docker 部署 solo 失败的问题

部署在 Linux 虚拟机上,版本是 Ubuntu server18.04
前序步骤都搞定之后,在启动 solo 容器时出现错误
启动命令

docker run -h --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" \
    b3log/solo --listen_port=8080 --server_scheme=http --server_host=localhost --server_port=

请问这里 Address in use 的报错原因是?
