安装笔记：docker安装discuz
docker安装discuz
查询discuz镜像版本，选第一个
docker search discuz
下载镜像
docker pull docker.io/tencentci/discuz
启动discuz镜像，名称：BCB_BBS,外部 8000端口映射到内部 80端口
docker run --name BCB_BBS -d -p 8000:80 tencentci/discuz
访问主机地址8000端口，出现下面画面：
http://192.168.1.251:8000/
在宿主机上安装mariadb数据库
yum install mariadb-server
开启数据库服务
systemctl start mariadb
检查数据库的端口是3306，有这一端口，表明数据库已开启
ss -lntup | grep 3306
查看Mysql进程
ps -ef | grep mysql
运行数据库的初始化页面，如下图所示
mysql_secure_installation
详见
Mariadb数据库的安装与初始化

使用mysql -u指定用户，-p密码 登录mysql数据库
[root@localhost ~]# mysql -u root -p

创建名为：论坛的数据库
MariaDB [(none)]> create database BCB_BBS;
Query OK, 1 row affected (0.00 sec)
使用论坛数据库，查看里面是否有表
MariaDB [(none)]> use BCB_BBS
Database changed
MariaDB [BCB_BBS]> show tables

MariaDB [BCB_BBS]> exit
Bye
查看 BCB_BBS 这一容器的IP地址
[root@localhost ~]# docker exec BCB_BBS hostname -I
172.17.0.2
填写相关信息，创建论坛，如下图所示
打开http://192.168.1.251:8000/
我同意——取消（安装UTF8正式版下载）——
上图
这里数据库连接错误。先把centos的防火墙关闭：
systemctl stop firewalld
还提示错误：“Host ‘172.17.0.2’ is not allowed to connect to this MariaDB server”。这个问题应该是数据库root远程登录权限被禁止造成，如下操作：
mysql -u root -p #用root打开mysql
show databases; #显示已有数据库
use mysql #打开mysql库
select host, user from user; #列出主机、用户权限
grant all on *.* to root@'192.168.1.251' identified by 'mysql'; #给root用户在192.168.1.251上赋访问权限，密码 mysql
grant all on *.* to root@'%' identified by 'mysql'; #给root用户在任何主机上赋访问权限，密码 mysql
flush privileges; #更新
select host,user,password from user; #列出host，user，password权限列表
update user set user="root" where host='%'; #更新数据库用户权限
注意几点：
centos7防火墙必须关闭，论坛才能正常运行。
mariaDB安装完要赋予root用户，其他机器访问权限
让docker容器BCB_BBS开机自动启动
1、让docker服务自动开启
命令：systemctl enable 服务名称
[root@localhost ~]# systemctl enable docker 设置自动重启

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
You already have a root password set, so you can safely answer 'n'.
Change the root password? [Y/n] n
... skipping.
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n
... skipping.
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] n
... skipping.
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
