阿里云服务器使用记录1 根据官网视频安装httpd的悲惨经历

这是阿里云教学视频的一张ppt
来自 Clouder认证课程：网站建设——部署与发布
以下80%是记录如何失败的执行第一句???

---

1. 远程连接

 ssh root@***.***.***.***

---

2. 安装httpd

# yum -y install httpd

提示

The program 'yum' is currently not installed. You can install it by typing:
apt install yum

安装yum

# apt install yum

提示

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package yum

输入

# sudo apt-get update

再次

# apt install yum

安装成功
再次

# yum -y install httpd

提示

There are no enabled repos.
 Run "yum repolist all" to see the repos you have.
 You can enable repos with yum-config-manager --enable

需要按照repo

https://source.android.com/source/downloading.html
（转存 https://blog.csdn.net/weixin_42319408/article/details/94855779)

按照官网提示进行到

# repo init -u https://android.googlesource.com/platform/manifest

这一步时提示

gpg: keyring `/root/.repoconfig/gnupg/secring.gpg' created
gpg: keyring `/root/.repoconfig/gnupg/pubring.gpg' created

fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle
fatal: error [Errno 99] Cannot assign requested address
fatal: cloning the git-repo repository failed, will remove '.repo/repo' 

未解决
再查到

https://www.cnblogs.com/dinphy/p/5669384.html
解决方法,先单独克隆repo,然后将git-repo里面的repo文件复制到bin目录，在同步源码的工作目录新建.repo文件夹，把git-repo重命名为repo复制到.repo目录下
git clone https://gerrit-googlesource.lug.ustc.edu.cn/git-repo
重新初始化：
repo init -u git://github.com/CyanogenMod/android.git -b cm-12.1
同步开始
repo sync -c -j8

目前已成功进行到同步步骤

repo sync -c -j8

卡住

百分比在15%~30%之间乱跳？
据说第一次同步要1～2小时，再等一会看看

第二天早晨
完蛋，中间断网了
…
把服务器重置了
…
连不上了

查看/Users/coconutnut/.ssh/known_hosts
把之前的密钥删了
重连成功
再来
