我有一台装有 Ubuntu 20.04 LTS 和 MySQL 8 的服务器

我的系统驱动器通常在 20gb 可用的 11gb 左右。

一个星期以来，我的数据库已经使用了所有东西。

为什么 MySQL 占用了我服务器上的所有空间？

为什么数据库从 1.4gb 变成 14gb

ubuntu@ov-376Gf2 ~ $ sudo du -h -d 1 /var/lib/mysql
1.5M    /var/lib/mysql/performance_schema
84K /var/lib/mysql/sys
622M    /var/lib/mysql/www_s1biose_com
164K    /var/lib/mysql/#innodb_temp
36K /var/lib/mysql/mysql
14G /var/lib/mysql

我有一台 Ubuntu 20.04 的服务器，问题是disk/dev/vda1分区已满。但是，我几乎没有要安装的东西。

你怎么知道哪个文件或目录占用了所有空间？

我正在尝试使用下面的命令行备份我的 MySQL 8 数据库，但我收到一条错误消息。

如何进行备份？

ubuntu@www-example-com ~ $ mysqldump -u root -p www_example_com > /var/www/www-example-com/share/www-example-com_$(date +%F).sql

-bash: /var/www/www-example-com/share/www-example-com_$(date +%F).sql: Permission denied

我有一台带有 ubuntu 20.04 的服务器

但我无法nginx-module-brotli为我的 nginx 服务器安装。

以下是我用来为 Nginx 安装 Brotli 的命令：

$ sudo apt install git gcc cmake libpcre3 libpcre3-dev zlib1g zlib1g-dev openssl libssl-dev
$ wget https://nginx.org/download/nginx-1.18.0.tar.gz
$ tar zxvf nginx-1.18.0.tar.gz
$ git clone https://github.com/google/ngx_brotli.git
$ cd ~/ngx_brotli
$ git submodule update --init
$ cd ~/nginx-1.18.0
$ ./configure --with-compat --add-dynamic-module=../ngx_brotli
$ make modules
$ sudo cp ./objs/*.so /usr/share/nginx/modules
$ cd

和

$ sudo nano /etc/nginx/nginx.conf

load_module modules/ngx_http_brotli_filter_module.so;
load_module modules/ngx_http_brotli_static_module.so;

ubuntu@ov-ert6:~$ sudo systemctl restart nginx

ubuntu@ov-ert6:~$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

当我测试我的网站时，它在标题中找不到 Brotli：

我有一个 Ubuntu 20.04 服务器，我按照本教程安装 ProtonMail Bridge：

https://pychao.com/2020/06/10/update-on-using-protonmail-bridge-on-headless-wordpress-linux-servers/

ProtonMail 用户需要这个额外实用程序的原因是，对于出站电子邮件，ProtonMail 在将电子邮件移交给发送服务器之前对用户的电子邮件内容进行加密。而对于入站邮件，ProtonMail 在下载邮件后为用户解密邮件内容，因此当用户打开收到的邮件时，内容是可读的。在使用 ProtonMail 的在线界面时，一切都在幕后完成。用户只需像在 Gmail 上一样编写/阅读电子邮件等。但是如果用户想在本地计算机上使用离线电子邮件客户端，那么这些客户端在与 ProtonMail 的服务器进行通信之前/之后缺乏加密/解密电子邮件的功能（请参阅注1）。这就是 ProtonMail 提供名为 Bridge 的实用程序的原因。

简而言之，ProtonMail Bridge 在本地机器上创建了虚假的 IMAP/SMTP 服务器。并且用户在他们的离线电子邮件客户端中使用这些虚假的本地服务器进行 IMAP/SMTP 设置。当离线客户端尝试与电子邮件服务器进行通信时，他们实际上是在与虚假的本地服务器进行通信。接下来，本地服务器执行加密/解密任务，然后与真正的 ProtonMail 服务器通信。

欲知更多详情，请阅读 ProtonMai Bridge 的介绍。这篇文章不打算处理 Bridge 的使用。相反，这篇文章试图解决在无头（即，未连接到任何物理监视器）Linux 环境中使用 Bridge 时出现的问题。

我的服务器上有一个 Drupal 8 站点，它使用 ProtonMail Bridge 正确发送电子邮件。

现在我希望 Postfix 使用 ProtonMail Bridge 发送服务器电子邮件（Logwatch，Monit，...）。

我按照以下教程安装和配置 Postfix ：

https://devanswers.co/configure-postfix-to-use-gmail-smtp-on-ubuntu-16-04-digitalocean-droplet/

这是我的配置

安装后缀

$ sudo apt install postfix

在“系统邮件名称”处输入域 mydomain.com，其余部分默认保留

配置后缀

$ sudo nano /etc/postfix/main.cf

...

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = ov-hjhjhjhj.kjkjkjj.ch
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = $myhostname, mydomaine.com, ov-b2bbd0.infomaniak.ch, localhost.infomaniak.ch, localhost
relayhost = [127.0.0.1]:1025
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = loopback-only
inet_protocols = all

创建 sasl_passwd 文件以存储凭据

$ sudo nano /etc/postfix/sasl_passwd

...

[127.0.0.1]:1025 [email protected]:password

ProtonMail Bridge 中的使用信息

创建哈希数据库文件

$ sudo postmap /etc/postfix/sasl_passwd

安全凭证

$ sudo chown root:root /etc/postfix/sasl_passwd /etc/postfix/sasl_passwd.db
$ sudo chmod 0600 /etc/postfix/sasl_passwd /etc/postfix/sasl_passwd.db

重启后缀

$ sudo systemctl restart postfix

检查状态后缀

$ sudo systemctl status postfix

安装 mailutils

$ sudo apt install mailutils

测试发送电子邮件

$ echo "Contenu du mail" | mail -s "Titre du mail" [email protected] -aFrom:[email protected]

问题是我没有收到任何电子邮件，也没有错误消息。我的设置有什么问题？

这是有效的 Drupal 8 配置：

我有一个 Ubuntu 20.04 的 Solr 服务器

我遵循了文档，但我无法更改默认密码。

我怎样才能做到这一点 ？
