# 25.3、Docker 安装服务 ## 安装 `Microsoft SQL Server` ### 仓库地址 Docker Hub 文档： 微软官方文档： ### 安装脚本 ```bash docker pull mcr.microsoft.com/mssql/server ``` ### 运行脚本 ```bash [root@localhost ~]# docker run --name first-mssql -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=APJ.com!q1w2e3' -e 'MSSQL_PID=Express' -p 1433:1433 -d mcr.microsoft.com/mssql/server 38c3504d5c715e71e0912f85f084657f5a6696e51ed8c1309d87137ea77ab9db

0.0.0.0:1433->1433/tcp first-mssql [root@localhost ~]# ``` ### **进入服务环境** `docker exec -it container_id/name bash` ```bash [root@localhost ~]# docker exec -it first-mssql bash root@38c3504d5c71: ``` ### 连接数据库 **命令方式** ```bash [root@localhost ~]# docker exec -it first-mssql bash root@38c3504d5c71:/# /opt/mssql-tools/bin/sqlcmd -S localhost -U SA Password: 1> create database test_db 2> go 1> select

`mssql` 要求内存必须大于 ==3.5G== 😳 * 密码强度 `mssql` 要求密码必须至少为 8 个字符长，且包含三个以下四种字符集的字符：大写字母、 小写字母、 十进制数字和符号 😳 通过 `docker logs container_id/name` 可以查看具体错误日志 ### 实现多开 ```bash [root@localhost ~]# docker run --name two-mssql -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=APJ.com!q1w2e3' -e 'MSSQL_PID=Express' -p 8090:1433 -d mcr.microsoft.com/mssql/server 6860fb5d10237e4bd1931f46c80b4fb4ca33e77db61b50753e1fa999324483d2 [root@localhost ~]# ``` ### **Docker 环境中使用本地（宿主）数据库** 在docker环境中，如果想访问宿主的服务，比如`mssql`，`redis`，`mysql`等等就不能使用`localhost`，==`localhost`指的是docker环境中的地址，并非我们宿主的地址==，所以docker提供了其他模式来访问`本机（宿主）的localhost` * Mac/Windows `host.docker.internal`，这个就相当于我们的以前的`localhost` * Linux ![](/files/-M9bZb0pFoomjXulctNn) ## 安装 `Mysql` ### 安装脚本 ```bash docker pull mysql ``` ### 运行服务 ```bash [root@localhost ~]# docker run
