如果没有第二个磁盘，带有 raid1 文件系统的磁盘可以正常工作吗？

1

我买了一台主机，它有两个驱动器，每个驱动器 500GB。
但是这些磁盘是在 raid1 模式下使用的，结果我只有 500GB 可用。

但我想放弃 raid1 以换取更多空间。
我使用以下命令断开了第二个磁盘与 raid1 的连接：

mdadm --fail /dev/md0 /dev/nvme1n1p1
mdadm --remove /dev/md0 /dev/nvme1n1p1

之后，我在第二个磁盘上创建了我的 ext4 分区，我在主机上获得了 1000 GB。

现在细分看起来像这样lsblk：

NAME        MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
nvme0n1     259:0    0   477G  0 disk
├─nvme0n1p1 259:2    0    32G  0 part
│ └─md0       9:0    0    32G  0 raid1 [SWAP]
├─nvme0n1p2 259:3    0   512M  0 part
│ └─md1       9:1    0   511M  0 raid1 /boot
└─nvme0n1p3 259:4    0 444.4G  0 part
  └─md2       9:2    0 444.3G  0 raid1 /
nvme1n1     259:1    0   477G  0 disk
└─nvme1n1p1 259:5    0   477G  0 part  /mnt/tmp

如您所见，第一个磁盘的分区保留在带有raid1.

raid1问题：在没有第二个磁盘的文件系统中，第一个磁盘可以正常工作吗？

这是它显示的内容cat /proc/mdstat：

Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10]

是否可以隐藏传入连接的 IP 地址？

-1

我正在使用 debian 9。我有一个运行客户端连接的 java 服务器。我想让服务器无法找到客户端的真实 IP 地址。这是安全所必需的。

如果对于服务器来说，将客户端的 IP 地址替换为某个本地 IP，例如 127.0.0.1，那就太好了。

也许这可以使用 iptables 或内核设置来完成？

Bind9 不重定向 TCP 请求

我已经配置了绑定 dns 服务器。

这是他的配置和我的设置：

zone "lokha.local" {
    type forward;
    forward only;
    forwarders { 116.202.112.23; };
};

options {
        directory "/var/cache/bind";

        dnssec-validation no;

        auth-nxdomain no;    # conform to RFC1035
        listen-on-v6 { none; };
        listen-on port 57 { 127.0.0.1; };

        forwarders {
                8.8.8.8;
                8.8.4.4;
        };

        recursion yes;
        allow-transfer {"none";};
        allow-query { any; };
        allow-recursion { any; };
        forward first;
        querylog yes;
};

配置配置为将本地区域请求重定向lokha.local到我的 dns 服务器116.202.112.23。

我的 dns 服务器116.202.112.23只能响应 TCP dns 请求，因为 UDP 流量被防火墙阻止。

我用命令测试 dns 请求：

dig @127.0.0.1 +vc -p 57 host5.lokha.local

该参数+vc通过 TCP 发出请求。

但是 bind 仍然尝试通过 UDP 发出请求：

21:49:13.042919 IP (tos 0x0, ttl 64, id 10022, offset 0, flags [none], proto UDP (17), length 77)

如何强制bind9使用TCP？

是否可以覆盖繁忙的端口？

0

我有一个游戏服务器，它是一个 java 应用程序。此服务器侦听端口 25565。客户端连接到此服务器，连接可持续数小时。

我遇到了部署此服务器的新版本的问题。要运行新版本的服务器，必须关闭旧版本。但这会导致关闭与客户端的连接。即使在凌晨 4 点，也有不少顾客。

我想运行新版本的服务器，但只要有客户端连接就保持旧版本运行。但在这种情况下，新服务器将无法上线，因为它无法占用25565端口，该端口仍会被旧应用程序占用。

新服务器能否以某种方式覆盖端口 25565？
这样新的连接就会到达新的服务器，但与旧服务器的剩余连接不会关闭。

我的服务器正在运行 debian 9。

是否有可能找出一个主机的所有 IP 地址，只知道它的一个 IP 地址？

我的意思是可以在不访问主机的情况下获得这些信息。例如，通过 dns 请求或 icmp 请求。

如果重要的话，主机正在运行 Debian 9，主机在 ovh 上。

为什么 @Order 注释在春季不起作用？

我有一个春季项目：

│   ├── Bean1.java
│   ├── Bean2.java
│   ├── IBean.java
│   └── TestApplication.java

类Bean1和Bean2是 bean 并且都实现了接口IBean。在这些 bean 中，我创建了相同的 init 方法，它向控制台输出一条消息：

    @PostConstruct
    public void init() {
        System.out.println(this.getClass().getName());
    }

当我运行项目时，日志中会显示以下 bean 加载顺序：

ua.lokha.springtest.Bean1
ua.lokha.springtest.Bean2

我试图在@Order(1)and中放一个注释，我试图交换这个注释。而且它没有改变任何东西，总是在之前加载。为什么？@Order(2)Bean1Bean2Bean1Bean2

如何确保zabbix在交付规则Mounted filesystem discovery中没有检测到某些文件系统？

0

我的主机上有一个 /var/ftp 文件夹，它是 ftp 用户主目录的根目录。使用命令将其他目录安装到此文件夹mount --bind。该命令创建挂载点，zabbix 也将其视为文件系统。我想设置它以便它忽略它们。

我已经尝试自己找到解决方案。Mounted filesystem discovery我在选项卡中的传递规则中添加了以下过滤器Filters（字母 C 下列表中的第三个）：

在此过滤器中指定{#FSNAME}它不应匹配正则表达式^/var/ftp。我根据默认过滤器中的一个示例制作了这样一个正则表达式{$VFS.FS.FSNAME.NOT_MATCHES}，其值为^(/dev|/sys|/run|/proc|.+/shm$).

