   ]
   
   

   重点信息: "Subnet": "172.17.0.0/16"、"IPv4Address": "172.17.0.3/16"

2. 创建自定义网络并指定网段

   [root@10-7-176-211 ~]# docker network create -d bridge --subnet 192.168.0.0/16 --gateway 192.168.0.1 halo-net
   4257e42bbf3bb64ec39544a5a6ba49a345df556400f3d8ec36099c59f09539eb
   [root@10-7-176-211 ~]# docker network ls
   NETWORK ID     NAME              DRIVER    SCOPE
   e7660459253e   bridge            bridge    local
   4ca31df30e45   example_default   bridge    local
   4257e42bbf3b   halo-net          bridge    local
   63d1d72302da   host              host      local
   f1ef8995ba94   none              null      local
   

   -d: 指定驱动，网络类型

   –subnet: 指定子网网段

   –gateway: 指定子网网关

   halo-net: 网络名称

3. 查看新建的网络详情

   [root@10-7-176-211 ~]# docker network inspect halo-net
   [
       {
           "Name": "halo-net",
           "Id": "4257e42bbf3bb64ec39544a5a6ba49a345df556400f3d8ec36099c59f09539eb",
           "Created": "2022-02-20T19:49:49.295905019+08:00",
           "Scope": "local",
           "Driver": "bridge",
           "EnableIPv6": false,
           "IPAM": {
               "Driver": "default",
               "Options": {},
               "Config": [
                   {
                       "Subnet": "192.168.0.0/16",
                       "Gateway": "192.168.0.1"
                   }
               ]
           },
           "Internal": false,
           "Attachable": false,
           "Ingress": false,
           "ConfigFrom": {
               "Network": ""
           },
           "ConfigOnly": false,
           "Containers": {},
           "Options": {},
           "Labels": {}
       }
   ]
   

   重点: "Subnet": "192.168.0.0/16"、"Gateway": "192.168.0.1"以及容器情况，现在没有任何容器链接到该网络，所以是空的: "Containers": {}

Docker安装MySql

1. 创建mysql宿主目录

   [root@10-7-176-211 opt]# mkdir -p /opt/halo/mysql
   

2. 运行Docker命令创建Mysql容器

   [root@10-7-176-211 opt]# docker run --name some-mysql -v /opt/halo/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw --net halo-net --restart=unless-stopped -d mysql/mysql-server
   [root@10-7-176-211 opt]# docker ps -a
   CONTAINER ID   IMAGE                    COMMAND                  CREATED          STATUS                             PORTS    NAMES
   11d199640bb7   mysql/mysql-server       "/entrypoint.sh mysq…"   25 seconds ago   Up 24 seconds (health: starting)   3306/tcp, 33060-33061/tcp      some-mysql
   
   

3. 进入容器

   [root@10-7-176-211 opt]# docker exec -it some-mysql /bin/bash
   bash-4.4#
   

4. 在容器中增加用户admin，指定host为halo容器的IP，并授权admin用户

   mysql> use mysql;
   Reading table information for completion of table and column names
   You can turn off this feature to get a quicker startup with -A
   
   Database changed
   mysql> create user 'admin'@'192.168.0.3' identified by 'my-secret-pw';
   Query OK, 0 rows affected (0.01 sec)
   
   mysql> grant all on *.* to 'admin'@'192.168.0.3';
   Query OK, 0 rows affected (0.00 sec)
   
   mysql> flush privileges;
   Query OK, 0 rows affected (0.00 sec)
   
   mysql> select host, user from user where user='admin';
   +-------------+-------+
   | host        | user  |
   +-------------+-------+
   | 192.168.0.3 | admin |
   +-------------+-------+
   1 row in set (0.00 sec)
   
   

5. 创建halo数据库

   mysql> create database halodb character set utf8mb4 collate utf8mb4_bin;
   Query OK, 1 row affected (0.01 sec)
   

Docker安装Halo

1. 下载halo配置样例，并对其进行修改

   [root@10-7-176-211 halo]# wget https://dl.halo.run/config/application-template.yaml -O ./application.yaml--2022-02-20 21:01:44--  https://dl.halo.run/config/application-template.yamlResolving dl.halo.run (dl.halo.run)... 104.21.22.75, 172.67.203.114, 2606:4700:3032::ac43:cb72, ...Connecting to dl.halo.run (dl.halo.run)|104.21.22.75|:443... connected.HTTP request sent, awaiting response... 200 OKLength: 798 [application/octet-stream]Saving to: ‘./application.yaml’./application.yaml                              100%[====================================================================================================>]     798  --.-KB/s    in 0s2022-02-20 21:01:46 (11.4 MB/s) - ‘./application.yaml’ saved [798/798]
   

   修改的内容包括:

   • 注释 H2 database configuration.部分
   • 启用 MySQL database configuration.部分
   • 修改 datasource 下的 url 中的 ip 地址部分为容器名称并修改密码为您设定的 MySQL 密码
   • 修改username为刚刚创建并授权了的admin用户和密码

   修改的内容:

   spring:  datasource:    driver-class-name: com.mysql.cj.jdbc.Driver    url: jdbc:mysql://some-mysql:3306/halodb?characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true    username: admin    password: my-secret-pw
   

2. 创建指定IP地址的halo容器

   [root@10-7-176-211 halo]# docker run -it -d --name halo -p 8091:8090 --ip 192.168.0.3 -v /opt/halo:/root/.halo --net halo-net --restart=unless-stopped halohub/halo
   

3. 查看halo容器是否正常启动

出现这两个图就说明服务器部署成功了！

解析域名并关闭开放的临时端口

绑定和解析域名，并把为看到效果而临时开放的端口8091关闭。

配置Nginx

1. nginx.conf添加如下配置

   server {        listen 80;        server_name www.xxxxx.com;        location / {                proxy_pass http://127.0.0.1:8091;        }   }   server {        listen 80;        server_name xxxxx.com;        location / {                proxy_pass http://127.0.0.1:8091;        }   }
   

2. 运行如下nginx命令，重新加载配置

   [root@10-7-176-211 nginx]# nginx -tnginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successful[root@10-7-176-211 nginx]# nginx -s reload
