用于安装网站的 Bash 脚本

首先，如果这是一个错误的地方问这个问题，请原谅。

我制作了一个 Bash 脚本，将 DirectAdmin 备份安装到 Apache 中。这些步骤有效，但最终我在打开实际网站时收到 500 错误。

步骤：
1. 解压 backup.tar.gz
2. 删除 unessecary 文件
3. 询问网站名称中的数据库详细信息
4. Cat 到 admin.conf 文件
5. 创建数据库和用户
6. 创建并 cat 到/etc/apache2/sites-available/website.conf
7.a2ensite和service apache2 reload
8. 创建Windows 主机文件中的条目

我已经追踪了所有步骤，似乎一切正常，但是当我输入 URL 时，出现 500 错误。这一切都在没有脚本的情况下完成，一切正常。

有人能告诉我错误可能来自哪里吗？使用 bash 脚本执行所有这些步骤时有什么不同吗？

编辑：这是使用的整个脚本：

#!/bin/bash
clear
tar -zxvf backup.tar.gz
sudo cp -R ./domains/*/public_html/* ./
sudo cp ./backup/*.sql ./
rm -rf ./backup ./domains
rm backup.tar.gz
sudo chmod 775 ./config.php

当我通过 DirectAdmin 从网站 www.example.com 进行备份并在脚本中使用该网站时，一切都按预期进行，但在浏览器中输入 URL 时，出现 500 错误。

Apache 日志为空。

哦，你需要使用ip_conntrack，请执行以下步骤：

  1. modprobe ip_conntrack

  2. sysctl获取with的变量列表sysctl -a |grep -i conn：
    输出为“：

    net.netfilter.nf_conntrack_acct = 0
net.netfilter.nf_conntrack_buckets = 65536
net.netfilter.nf_conntrack_checksum = 1
net.netfilter.nf_conntrack_count = 116
net.netfilter.nf_conntrack_events = 1
net.netfilter.nf_conntrack_expect_max = 1024
net.netfilter.nf_conntrack_generic_timeout = 600
net.netfilter.nf_conntrack_helper = 0
net.netfilter.nf_conntrack_icmp_timeout = 30
net.netfilter.nf_conntrack_log_invalid = 0
net.netfilter.nf_conntrack_max = 262144
net.netfilter.nf_conntrack_tcp_be_liberal = 0
net.netfilter.nf_conntrack_tcp_loose = 1
net.netfilter.nf_conntrack_tcp_max_retrans = 3
net.netfilter.nf_conntrack_tcp_timeout_close = 10
net.netfilter.nf_conntrack_tcp_timeout_close_wait = 60
net.netfilter.nf_conntrack_tcp_timeout_established = 432000
net.netfilter.nf_conntrack_tcp_timeout_fin_wait = 120
net.netfilter.nf_conntrack_tcp_timeout_last_ack = 30
net.netfilter.nf_conntrack_tcp_timeout_max_retrans = 300
net.netfilter.nf_conntrack_tcp_timeout_syn_recv = 60
net.netfilter.nf_conntrack_tcp_timeout_syn_sent = 120
net.netfilter.nf_conntrack_tcp_timeout_time_wait = 120
net.netfilter.nf_conntrack_tcp_timeout_unacknowledged = 300
net.netfilter.nf_conntrack_timestamp = 0
net.netfilter.nf_conntrack_udp_timeout = 30
net.netfilter.nf_conntrack_udp_timeout_stream = 180
net.nf_conntrack_max = 262144

  3. 改变net.ipv4.netfilter.ip_conntrack_max 变量。

  4. 存储在文件中。
