本博文对应地址: https://hceng.cn/2017/08/05/Linux开发环境配置及shell-script/#more
本文主要是以快速搭建环境为目标学习shell script。

之前写过一个Linux嵌入式开发环境搭建的博客，后面每次搭环境都翻来复制上面的代码。感觉就像记事本一样，还是有点用，这也是写博客的一点动力吧。
用了Linux也有段时间了，它的魅力也逐渐展现出来了。以前还在熟悉Linux命令的过程中，shell script就是个老虎，觉得没接触过，害怕，每次都绕开它。
直到这周遇到了ti的SDK，尝试一边百度，一边测它的脚本，感觉有点小入门了，于是想练习下。想到每次搭建环境重复操作的痛点，就拿它开刀吧。

0.环境搭建的几个方面

根据过去的经验，用虚拟机装好Ubuntu后，一般会做这样几个步骤：

1.安装vmware tools,以便复制粘贴和文件共享；
2.更新软件源，以便更快的下载软件；
3.安装及配置常用软件，比如：
　　3-1.安装git,方面后续的一些安装；
　　3-2.安装vim和简单配置；
　　3-3.安装ftp和简单配置；
　　3-4.安装nfs和简单配置；
　　3-5.安装samba和简单配置；
　　3-6.安装tmux、htop等；
4.安装开发所需的 g++等工具、库；

除了第一步，其它都计划用脚本实现。

在开发中，厌烦了每次编辑了驱动，都要拖进Linux主机进行编译，然后还要复制到开发板。
重新打造了工作流，只需要在电脑上操作三步：
编辑->make编译->insmod加载

Linux开发环境配置及shell script

1.检测当前环境

在运行脚本前，需要检测一些东西：

1.1检测网络状态

如果不能联网，后续的没必要做了。之前想过自动检测修复网络的，但想了想，网络的情况比较多，暂时搁置。而且刚装好虚拟机肯定是联网的，如果不能联网肯定是虚拟机设置的问题，也不是脚本能解决的。
为了方便打印醒目和更改用户名，这里先设置几个变量：
{% codeblock lang:bash%}
#define echo print color.
RED_COLOR=’\E[1;31m’
PINK_COLOR=’\E[1;35m’
YELOW_COLOR=’\E[1;33m’
BLUE_COLOR=’\E[1;34m’
GREEN_COLOR=’\E[1;32m’
END_COLOR=’\E[0m’

#set linux host user name.
user_name=hceng
{% endcodeblock %}

检测网络函数：
{% codeblock lang:bash%}
check_network() {
ping -c 1 www.baidu.com > /dev/null 2>&1
if [ ?−eq0];thenecho−e"? -eq 0 ];then echo -e "{GREEN_COLOR}Network ok.ENDCOLOR"elseecho−e"{END_COLOR}" else echo -e "{RED_COLOR}Network failure!${END_COLOR}"
exit 1
fi
}
{% endcodeblock %}
先ping一次百度，能够ping通就表示网络没问题。

1.2检测是否是root用户

很多操作都需要root权限，因此必须使用root用户权限运行脚本，这里先检测是否是root用户：
{% codeblock lang:bash%}

Check user must root.

check_root() {
if [ (id−u)!="0"];thenecho−e"(id -u) != "0" ]; then echo -e "{RED_COLOR}Error: You must be root to run this script, please use root.${END_COLOR}"
exit 1
fi
}
{% endcodeblock %}

1.3检测设置的用户是否存在

现在用的用户名是hceng，后面为了方便其它用户使用，所以在前面定义了个变量，改变变量就可以修改用户。但为了防止设置的用户在系统中不存在，这里需要进行检测。
{% codeblock lang:bash%}

Check set linux host user name.

check_user_name() {
cat /etc/passwd|grep $user_name
if [ ?−eq0];thenecho−e"? -eq 0 ];then echo -e "{GREEN_COLOR}Check the set user name OK.ENDCOLOR"elseecho−e"{END_COLOR}" else echo -e "{RED_COLOR}Check the set user name failure!${END_COLOR}"
exit 1
fi
}
{% endcodeblock %}

1.4检测运行结果

为检测某些命令，是否运行正常。
{% codeblock lang:bash%}
check_status() {
ret=?if["? if [ "ret" -ne “0” ]; then
echo -e “REDCOLORFailedsetup,aborting..{RED_COLOR}Failed setup, aborting..{END_COLOR}”
exit 1
fi
}
{% endcodeblock %}

1.5获取系统版本信息

后面更新源和装某些软件需要当前Ubuntu的版本代号。
{% codeblock lang:bash%}

Get the code name of the Linux host release to the caller.

get_host_type() {
local __host_type=$1
local the_host=lsb_release -a 2>/dev/null | grep Codename: | awk {'print $2'}
eval KaTeX parse error: Expected group after '_' at position 1: _̲_host_type="'the_host’"
}
{% endcodeblock %}

2.更新软件源

这里使用了阿里、网易和官方的三个源，应该没问题了。
修改配置文件的原则就是先备份再修改。同时为了防止脚本再次运行覆盖掉备份，还需要检测是否已经存在了备份。
{% codeblock lang:bash%}
#This function will update the source of the software.
update_software_source() {
local back_file=/etc/apt/sources.list.backup
if [ ! -e “$back_file” ];then
cp /etc/apt/sources.list $back_file
fi

{% endcodeblock %}

3.安装软件及配置

软件主要包括自己一般常用的软件，像vim、tmux、samba等。还有就是开发所需的g++、各种库。
其中git要在vim前面，因为vim的配置文件需要git下载。
{% codeblock lang:bash%}

Execute an action.