此下发规则的检测时间间隔为1h。我已经等了一个多小时，但多余的文件系统/var/ftp并没有消失，这些系统的数据还在继续更新。到我在 stackoverflow 上发帖时，已经过去了大约 3 个小时。

版本 zabbix-server 5.0.7。版本 zabbix-agent 5.0.7。

zabbix-server 和 zabbix-agent 在不同的主机上。

Java，AutoCloseable：资源是否应该释放父资源？

0

我现在给你举个例子。我有一个来自 hikaricp 库的数据库连接池：

HikariDataSource dataSource = new HikariDataSource(...);      
// работа с dataSource
dataSource.close();

在这种情况下dataSource，它是必须使用close.

但我不喜欢标准的jdbc，我为它做了一个包装：

HikariDataSource dataSource = new HikariDataSource(...);
JDBCWrapper jdbcWrapper = new JDBCWrapper(dataSource);
// работа с wrapper
wrapper.close();
dataSource.close();

该类JDBCWrapper是用于处理的包装器jdbc。但是在它内部创建了自己的资源，例如异步请求的线程池，所以这个包装器也是一个资源，并且有一个close释放它们的方法。

问题：包装器JDBCWrapper在调用其方法close时是否也应该释放dataSource？

一方面，dataSource它在wrapper里面，JDBCWrapper也应该被释放，另一方面，这个资源，从wrapper的角度来看，是“从外面”获得的，wrapper怎么知道，也许有人否则需要从外部获得此资源。

如果有的话，我不是在寻找数据库工具，我想解析这个特定的例子。

如何将 ovh 上的主 ipv4 更改为故障转移地址之一？

0

我有 ovh 主机 game1，debian 9 系统，它有一个主地址和 10 个故障转移地址。
我想将主地址更改为故障转移地址之一。
我需要这个，以便传出连接不使用主地址。

假设主地址是43.144.13.127，并且故障转移 -32.114.67.212

我目前的配置/etc/systemd/network/50-default.network是：

# This file sets the IP configuration of the primary (public) network device.
# You can also see this as "OSI Layer 3" config.
# It was created by the OVH installer, please be careful with modifications.
# Documentation: man systemd.network or https://www.freedesktop.org/software/systemd/man/systemd.network.html

# ... и остальные failover адреса

如何使地址32.114.67.212成为主要地址？也就是说，它用于传出连接？

我的逻辑是，因为我可以通过手动指定接口来发出传出请求，如下所示：

root@host:~# curl --interface failover ifconfig.me
32.114.67.212

那么一定有办法指定这个默认接口，但是怎么做呢？

为什么索引不用于排序？

1

我有一张桌子：

CREATE TABLE `player_statistics` (
    `id` INT(11) NOT NULL AUTO_INCREMENT,
    `player_id` INT(11) NOT NULL,
    `statistic_id` INT(11) NOT NULL,
    `value` INT(11) NOT NULL,
    PRIMARY KEY (`id`),
    INDEX `statistic_player_value` (`statistic_id`, `player_id`, `value`)
)

如您所见，有一个statistic_player_value包含 3 列的索引：statistic_id、player_id、value。

我用这个查询测试索引：

explain SELECT *
FROM `player_statistics` 
WHERE `statistic_id`=1 AND `player_id` =15
ORDER BY `value` desc
LIMIT 10;

结果：

+------+-------------+-------------------+------+-----------------------------------------------+------------------------+---------+-------------+------+--------------------------+
| id   | select_type | table             | type | possible_keys                                 | key                    | key_len | ref         | rows | Extra                    |
+------+-------------+-------------------+------+-----------------------------------------------+------------------------+---------+-------------+------+--------------------------+
|    1 | SIMPLE      | player_statistics | ref  | player_id,statistic_id,statistic_player_value | statistic_player_value | 8       | const,const |    1 | Using where; Using index |
+------+-------------+-------------------+------+-----------------------------------------------+------------------------+---------+-------------+------+--------------------------+

如您所见，它key_len等于 8，这意味着索引没有完全使用。player_id也只statistic_id使用了一个索引。我希望它key_len应该是12。

例如，此查询返回key_len12：

explain SELECT *
FROM `player_statistics` 
WHERE `statistic_id`=1 AND player_id =15 AND `value` = 1

那么问题是什么，为什么 order by 不使用索引呢？

git 如何决定在哪个方向绘制提交图？

1

假设在 branch1 分支中有一个提交，然后 branch2 分支从中分离出来，并在其中进行了 2 次提交。
Branch1 也有另一个提交。最后，将 branch2 分支合并到 branch1 中。

