# postgresql容器搭建 #

## 一、镜像安装 ##

docker pull postgres

## 二、镜像部署 ##

首先创建宿主机文件夹,因为docker是root权限，它自己创建的文件夹也是root权限才能访问。如果登录用户拥有最高权限可以不用手动创建文件夹。

1.  创建文件夹

## 配置文件夹
    mkdir /opt/data-postgres/postgresql_config/
    ## 数据文件夹
    mkdir /opt/data-postgres/postgresql

1.  导入自定义配置文件  
    将自定义配置放入配置文件夹中(配置文件见下面)。
2.  安装容器，并挂载数据文件

docker run 
    --name postgres -d 
    -p 5432:5432 
    --restart always 
    -e POSTGRES_PASSWORD=*** 
    -e PGDATA=/var/lib/postgresql/data 
    -e POSTGRES_USER=admin 
    -v /opt/data-postgres/postgresql_config/my-postgres.conf:/etc/postgresql/postgresql.conf 
    -v /opt/data-postgres/postgresql:/var/lib/postgresql/data
    postgres 
    -c config_file=/etc/postgresql/postgresql.conf

注：使用请删除换行

PGDATA=/var/lib/postgresql/data :指定数据文件在容器中的位置  
POSTGRES\_PASSWORD :指定密码

## 三、my-postgres.conf 配置内容 ##

配置文件主要配置一下内容:  
a.设置时区为北京时区

如何获取官方推荐的配置文件设置方法？  
[https://hub.docker.com/\_/postgres][https_hub.docker.com_postgres]  
查找:**Database Configuration**

配置文件获取方法(从里面复制出来的);

$ # get the default config 获取默认配置
    $ docker run -i --rm postgres cat /usr/share/postgresql/postgresql.conf.sample > my-postgres.conf
    
    $ # customize the config
    
    $ # run postgres with custom config 
    $ docker run -d --name some-postgres -v "$PWD/my-postgres.conf":/etc/postgresql/postgresql.conf postgres -c 'config_file=/etc/postgresql/postgresql.conf'

ps:采用上述方法得到的配置就是下面这个，都被注释掉了；只是在最后加了点自定义配置

# -----------------------------
    # PostgreSQL configuration file
    # -----------------------------
    #
    # This file consists of lines of the form:
    #
    #   name = value
    #
    # (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
    # "#" anywhere on a line.  The complete list of parameter names and allowed
    # values can be found in the PostgreSQL documentation.
    #
    # The commented-out settings shown in this file represent the default values.
    # Re-commenting a setting is NOT sufficient to revert it to the default value;
    # you need to reload the server.
    #
    # This file is read on server startup and when the server receives a SIGHUP
    # signal.  If you edit the file on a running system, you have to SIGHUP the
    # server for the changes to take effect, run "pg_ctl reload", or execute
    # "SELECT pg_reload_conf()".  Some parameters, which are marked below,
    # require a server shutdown and restart to take effect.
    #
    # Any parameter can also be given as a command-line option to the server, e.g.,
    # "postgres -c log_connections=on".  Some parameters can be changed at run time
    # with the "SET" SQL command.
    #
    # Memory units:  kB = kilobytes        Time units:  ms  = milliseconds
    #                MB = megabytes                     s   = seconds
    #                GB = gigabytes                     min = minutes
    #                TB = terabytes                     h   = hours
    #                                                   d   = days
