我是技术小白，安装Halo有一定的门槛，给同样是小白的同学分享一点经验！因为不是很懂Docker的机制，出了问题也不会修复！在这个前提下建议没有修改能力的同学，尽量只在Docker里面启动一个Halo的容器，并记好容器存储在宿主机文件里路径！其次就是数据库尽量不要用Docker的，因为我也没有备份数据库的习惯，并且数据库容器一单出现问题无法启动，那就面临无法找回的风险！所以我们可以选择外部数据库或者云数据库，这样不管是halo更新，还是halo容器因为各种奇奇怪怪的问题挂掉，可以重装Halo容器恢复到最后的状态！！ docker-compose.yml借鉴了论坛里不知道哪个提问帖子！需要的兄弟自取！每一行需要写什么都做了注释！ ```YAML version: "3" services: halo: #升级改下面halo:2.2.0这个版本号就OK！ image: halohub/halo:2.2.0 container_name: halo restart: on-failure:3 volumes: #修改/XXX/XXX/halo/.halo2的路径为本地你找的到的路径。里面会存主题、插件、好像还有文章具体我不是很懂，你能找到的位置就好。 #切记冒号后面的不要动！！！ - /XXX/XXX/halo/.halo2:/root/.halo2 ports: - "8090:8090" command: #修改ysql://XXX.XXX.XXX.XXX:3306/halodb，这是你外部数据库Mysql的地址，替换数据库IP或者域名都可以！端口号（3306）后面的是数据库名。 #嘿！兄弟记住这一行！一会儿下面说数据库的时候！记得回来看！！！我给这行起了个名字叫老六！！！ - --spring.r2dbc.url=r2dbc:pool:mysql://XXX.XXX.XXX.XXX:3306/halodb #下面sqlroot是数据库用户名，去你数据库里找。 - --spring.r2dbc.username=sqlroot #下面是数据库密码，不用我多BB了吧！ - --spring.r2dbc.password=xxxxxxxxxxxx #这是你用的数据库类型，用的啥就写啥！ - --spring.sql.init.platform=mysql #域名总有吧，最后用啥域名就在这填啥！要不进后台会有警告！别问我咋知道的！ - --halo.external-url=https://www.XXXXXXX.com/ #下面两个是初始管理员账号和密码！！写完记住！ - --halo.security.initializer.superadminusername=halo - --halo.security.initializer.superadminpassword=halo ``` 另外还有就是大家如果云服务器需要宿主机搭建Mysql,容器链接不上的可以看我博客 [https://www.pmbear.com/archives/1676139108419](https://www.pmbear.com/archives/1676139108419) 我也是小白正在慢慢摸索，大家有什么需要可以留言交流！！博客昨天刚弄好！！哈哈！以后慢慢写！

我按照你的操作的还是不能访问啊，mysql地址的也改成了docker0 的那个ip

我谷歌搜索,百度搜索找了半天没有找到任何部署方案终于找到了😄😄😄😄😄

@"InvoLve1"#p17985 hxd，你按照这个部署成功了吗？

@"Maverick"#p17987 你好，我已经按照楼主给的操作方法搭建Halo但还是无法连接Halo,因为我使用的是宿主数据库

@"InvoLve1"#p17988 正在查看报错信息

@"InvoLve1"#p17990 我的错误代码

InvoLve1 我的错误代码

InvoLve1

Maverick 你好，我的错误代码，也是这样子

Maverick

InvoLve1 hxd 有解决办法吗？

xiaoxiongbaba

InvoLve1
你们俩去我博客看，有一步需要在数据库设置Docker的IP地址

xiaoxiongbaba

Maverick

xiaoxiongbaba

Maverick
还有就是你发的这个错误代码我看不懂，如果按照我这个配置你还是不能访问halo的话！首先需要排除几个问题。
1.先将mysql的访问权限更改成ALL，就是所有人都可以链接数据库。尝试是否可以打开。
2.方法1无法解决的话，检查docker-compose.yml是否填写正确。检查数据库名，数据库用户，数据库密码是否正确。
3.全部正确的话，检查服务器是否放行了8090端口。
如果还不能访问你就再回复我，我睡醒可以指导你一下。

InvoLve1

xiaoxiongbaba 经过一晚上的研究，终于可以了十分感谢这个教程

Maverick

xiaoxiongbaba hxd,全部试了一下呀，都按照你上面说的，还是无法启动

xiaoxiongbaba

InvoLve1
只要细心一点，大概也就那几个问题，毕竟也不用写代码！！！

xiaoxiongbaba

InvoLve1
数据库最后一定要把ALL权限关掉！！毕竟不安全！

InvoLve1

Maverick 你好,请问您是否使用宝塔面板进行安装的？

InvoLve1

InvoLve1 如果是使用宝塔面板安装，请把那个服务器的mysql端口3306和宝塔安全的端口也要放开

Maverick

InvoLve1 是的呀，是使用了宝塔面板

Maverick

InvoLve1 谢谢hxd，原来是宝塔的那个端口没放开，一直没注意这个问题

InvoLve1

Maverick 然后再把数据库的root用户密码改一下，还有你想用的数据库密码也改一下，然后在那个给数据库重新启动一下

InvoLve1

InvoLve1 那如果没问题，那就不用执行这一步了
