> 系统版本：openEuler 24.03 (LTS-SP1) aarch64

>  前提 
 在安装流程编译完zlmediakit 之后运行 .\MediaServer.exe -d 
 提示 Segmentation fault（核心已转储） 提示 Segmentation fault（核心已转储）

后面开始排查：
#### 1. 开启 core dump
    ulimit -c unlimited

#### 2. 查看 core 生成方式
    cat /proc/sys/kernel/core_pattern

#### 3. 前台运行看日志
    ./MediaServer

#### 4. 若有 core 文件
     gdb ./MediaServer core

#### 5. 若用 systemd-coredump
    coredumpctl list
    coredumpctl debug ./MediaServer

###交给模型分析

### 初步判断是：
 
> ZLMediaKit 静态链接了 jemalloc，但与 openEuler 24.03 的 glibc 或内核存在兼容性问题
ZLMediaKit 默认会 内置编译并链接自己的 jemalloc（位于 3rdpart/jemalloc 子模块）
而 openEuler 24.03 使用较新的 glibc 2.38 + 内核 6.x，对内存布局、ASLR、指针加密（PAC）等有更严格要求
旧版 jemalloc（尤其是 ZLMediaKit 自带的版本）在 aarch64 + 新系统上可能因指针对齐、原子操作或虚拟地址假设错误而崩溃

#### 解决方法：
> 修改 CMakeLists.txt 强制跳过 jemalloc
编辑 /ZLMediaKit/CMakeLists.txt，找到类似这段代码

```shell
find_library(JEMALLOC_LIBRARIES NAMES jemalloc)
if(JEMALLOC_LIBRARIES)
    message(STATUS "found library: ${JEMALLOC_LIBRARIES}")
    message(STATUS "jemalloc will be used to avoid memory fragmentation")
    target_link_libraries(${PROJECT_NAME} PRIVATE ${JEMALLOC_LIBRARIES})
endif()
```

#### 注释掉或删除整个 if(JEMALLOC_LIBRARIES) 块：

```shell
# find_library(JEMALLOC_LIBRARIES NAMES jemalloc)
# if(JEMALLOC_LIBRARIES)
#     message(STATUS "found library: ${JEMALLOC_LIBRARIES}")
#     message(STATUS "jemalloc will be used to avoid memory fragmentation")
#     target_link_libraries(${PROJECT_NAME} PRIVATE ${JEMALLOC_LIBRARIES})
# endif()
```

#### 然后重新 cmake + make。

重新编译之后可正常运行。

1.修改php.ini 添加配置
```php

[PHP_DM]
extension =libphp80_dm
extension = php80_pdo_dm

[dm]
dm.port=5237
; ; 是否允许持久性连接
 dm.allow_persistent = 1
; ; 允许建立持久性连接的最大数. -1 为没有限制.
 dm.max_persistent = -1
; ; 允许建立连接的最大数(包括持久性连接). -1 为没有限制.
 dm.max_links = -1
; ; 默认的主机地址
 dm.default_host = 0.0.0.
; ; 默认登录的数据库
 dm.default_db = SYSTEM
; ; 默认的连接用户名
 dm.default_user = SLT
; ; 默认的连接口令.
 dm.default_pw = 00000
; ;连接超时，这个参数未实际的用到，等待服务器支持
 dm.connect_timeout = 10
; ;对于各种变长数据类型，每列最大读取的字节数。如果它设置为 0 或是小于 0,那么，读取变长字段时，将显示 NULL 值
 dm.defaultlrl = 4096
; ; 是否读取二进制类型数据，如果它设置为 0，那么二进制将被 NULL 值代替
 dm.defaultbinmode = 1
; ;是否允许检察持久性连接的有效性，如果设置为 ON，那么当重用一个持久性连接时，会检察该连接是否还有效
 dm.check_persistent = ON
```

在web服务器中（/home/dmdbms/bin 是已经拷贝到从数据库服务器中拷贝到web服务器中的文件夹）
```shell

source ~/.bashrc
```

1.PHP message: PHP Fatal error: Unable to start DM module in Unknown on line 0
 
【问题解决】
达梦数据库安装的目录 bin 文件夹下的 libdmdpi.so 文件放入 /usr/lib 或者 /usr/lib64/ 目录里即可解决。(我是放在lib64目录之后才不报错的)

CentOS 8安装 KVM+Cockpit

作者: HAS

最小安装镜像源：
```
https://mirrors.aliyun.com/centos/8/BaseOS/aarch64/os
```

CentOS 8 系统软件源（dnf/yum）

# 备份原 repo

```shell
sudo mkdir -p /etc/yum.repos.d/backup
sudo mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup/
```

