solo_Tomcat 转 docker 并升级 (问题好多!)

本贴最后更新于 1985 天前，其中的信息可能已经时移世改

序

      之前 solo 一直老老实实地运行 Tomcat 上，上个月有功夫升级，从 v3.6.1 升级到 v3.6.2 但失败了，因没有时间之前也没来得及查找原因，最近想进行升级，又突然想试试用 docker 来运行，故开始折腾了……

一、Docker 安装(CentOS7)

      安装一些必要的系统工具：

          sudo yum install -y yum-utils device-mapper-persistent-data lvm2

      添加软件源信息：

          sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

      更新 yum 缓存：

          sudo yum makecache fast

      安装 Docker-ce：

          sudo yum -y install docker-ce

      启动 Docker 后台服务

          sudo systemctl start docker

      完成之后可以测试一下 docker 是否安装成功

二、停止运行 Tomcat

      Tomcat 路径下 /bin 目录下执行

          ./shutdown.sh

      目前 Tomcat 端口号为 8080

三、Docker 部署 solo

      按照官方文档来说，docker 部署安装 solo 很简单。

1）获取最新镜像

          docker pull b3log/solo

2）安装 Mysql？

               原先已在 docker 容器外部进行了 Mysql 部署安装，现在只需要用即可

3）启动容器

      下面具体参数含义，详见官方文档

          docker run  --name solo \
	  --network=host --env RUNTIME_DB="MYSQL"  \
	  --env JDBC_USERNAME="root" \
	  --env JDBC_PASSWORD="XXX"  \
	  --env JDBC_DRIVER="com.mysql.cj.jdbc.Driver" \
	  --env JDBC_URL="jdbc:mysql://localhost:3306/solo?useUnicode=yes&characterEncoding=UTF-8&useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC" \
	  b3log/solo --listen_port=8080 --server_scheme=https --server_host=aeneag.xyz --server_port=80

4）报错来了

5）解决报错

      读报错内容，你会发现 commentContent 这个地方有错，在 github 上发现有一个同样的错误，并和 D 哥交流，得知是数据库中有些表的字段字符集和排序规则不对，可能是之前升级没进行修复。
      b3_solo_comment 表中的 commentContent 字段，b3_solo_article 表中的 articleAbstract、articleContent、articleAbstractText 这三个字段，字符集改为 utf8mb4，排序规则用 utf8mb4_general_ci。
      这样该错误就会解决，同时想到了之前 Tomcat 上 solo v3.6.1 升级 v3.6.2 失败的原因，应该也是这个问题，之前 Tomcat 上升级造成的后果便是 Tomcat 直接运行失败，报 jar 包的错，也懒的管，直接退回 v3.6.1

6）执行第 3 步，启动容器

      执行第三步之前，请把之前的 solo 删除，再执行第 3 步

          docker rm solo

      这样容器启动成功，输入网址即可(之前 Nginx 配置 8080，又 docker 设置 8080，故无需更改输入网址即可打开 solo)

7）皮肤配置

      下面这条命令可以在第 3 步的命令中加上，使用 docker 挂载目录命令，一定要弄明白前后的路径代表什么含义，前面代表寄宿机的路径，后面代表容器虚拟路径。因先入为主的原因一直认为后面代表寄宿机路径，搞了好久…… 这样就可以改皮肤了

          --volume /opt/solo/skins/:/opt/solo/skins/

四、启动 Tomcat

      因 Tomcat 上有另一个小项目，Tomcat 仍需运行

1)删除 solo 项目

      Tomcat webapps 目录下的 solo-v3.6.1 项目文件

2)修改配置

      修改 Tomcat 配置文件，修改 conf 目录下 server.xml 文件，更改 Tomcat 端口号，8080-->8888，删除配置 solo 的节点，修改完毕

3)启动 Tomcat

          ./startup.sh  //bin目录下

五、修改 Nginx 配置

      修改主要目的是 Tomcat 和 docker 同时都可以用域名访问
      Nginx 原先配置如下：

    upstream myblog{
        server localhost:8080;
    }    
    server {
        listen       80;
        server_name  aeneag.xyz www.aeneag.xyz;
        rewrite ^/(.*)$ https://aeneag.xyz/$1 permanent;
    }
    server {
        listen 443  ssl;
        server_name aeneag.xyz www.aeneag.xyz;
        root html;
        index index.html index.htm;
        ssl_certificate  ../cert/aeneag.xyz.pem;
        ssl_certificate_key ../cert/aeneag.xyz.key;
        ssl_session_timeout 5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;
        location / {
              root html;
              index index.html index.htm;
              proxy_pass http://myblog$request_uri;
              proxy_set_header  Host $host:$server_port;
              proxy_set_header  X-Real-IP  $remote_addr;
              client_max_body_size  10m;
        }
    }

      现在修改为：

    upstream myblog{
        server localhost:8080;
    }    
    upstream myperson{
        server localhost:8888;
    }
    server {
        listen       80;
        server_name  aeneag.xyz;
        rewrite ^/(.*)$ https://aeneag.xyz/$1 permanent;
    }
    server {
        listen       80;
        server_name  www.aeneag.xyz;
        rewrite ^/(.*)$ https://www.aeneag.xyz/$1 permanent;
    }
    server {
        listen 443  ssl;
        server_name aeneag.xyz;
        root html;
        index index.html index.htm;
        ssl_certificate  ../cert/aeneag.xyz.pem;
        ssl_certificate_key ../cert/aeneag.xyz.key;
        ssl_session_timeout 5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;
        location / {
              root html;
              index index.html index.htm;
              proxy_pass http://myblog$request_uri;
              proxy_set_header  Host $host:$server_port;
              proxy_set_header  X-Real-IP  $remote_addr;
              client_max_body_size  10m;
        }
    }
    server {
        listen 443  ssl;
        server_name www.aeneag.xyz;
        root html;
        index index.html index.htm;
        ssl_certificate  ../cert/aeneag.xyz.pem;
        ssl_certificate_key ../cert/aeneag.xyz.key;
        ssl_session_timeout 5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;
        location / {
              root html;
              index index.html index.htm;
              proxy_pass http://myperson$request_uri;
              proxy_set_header  Host $host:$server_port;
              proxy_set_header  X-Real-IP  $remote_addr;
              client_max_body_size  10m;
        }
    }

六、尾

      至此，soloTomcat 转 Docker 并升级，还能同时运行已全部完成，花的不少时间，最耗时的就是解决错误，太费时间了 😰

  • Docker

    Docker 是一个开源的应用容器引擎，让开发者可以打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的操作系统上。容器完全使用沙箱机制，几乎没有性能开销，可以很容易地在机器和数据中心中运行。
