【云原生之Docker实战】使用Docker部署Solo个人博客站点

一、卷首语

中秋之《乡愁》
临近中秋佳节，提前祝大家中秋快乐，阖家团圆！
在每个奋笔疾书的日子里，挥之不去的是那份乡愁！
这是我最喜欢的诗歌之一，是每个在外游子浓浓的思乡之情！

乡愁
席慕容
故乡的歌是一支清远的笛
总在有月亮的晚上响起
故乡的面貌 却是一种模糊的怅望
仿佛雾里的挥手别离
离别後
乡愁是一棵没有年轮的树
永不老去

三、检查本地docker环境

1.检查docker服务状态

[root@node ~]# systemctl status docker
● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
   Active: active (running) since Fri 2022-08-26 00:54:36 CST; 2 days ago

2.检查docker配置信息

[root@node ~]# docker info

WARNING: IPv4 forwarding is disabled

3.开启IPv4 forwarding

[root@node ~]# echo "net.ipv4.ip_forward=1" >>  /etc/sysctl.conf
[root@node ~]# systemctl restart network
[root@node ~]#  sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1

四、安装docker-compose

1.下载docker-compose二进制包

 curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

[root@node docker-compose]#  curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   423  100   423    0     0    362      0  0:00:01  0:00:01 --:--:--   362
100 16.2M  100 16.2M    0     0  8568k      0  0:00:01  0:00:01 --:--:-- 8568k

2.给文件增加执行权限

chmod +x /usr/local/bin/docker-compose 

3.检查docker-compose版本

[root@node docker-compose]# docker-compose version
docker-compose version 1.25.0, build 0a186604
docker-py version: 4.1.0
CPython version: 3.7.4
OpenSSL version: OpenSSL 1.1.0l  10 Sep 2019

五、下载solo镜像

[root@node ~]# docker pull   b3log/solo
Using default tag: latest
latest: Pulling from b3log/solo
e7c96db7181b: Pull complete 
f910a506b6cb: Pull complete 
c2274a1a0e27: Pull complete 
fb14f7edaadd: Pull complete 
4c5a70d63309: Pull complete

Digest: sha256:dc1a208824d0c90f5bc64d36d8e9635ea9355f23e45c9c1f6afe5a7c59fcf14f
Status: Downloaded newer image for b3log/solo:latest
docker.io/b3log/solo:latest

六、使用docker命令方式安装Solo

docker run --detach --name solo --network=host \
    --env RUNTIME_DB="MYSQL" \
    --env JDBC_USERNAME="root" \
    --env JDBC_PASSWORD="123456" \
    --env JDBC_DRIVER="com.mysql.cj.jdbc.Driver" \
    --env JDBC_URL="jdbc:mysql://127.0.0.1:3306/solo?useUnicode=yes&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true" \
    b3log/solo --listen_port=8080 --server_scheme=http --server_host=localhost --server_port=

七、使用docker-compose部署Solo

1.编辑docker-compose.yaml文件

[root@node solo]# cat docker-compose.yaml 
version: '3'
services:
   mysql:
        image: mysql:5.6
        restart: always
        ports:
          - 3232:3306
        environment:
           MYSQL_DATABASE: solo
           MYSQL_USER: solo
           MYSQL_PASSWORD: solo
           MYSQL_ROOT_PASSWORD: solo
        volumes:
           - /data/solo/mysql:/var/lib/mysql
        networks:
            - myweb-net
   solo:
        container_name: solo
        image:  b3log/solo
        restart: always
        ports:
          - 8078:8080
        environment:
          RUNTIME_DB: MYSQL
          JDBC_USERNAME: root
          JDBC_PASSWORD: solo
          JDBC_DRIVER: "com.mysql.cj.jdbc.Driver"
          JDBC_URL: "jdbc:mysql://192.168.3.166:3232/solo?useUnicode=yes&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true"
        networks:
          - myweb-net
        command: --listen_port=8080 --server_scheme=http 
#        volumes:
#          -  /data/solo/skins/:/opt/solo/skins/
            

volumes:
   wordpress:
   db:
networks:
   myweb-net:
        driver: bridge

2.创建Solo容器

[root@node solo]# docker-compose up -d
Creating network "solo_myweb-net" with driver "bridge"
Creating solo         ... done
Creating solo_mysql_1 ... done

3.查看Solo容器状态

[root@node solo]# docker ps
CONTAINER ID   IMAGE             COMMAND                  CREATED          STATUS          PORTS                                       NAMES
36d0bdc0a04e   mysql:5.6         "docker-entrypoint.s…"   19 minutes ago   Up 19 minutes   0.0.0.0:3232->3306/tcp, :::3232->3306/tcp   solo_mysql_1
e287abced896   b3log/solo        "java -cp lib/*:. or…"   19 minutes ago   Up 19 minutes   0.0.0.0:8078->8080/tcp, :::8078->8080/tcp   solo

4.查看Solo容器日志

[root@node solo]# docker logs solo |tail -n 5
[INFO ]-[2022-08-28 22:53:10]-[org.b3log.solo.Server:255]: Solo is booting [ver=4.3.1, os=Linux, isDocker=true, inJar=false, luteAvailable=false, pid=1, runtimeDatabase=MYSQL, runtimeMode=PRODUCTION, jdbc.username=root, jdbc.URL=jdbc:mysql://192.168.3.166:3232/solo?useUnicode=yes&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true]
