前言

书接上文【vsomeip】如何让vsomeip在双系统运行起来----(一)，继续讲述在双机上运行vsomeip所遇到的问题。

验证vsomeip可以在Host Linux和LXC 里面的Guest Linux之间进行通信。

验证vsomeip自带helloworld例程
创建helloworld的Service和client的配置文件
验证双机情况下vsomeip通信
验证LXC 内外系统的vsomeip通信

一、LXC是什么？

LXC是Linux系统里面用于虚拟化的一套机制，好像是在Linuxi系统上面隔离两个或者多个独立space。如果你的项目是基于Linux系统的，又有Container的需求，那不妨考虑LXC和Docker。
更多详细说明，网络上大把，这里不再赘述。

二、Linux LXC installation

LXC 安装起来似乎非常简单。。。

will@will-OptiPlex-7050:~/work$ ls /usr/share/lxc/templates/
lxc-busybox  lxc-download  lxc-local  lxc-oci

安装完LXC后，检查可用的模板非常少，并且没有Ubuntu要用的模板lxc-ubuntu，当务之急是解决模板缺失问题

will@will-OptiPlex-7050:~/work$ lxc -version

Command 'lxc' not found, but can be installed with:

sudo snap install lxd            # version 5.19-31ff7b6, or
sudo apt  install lxd-installer  # version 1
sudo apt  install lxd            # version 1:0.10

See 'snap info lxd' for additional versions.

lxc-centos     lxc-fedora-legacy  lxc-opensuse      lxc-slackware  lxc-voidlinux

此时，我们会看到LXC的模板库瞬间拉满，很多都出现了，关键我们心心念的lxc-ubuntu的模板也出来了。值得注意的是，如果你这一切实验或者操作都不是在ubuntu，就不能用ubuntu的模组，而是要找到你用的PC带的系统。

三、Container的创建

will@will-OptiPlex-7050:~/work/GB32960_framwork$ sudo lxc-create -n lxc -t ubuntu               //Create one container named lxc
Checking cache download in /var/cache/lxc/focal/rootfs-amd64 ...

Stuck here… don’t known the root cause

四、解决进入LXC console卡住的问题

Do the same steps on  another ubuntu 18.03, no stuck issue found, which seems we can verify all steps are right.  
will@ubuntu:~$ sudo lxc-console -n lxc

Connected to tty 1
Type <Ctrl+a q> to exit the console, <Ctrl+a Ctrl+a> to enter Ctrl+a itself

Ubuntu 18.04.6 LTS lxc pts/0

ubuntu@lxc:~$

不知道Ubuntu 20.04的LXC的console为什么一直进不去，自己感觉也无力再去解决这个bug。。。
了解到，通过SSH也同样可以登录LXC，于是开整。

1. 安装SSH

will@will-OptiPlex-7050:/tmp$ sudo lxc-attach -n will
root@will:/tmp#cd ..
root@will:/# sudo apt install openssh-server
Reading package lists... Done
Building dependency tree

openssh-server is already the newest version (1:8.2p1-4ubuntu0.9).

exit
will@will-OptiPlex-7050:/tmp$ sudo lxc-ls --fancy
NAME STATE   AUTOSTART GROUPS IPV4       IPV6 UNPRIVILEGED 
will RUNNING 0         -      10.0.3.232 -    false

这里知道LXC里面的Ubuntu的IP地址是10.0.3.232。

will@will-OptiPlex-7050:/tmp$ ssh ubuntu@10.0.3.232
The authenticity of host '10.0.3.232 (10.0.3.232)' can't be established.

lxc-console stuck at login, but we can use SSH to login.:-）

2. Share file with contianer

Use to SCP to copy files from HOST ubuntu to GUEST ubunt.

3. Run APP in contianer

ubuntu@will:/tmp/examples/hello_world/build$ ./hello_world_client 
./hello_world_client: error while loading shared libraries: libvsomeip3.so.3: cannot open shared object file: No such file or directory

Two methods to fix this issue.

Method 1:
will@will-OptiPlex-7050:~/work$ sudo apt-get install libboost-system-dev libboost-thread-dev libboost-log-dev
will@will-OptiPlex-7050:~/work$ sudo apt-get install asciidoc source-highlight doxygen graphviz
will@will-OptiPlex-7050:~/work$ sudo apt-get install gcc g++ make

Method 2:
Use SCP command to cope these .so file to container.
scp -r libvsomeip3.so.3/ ubuntu@10.0.3.232:/usr/local/lib/lib64
scp -r libvsomeip3-e2e.so/ ubuntu@10.0.3.232:/usr/local/lib/lib64
scp -r libvsomeip3-sd.so/ ubuntu@10.0.3.232:/usr/local/lib/lib64

Push all vsomeip folder to container internal.

此处又报错了，看样子要删掉build目录后，重新编译vsomeip一下。

总结

在验证vsomeip在LXC container内外系统通信的过程中，确实遇到各种各种的问题，这可能也是Linux的最大特点，但都要用直接或者间接的方法来解决掉了。
本文就写到这里，算是把LXC里面的环境弄好，vsomeip编译好，后面将是本次学习的一个重要节点，就是验证LXC内外系统vsomeip的通信。