之后，branch1 和 branch2 分支被删除，经过多年的发展，所有的提交都在 master 中。

现在的问题是：git 如何准确地选择如何绘制这些提交的图表，正如我在上面描述的那样？
他有2个选项可供选择：

git如何选择如何绘制图形？他如何理解他commit 3正在创建一个新分支，而不是commit 5？

问题是，我正在编写一个程序来绘制一个 git 历史图。我知道有现成的程序，但我这样做是出于学习目的。

但我不想解析git log --graph. 我加载有关所有提交的所有数据并根据它们绘制图表。那些。我知道每个提交有哪些提交有祖先和提交子，但是我怎么知道哪些提交子恰好是新分支的创建，哪些是当前分支的延续？

即使一切正确，Java 内存转储也未完成

我有内存泄漏，服务器因内存不足错误而崩溃。

崩溃后的日志说：

#

# Native memory allocation (mmap) failed to map 1048576 bytes for committing reserved memory.
# Possible reasons:

#

日志说进行了内存转储：

Core dump written. Default location: /home/mcraft/servers/survival1/core or core.16671

但这不是真的，没有转储！
而且奇怪的是，这不是我在 VM Options 中指定的文件夹：

-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp/survival.hprof

磁盘上有足够的内存，有258G可用，我查看了df -H。
debian 9 系统，输出java -version：

为什么不进行转储？

我有一个服务器（不是网络），我在两个不同的主机上运行。

我希望列入白名单的 IP 请求发送到一个主机，而所有其他请求发送到另一台主机。

所有请求都从 nginx 转到共享 ip:port。

为什么 Hibernate 使用多个选择查询而不是仅一个查询来获取记录？

0

这是我的实体：

@Entity
public class ProductStateEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", nullable = false)
    private Integer id;

    @OneToOne
    @JoinColumn(name = "product_id", nullable = false)
    private ProductEntity product;

    // остальные поля
}


@Entity
public class ProductEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", nullable = false)
    private Integer id;

    // остальные поля
}

如果我提出这样的请求：

session.get(ProductStateEntity.class, 10);

SQL 是这样形成的：

SELECT product_states.id, product_states.product_id, products.id, -- остальные колонки
FROM product_states
INNER JOIN products ON product_states.product_id=products.id
WHERE product_states.id=10

到目前为止一切顺利，正在使用中INNER JOIN。

如果您提出这样的请求：

session.createQuery("from ProductStateEntity where id = :id")
            .setParameter("id", 10)
            .list()

SQL 是这样形成的：

SELECT product_states.id, product_states.product_id, -- остальные колонки
FROM product_states
WHERE product_states.id=10;

SELECT products.id, -- остальные колонки
FROM products
WHERE products.id=10

在这种情况下，发出了 2 个请求。首先，向 product_states 发出请求，然后向 products 发出请求。

这还不是全部，现在我们将发出这样一个请求，立即接收 4 个 id 的 4 条记录：

session.createQuery("from ProductStateEntity where id in :ids")
            .setParameter("ids", Arrays.asList(10, 11, 12, 13))
            .list();

SQL 是这样形成的：

SELECT product_states.id, product_states.product_id, -- остальные колонки
FROM product_states
WHERE product_states.id IN (10, 11, 12, 13);

SELECT products.id, -- остальные колонки
FROM products
WHERE products.id=10;

SELECT products.id, -- остальные колонки
FROM products
WHERE products.id=11;

SELECT products.id, -- остальные колонки
FROM products
WHERE products.id=12;

SELECT products.id, -- остальные колонки
FROM products
WHERE products.id=13;

在这种情况下，发出 5 个请求。首先对product_states进行请求，获取所有产品的id，然后分别进行1次请求，获取4个产品。

让我们添加join fetch到前面的查询：

session.createQuery("from ProductStateEntity p join fetch p.product where p.id in :ids")
            .setParameter("ids", Arrays.asList(10, 11, 12, 13))
            .list();

SQL 是这样形成的：

SELECT product_states.id, products.id, product_states.product_id, -- остальные колонки
FROM product_states
INNER JOIN products ON product_states.product_id=products.id
WHERE product_states.id IN (10, 11, 12, 13)

因此，仅使用 1 个请求INNER JOIN，这是我想要实现的。

所以问题：

为什么createQuery需要join fetch明确指定？是否可以将此行为设为默认行为？毕竟，一个带有连接的查询胜过很多。
为什么join fetch其他选择查询没有合并为一个 using id in (...)？相反，Hibernate 一次选择一个。这个可以定制吗？

我有一台主机vm1.yottacraft.ru（debian 9）运行带有 jmx 端口的 java 服务器20102。
我正在尝试使用 Windows 10 远程连接到此主机。

java应用程序的启动选项：

java \
    -Xms1G \

    -Dfile.encoding=UTF-8 \
    -Dcom.sun.management.jmxremote \

端口肯定是开的，我通过2ip.ru查看（可以自己查看，IP和端口更高）。

密码完全正确，文件权限也正确：

jmxremote.access- 644
