在 CentOS 6 上，我正在尝试按照https://www.mysterydata.com/how-to-install-upgrade-to-php-7-4-on-上的说明将我的 PHP 从 5.3 更新到 7.x rhel-centos-vestacp/。

当我做最后一步时：
yum install php php-opcache php-gd php-curl php-mysqlnd

我得到错误：

Error: Package: php-pecl-ncurses-1.0.1-1.el6.x86_64 (@epel)
           Requires: php(api) = 20090626

有没有办法解决这个问题？

我需要测试刚刚添加到我的 java 应用程序中的 SMTP 电子邮件发送功能。到目前为止，我只使用我的私人 Gmail 帐户对其进行了测试。它工作正常。

现在我想测试各种设置：SSL、无 SSL、TLS、无 TLS、更改端口、需要身份验证或不进行身份验证等。这是因为这个应用程序很快就会面向客户，我认为他们都有不同的 SMTP 设置. 我想确保该应用程序在大多数情况下都能正常工作。

我应该如何测试我的应用程序电子邮件发送功能？

我应该在我的本地 Windows 7 机器上设置一些 SMTP 服务器吗？

走哪条路？

我刚刚清理了我被黑的 CentOS 服务器（由于自 versino 5.3 以来没有更新）。但是，“chkrootkit”仍然这样说：

/usr/lib/python2.4/distutils/.relocation-tag

会不会是“chkrootkit”不喜欢.hmac、.packlist 和.relocation-tag 文件？

这些真的还感染吗？

可能重复：
我的服务器被黑了紧急情况

我的 Linux 机器最近被黑了。

/etc/inittab 下面有几个完整的

#end of /etc/inittab

就像是：

#Loading standard ttys
0:2345:once:/usr/sbin/ttyload

我还有以下几行：

2:2345:respawn:/sbin/mingetty tty2
3:2345:respawn:/sbin/mingetty tty3
.
.
.

我知道我/usr/sbin/ttyload的被黑了，我已经去掉了，但是我不知道我是否需要这个是inittab，也不知道我之前有没有ttyload。这个文件通用吗？

我应该删除这一行吗？

/lib/libsh.so这个文件属于哪个包？

我需要更换它，因为它被感染了。/etc/sh.conf 也一样。

现在，我已将其移至 /temp/libsh.so.infected。我可以删除它吗？

编辑 1：

我刚刚发现 libsh.so 不是一个文件，而是一个包含以下文件的目录： bash shdcf shhk shhk.pub shrs

我的服务器被黑了紧急情况

我正在运行 CentOS 5.3，这是“chkrootkit”的结果：

Possible t0rn v8 \(or variation\) rootkit installed

Warning: Possible Showtee Rootkit installed
 /usr/include/file.h /usr/include/proc.h
Warning: `//root/.mysql_history' file size is zero

! root         3043 tty5   /sbin/mingetty tty5
! root         3046 tty6   /sbin/mingetty tty6

我不明白警告是什么意思。

服务器是否被感染或处于危险之中？

编辑：

让我补充一下，我首先在命令行上收到了奇怪的消息：

Unknown HZ value! (##) Assume 100

然后我按照这个很好的说明，用新文件替换了我被黑的文件。我更换了：

/sbin/ifconfig
/bin/netstat
/usr/bin/pstree
/usr/bin/top

他们都被报告为感染了“chkrootkit”。

现在我重新运行“chkrootkit”并得到上面的输出。如何继续摆脱所有警告？

大约 3 年前，我们的小公司租了一台远程机器。该机器用作公司服务器，运行我们的电子邮件、网络、源代码存储库、bugtracker、论坛、wiki 等。

操作系统是linux CentOS 5.3，带有Plesk 9.5 控制面板。我觉得两个都太老了。

将 CentOS 更新到当前版本有多复杂？在这种情况下，Plesk 会发生什么情况？应该先更新 Plesk 吗？还是应该继续使用 CentOS 5.3？

我对新的 Rsnapshot 配置感到困惑。在当前版本中，有一种不同的方式来指定备份间隔，如下所示：

retain hourly  2
retain weekly  7
retain monthly 2

我想每月进行几次手动备份。我想保存 3 个档案。我应该如何设置上面的代码？

我有一台远程 Linux 服务器机器，我想时不时地对其进行镜像备份。由于我是 Windows 用户，我在 Windows 上安装了 Linux 虚拟机，现在我使用 rsnapshot 进行备份。因此，rsnapshot 从远程 linux 服务器获取数据并将它们备份到本地 linux 虚拟机中。

虚拟机中的这种备份安全且好吗？

我是否应该在不同的驱动器上正常安装 Linux 并在那里使用双引导和备份？