# 下载阿里云 CentOS-Vault.repo

```shell
sudo curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
```

# 清理并生成缓存
```shell
sudo dnf clean all
sudo dnf makecache
```

## 1，安装 Cockpit
1. 安装kvm
	```shell
yum install qemu-kvm libvirt libvirt-daemon virt-install virt-manager libvirt-dbus
systemctl start libvirtd.service
```

* 注意：如果访问虚拟机，点击虚拟机Create VM按钮是灰色的，就表示没有安装virt-install包
 
2. 首先执行如下命令安装 Cockpit：
```shell
dnf install cockpit cockpit-machines
```
2.安装完毕后执行如下命令启动 Cockpit 服务并设置为自动启动：

```shell
systemctl start cockpit.socket
systemctl enable cockpit.socket
```

3.接着执行如下命令查看是否启动成功：

```shell
systemctl status cockpit.socket
```

4.由于 Cockpit 默认使用的是 9090 端口，执行如下命令打开这个端口：

```shell
firewall-cmd --permanent --add-port=9090/tcp
firewall-cmd --reload 
```

另外：
### 1.创建网桥
 
#### 在网络中点击添加网桥，设置名称br0，选择ens192上网的端口，最后点击确定就创建成功了

### 2、修改默认kvm存储池
注意：kvm存储池默认存放在/var/lib/libvirt/images，也就是说，你所创建的虚拟机会生成在该目录下，建议挂载大磁盘空间，单独存放。

修改kvm存储池方法有很多种，我这里使用ln软连接来实现，我这里将libvirt整个目录软链存放在/data/kvm下。

```shell
mkdir -p /data/kvm
mv /var/lib/libvirt /data/kvm/
ln -sv /data/kvm/libvirt /var/lib/libvirt
```

独创建个目录用于存放ISO镜像包。
```shell
mkdir -p /data/iso
```
> ！！！！ 如果虚拟机不能启动需要 将 SELinux 设为宽容模式

```shell
sudo setenforce 0
```

### 3、磁盘扩容
virsh domblklist <虚拟机名称>
使用 qemu-img 扩容磁盘（以 qcow2 为例）

#### 检查当前大小（可选）
```shell
qemu-img info /var/lib/libvirt/images/centos-stream8_1.qcow2
```

#### 扩容到 30GB
```shell
sudo qemu-img resize /var/lib/libvirt/images/centos-stream8_1.qcow2 +20G
```
#### 或直接指定总大小：
 ```shell
sudo qemu-img resize /var/lib/libvirt/images/centos-stream8_1.qcow2 30G
```

GBase 8s PHP8

1.安装完数据库之后需要安装 CSDK
	解压 clientsdk_3.5.1_3X1.tar 然后执行
 `[root@localhost csdk]# ./installclientsdk -i silent  -DUSER_INSTALL_DIR=/opt/gbase -DLICENSE_ACCEPTED=TRUE
`
 DUSER_INSTALL_DIR 为数据库安装地址
 参考  https://gbasedbt.com/index.php/archives/493/
 
 编译 pdo_gbasedbt.os 
 参考 https://gbasedbt.com/index.php/archives/68/
 
 
 注意
 需要配置当前用户文件夹下面 的 bash_profile 文件
     
	 export GBASEDBTDIR=/opt/gbase
    export GBASEDBTSERVER=gbase01
    export ONCONFIG=onconfig.$GBASEDBTSERVER
    export PATH=$GBASEDBTDIR/bin:$GBASEDBTDIR/sbin:$GBASEDBTDIR/sbin:${PATH}
    export GBASEDBTSQLHOSTS=/opt/gbase/etc/sqlhosts
    export SERVER_LOCALE=zh_CN.utf8
    export DB_LOCALE=zh_CN.utf8
    export CLIENT_LOCALE=zh_CN.utf8
    export GL_USEGLU=1
    # export NODEFDAC=yes
    export DBDATE="Y4MD-"
    export DBACCESS_SHOW_TIME=1

同时需要编辑 PHP-FPM 的 systemd 服务文件

[Service]
    Environment="GBASEDBTDIR=/opt/gbasedbt"
    Environment="ODBCINI=/etc/odbc.ini"
    Environment="LD_LIBRARY_PATH=/opt/gbasedbt/lib:/opt/gbasedbt/lib/cli:/opt/gbasedbt/lib/esql:$LD_LIBRARY_PATH"
