---------+-------------+-------------------
postgres | rhl | UTF8 | C | en_US.UTF-8 |
rhl | rhl | UTF8 | C | en_US.UTF-8 |
template0 | rhl | UTF8 | C | en_US.UTF-8 | =c/rhl +
| | | | | rhl=CTc/rhl
template1 | rhl | UTF8 | C | en_US.UTF-8 | =c/rhl +
| | | | | rhl=CTc/rhl
(4 rows)
可以看到已存在用户同名数据库、postgres数据库、template0、template1，但是postgres数据库的所有者是当前用户，没有postgres用户。所以我们需要创建postgres用户。
CREATE USER postgres WITH PASSWORD 'postgres';
GRANT ALL PRIVILEGES ON DATABASE postgres to postgres;
ALTER ROLE postgres CREATEDB;
DROP DATABASE postgres;
CREATE DATABASE postgres OWNER postgres;
psql -U postgres -d postgres
