Nginx
1 前言
一个问题，一篇文章，一出故事。
最近由于需要发布维护公告，想着这种东西以后用得着，于是总结本章。
2 最佳实践
2.1 创建维护页面
vim /var/www/nextcloud.cmdschool.org/maintenance.html
创建如下代码，
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Maintenance Notice - Nextcloud</title>
<style>
body {
font-family: Arial, sans-serif;
text-align: center;
margin: 50px;
}
h1 {
color: #333;
}
p {
color: #666;
}
</style>
</head>
<body>
<h1 id="maintenance-title"></h1>
<p id="maintenance-message"></p>
<script>
var lang = navigator.language || navigator.userLanguage;
var title, message;
if (lang.startsWith('zh')) {
title = '维护通知';
message = '我们正在进行系统维护，暂时无法访问 Nextcloud。请稍后再试。感谢您的理解和耐心。';
} else {
title = 'Maintenance Notice';
message = 'We are currently undergoing system maintenance and Nextcloud is temporarily unavailable. Please try again later. Thank you for your understanding and patience.';
}
document.getElementById('maintenance-title').textContent = title;
document.getElementById('maintenance-message').textContent = message;
</script>
</body>
</html>
2.2 设置Nginx访问维护页面
vim /etc/nginx/conf.d/nextcloud.cmdschool.org_443_nextcloud.conf
创建如下代码，
server {
location / {
return 503;
#...
}
error_page 503 @maintenance;
location @maintenance {
root /var/www/nextcloud.cmdschool.org;
rewrite ^(.*)$ /maintenance.html break;
}
location = /maintenance.html {
root /var/www/nextcloud.cmdschool.org;
}
}
设置后，你需要重载服务使配置生效
nginx -t systemctl reload nginx
