win10下docker啓動postgres

一、拉取鏡像

docker pull postgres:13

二、簡單版啓動容器

1. 執行命令啓動容器

docker run --name postgres -e POSTGRES_PASSWORD=1234 -p 5433:5432 -d postgres:13

2. 打開navicat查看結果

從以上結果看出數據庫連接成功 

3. 拷貝鏡像默認配置到宿主機

docker cp postgres:/var/lib/postgresql/data/postgresql.conf d:/usr/share/postgresql/postgresql.conf

 

4. 查看配置文件，刪除掉註釋行後，鏡像默認配置的結果如下

listen_addresses = '*'
					
# port = 5432				# (change requires restart)
max_connections = 100			# (change requires restart)

shared_buffers = 128MB			# min 128kB

dynamic_shared_memory_type = posix	# the default is the first option

max_wal_size = 1GB
min_wal_size = 80MB

log_timezone = 'Etc/UTC'

datestyle = 'iso, mdy'
timezone = 'Etc/UTC'

# These settings are initialized by initdb, but they can be changed.
lc_messages = 'en_US.utf8'			# locale for system error message
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'

5. 刪除容器 

docker rm -f postgres

三、複雜版啓動容器

1. 在D:\usr\bin目錄下創建docker-compose-postgres.yml文件

version: '3.1'

services:
  # 服務器名
  db:
    image: postgres:13
    container_name: postgres
    # restart: always
    # 從指定配置文件啓動
    command: -c 'config_file=/etc/postgresql/postgresql.conf'
    volumes:
        - pgdata:/var/lib/postgresql/data
        - /d/usr/share/postgresql/log:/var/log/postgresql
        # # 配置文件默認路徑 /var/lib/postgresql/data/postgresql.conf
        - /d/usr/share/postgresql/my-postgres.conf:/etc/postgresql/postgresql.conf
    environment:
      POSTGRES_USER: test
      POSTGRES_PASSWORD: test
      POSTGRES_DB: test
    ports:
      - 5433:5432
      
  adminer:
    image: adminer:4.7.7-standalone
    container_name: adminer
    # restart: always
    ports:
      - 8080:8080
volumes:
  pgdata:
     external: true

2. 在D:\usr\bin目錄下創建postgres啓動腳本postgres-up.sh

#!/bin/bash

docker-compose -f d:/usr/bin/docker-compose-postgres.yml up

3. 在目錄下D:\usr\share\postgresql創建配置文件my-postgres.conf

listen_addresses = '*'
					
# port = 5432				# (change requires restart)
max_connections = 100			# (change requires restart)

shared_buffers = 128MB			# min 128kB

dynamic_shared_memory_type = posix	# the default is the first option

max_wal_size = 1GB
min_wal_size = 80MB

log_timezone = 'Etc/UTC'

datestyle = 'iso, mdy'
timezone = 'Etc/UTC'

# These settings are initialized by initdb, but they can be changed.
lc_messages = 'en_US.utf8'			# locale for system error message
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'

 4. 手動創建數據卷

docker volume create --name=pgdata

5. 切換到postgres-up.sh腳本腳本所在目錄，執行腳本命令

cd d:/usr/bin
./postgres-up.sh

 

6. 查看結果 

從以上結果可以看出配置成功

四、日誌配置

1. 配置文件my-postgres.conf新增內容

logging_collector = on
log_destination = 'stderr'
log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'
log_directory = '/var/log/postgresql'
log_statement = all	 #需設置跟蹤所有語句，否則只能跟蹤出錯信息，有4種類型：none(默認), ddl, mod, all
log_min_duration_statement = 5000	#milliseconds,記錄執行5秒及以上的語句

2. 重啓容器

./postgres-up.sh

3. 執行錯誤查詢語句生成日誌

# 正確表名爲pg_stat_activity
select * from pg_stat_activity1 where state<>'idle' and now()-query_start > interval '1 s' order by query_start

 

4. 查看D:\usr\share\postgresql\log目錄下日誌文件內容

到此日誌配置成功
