Docker部署postgresql-11以及主从配置

---

一. Docker部署postgresql-11（简单版）

1. 拉取镜像

docker pull docker.io/postgres:11

2.启动命令脚本

vi startPostgres.sh

填入以下内容：

docker run -d --name postgresql-11 \
--restart=always  \
-v /postgresql/data:/var/lib/postgresql/data \
-e POSTGRES_PASSWORD=123456 \
-p 5432:5432 \
docker.io/postgres:11

3.给脚本写权限：

chmod +x startPostgres.sh

4.执行启动脚本：

./startPostgres.sh

5.查看日志,启动报错：

docker logs postgresql-11

2019-06-13 12:35:21.977 UTC [1] FATAL:  configuration file "/var/lib/postgresql/data/postgresql.conf" contains errors

2019-06-13 12:35:23.182 UTC [1] LOG:  invalid value for parameter "lc_time": "zh_CN.UTF-8"

6.在容器中安装中文编码：

>>docker exec -it postgresql-11 /bin/bash
1、root@9a36f3d4c0e9:/# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 9 (stretch)"
NAME="Debian GNU/Linux"

VERSION="9 (stretch)"
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"


 
2、debian下安装 locale 并设置 zh_CN.UTF-8
root@9a36f3d4c0e9:/# apt-get install locales

7.重启动docker容器：
