在树莓派3上搭建Mattermost
我想在Raspberry Pi 3上搭建Mattermost。
只需一种选项：
参考的网站
在RaspberryPi3上安装Mattermost的步骤：

MariaDB的配置
安装MariaDB
因为这个已经安装过了，所以略过。
尝试安装MySQL时，被替换为了MariaDB。
基本上以为是MySQL并进行了操作没有问题。
MariaDB的配置
请提供根密码。
应该在MariaDB创建时设置的。
$ sudo mysql -u root -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 44
Server version: 10.3.22-MariaDB-0+deb10u1 Raspbian 10
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]>
我将创建一个名为mmuser的用户。
密码将由用户自行设置。
我将确认用户是否能正确创建。
MariaDB [(none)]> create user 'mmuser'@'%' identified by ‘your-password‘
-> ;
Query OK, 0 rows affected (0.081 sec)
MariaDB [(none)]>
MariaDB [(none)]> select user,host from mysql.user;
+--------+-----------+
| user | host |
+--------+-----------+
| mmuser | % |
| root | localhost |
+--------+-----------+
2 rows in set (0.006 sec)
MariaDB [(none)]>
创建一个名为Mattermost的数据库，并进行其他设置。
完成后，使用exit命令从MariaDB注销。
MariaDB [(none)]> create database mattermost;
Query OK, 1 row affected (0.005 sec)
MariaDB [(none)]>
MariaDB [(none)]> grant all privileges on mattermost.* to 'mmuser'@'%';
Query OK, 0 rows affected (0.005 sec)
MariaDB [(none)]>
MariaDB [(none)]> GRANT ALTER, CREATE, DELETE, DROP, INDEX, INSERT, SELECT, UPDATE ON mattermost.* TO 'mmuser'@'%';
Query OK, 0 rows affected (0.008 sec)
MariaDB [(none)]>
MariaDB [(none)]> exit
引入Mattermost
如果您想在Raspberry Pi 3上安装Mattermost，由于官方没有提供支持，所以无法安装。原因是因为Raspberry Pi 3不支持64位系统。
$ getconf LONG_BIT
32
因此，从以下支持32位的网站上下载。

一旦使用wget工具下载完成后，我们将对其进行解压操作。
$ tar -xvzf mattermost*.gz

mattermost/bin/
mattermost/bin/platform
mattermost/logs/
mattermost/config/
〜長いので省略〜

mattermost/client/root.html
mattermost/MIT-COMPILED-LICENSE.md
mattermost/NOTICE.txt
mattermost/README.md
一旦解冻成功后，我们将继续进行剩余的设置工作。
$ sudo mv mattermost /opt
$ sudo mkdir /opt/mattermost/data
$ sudo useradd --system --user-group mattermost
$ sudo chown -R mattermost:mattermost /opt/mattermost
$ sudo chmod -R g+w /opt/mattermost
我会修改json文件的内容。
我会修改SqlSettings的DataSource。
这是修改后的内容。
$ sudo vi /opt/mattermost/config/config.json
“DataSource”: “mmuser:your-password@tcp(localhost:3306)/mattermost?charset=utf8mb4,utf8¥u0026readTimeout=30s¥u0026writeTimeout=30s”,
会启动 Mattermost。启动可能需要一点时间。
$ cd /opt/mattermost
$ sudo -u mattermost ./bin/platform

如果站起来后，在Raspberry Pi 3的浏览器中访问 http://localhost:8065 ，将会打开Mattermost的界面。
从另一台电脑上，也可以通过访问 http://树莓派3的IP地址:8065 来打开。
个人的困难点
- 我不知道从Mattermost公式网站下载的资源是64位的，因此无法运行。我在修改json文件时失败了。因为设置了dockerhost的查看配置，直到我注意到那里的错误才花了一些时间。
