# build_iso

#### 介绍
构建iso镜像

#### 使用说明

1.  添加自定义文件
将文件拷贝到/tmp/cfg_openEuler/usr_file, 使用此目录为跟目录，例如

```bash
usr_file/
└── etc
    ├── bb
    └── bb_duan
```

2.  定制kernel cmdline
修改build_iso中的 image_config_kernel，例如：

```bash
image_config_kernel="rd.lvm.lv=openeuler/root rd.lvm.lv=openeuler/swap video=VGA-1:640x480-32@60me console=tty0 crashkernel=1024M,high smmu.bypassdev=0x1000:0x17 smmu.bypassdev=0x1000:0x15 video=efifb:off sched_steal_node_limit=4 kpti=off mitigation=off"
```

3.  启动时默认执行bash脚本
将文件拷贝到/tmp/cfg_openEuler/usr_install/hook/install_succ_hook
命名为 S00xxxx，例如：

```bash
#!/bin/bash

###############################################
#    Description: wait for reboot
#    Parameter:   param1:wait times
#    Return:      0-success, 1-failed
###############################################

# 增加的内容
touch /mnt/disk/root/aaaa
chroot /mnt/disk
echo "/root/aaaa" > /root/b
exit
###############


function INIT_Wait_Reboot()
{
    local count=$1
    while [ "${count}" -gt 0 ]
    do
        echo -e " ${count} \c"
        ((count--))
        sleep 1
    done
    echo ""
}

echo "The System will be reboot after 5 seconds."
INIT_Wait_Reboot 10

reboot

sleep 60

```

4、增加软件包设置need_rpms，例如：
```bash
need_rpms="mysql nginx"
```