FA_DoExec() {
echo -e “BLUECOLOR==>Executing:′{BLUE_COLOR}==> Executing: '{@}’.${END_COLOR}”
eval [email protected] || exit $?
}

Install list software.

install_software() {
local install_software_list=(“git” “vim” “tmux” “htop” “vsftpd” “openssh-server” “nfs-kernel-server” “portmap” “samba”)
echo -e “PINKCOLORinstallsoftwarelist:{PINK_COLOR}install_software_list:{install_software_list[*]}.${END_COLOR}”

#install git
if (echo "${install_software_list[@]}" | grep -wq "git");then
	apt-get -y install git && echo -e "${BLUE_COLOR}git install completed.${END_COLOR}" 
fi

#install and configure vim
if (echo "${install_software_list[@]}" | grep -wq "vim");then
	apt-get -y install vim && vim_configure	&& echo -e "${BLUE_COLOR}vim install completed.${END_COLOR}" 
fi

#install tmux
if (echo "${install_software_list[@]}" | grep -wq "tmux");then
	apt-get -y install tmux && echo -e "${BLUE_COLOR}tmux install completed.${END_COLOR}" 
fi

#install htop
if (echo "${install_software_list[@]}" | grep -wq "htop");then
	apt-get -y install htop && echo -e "${BLUE_COLOR}htop install completed.${END_COLOR}" 
fi

#install and configure vsftpd
if (echo "${install_software_list[@]}" | grep -wq "vsftpd");then
	apt-get -y install vsftpd && ftp_configure && echo -e "${BLUE_COLOR}vsftpd install completed.${END_COLOR}" 
fi

#install openssh-server
if (echo "${install_software_list[@]}" | grep -wq "openssh-server");then
	apt-get -y install openssh-server && echo -e "${BLUE_COLOR}openssh-server install completed.${END_COLOR}" 
fi

#install and configure nfs-kernel-server
if (echo "${install_software_list[@]}" | grep -wq "nfs-kernel-server");then
	apt-get -y install nfs-kernel-server && nfs_configure && \
	/etc/init.d/nfs-kernel-server restart && echo -e "${BLUE_COLOR}nfs-kernel-server install completed.${END_COLOR}" 
fi

#install portmap
if (echo "${install_software_list[@]}" | grep -wq "portmap");then
	apt-get -y install portmap && echo -e "${BLUE_COLOR}portmap install completed.${END_COLOR}" 
fi

#install and configure samba
if (echo "${install_software_list[@]}" | grep -wq "samba");then
	apt-get -y install samba && samba_configure && echo -e "${BLUE_COLOR}samba install completed.${END_COLOR}" 
fi

3.1配置vim

vim的配置文件来自GitHub的Amir,我就不重复造*了。
这里只是先clone下来，然后执行安装脚本。这里值得一提的是执行脚本要指定用户运行，不然会以root用户的路径设置，导致脚本运行错误。
{% codeblock lang:bash%}

Configure vim form github.

vim_configure() {
git clone --depth=1 https://github.com/amix/vimrc.git /home/$user_name/.vim_runtime

touch /home/$user_name/.vim_runtime/my_configs.vim
echo ":set number" > /home/$user_name/.vim_runtime/my_configs.vim

chown -R $user_name /home/$user_name/.vim_runtime 
chmod u+x /home/$user_name/.vim_runtime/install_awesome_vimrc.sh
su - $user_name -s /home/$user_name/.vim_runtime/install_awesome_vimrc.sh

}
{% endcodeblock %}

3.2配置ftp

FTP主要是修改为可写。在使用MobaXterm SSH登陆后，可以直接通过左边的Sftp进行文件的传输，貌似这个可以不用配置了。
{% codeblock lang:bash%}

Configure ftp.

ftp_configure() {
sed -i ‘s/#loacl_enable=YES/loacl_enable=YES/g’ /etc/vsftpd.conf
sed -i ‘s/#write_enable=YES/write_enable=YES/g’ /etc/vsftpd.conf
}
{% endcodeblock %}

3.3配置nfs

在前面的工作流中，开发板直接运行Linux主机中交叉编译好的模块，是通过nfs实现的。因此需要开发板开机后就挂载nfs.
习惯在Linux主机中单独开辟一个路径作为工作目录，因此这里是设置的整个工作目录。
{% codeblock lang:bash%}

Configure nfs.

nfs_configure() {
local work_file=/work
if [ ! -d “$work_file” ];then
mkdir /work
fi
check_status

grep "/work" /etc/exports 1>/dev/null
if [ $? -ne 0 ];then
	sed -i '$a\/work  *(rw,sync,no_root_squash,no_subtree_check)' /etc/exports
fi

}
{% endcodeblock %}

3.4配置samba

samba也是实现前面工作流不可确少的一环。这样就不用每次修改代码后，通过ftp上传到Linux主机。
samba在Windows上的使用是：
先Windows+r，打开命令窗口，
然后输入：\\192.168.1.xx，
最后建议右键，映射网络驱动，方面后续打开。
测试中需要重启生效。
{% codeblock lang:bash%}

Configure samba.

samba_configure() {
local back_file=/etc/samba/smb.conf.bakup
if [ ! -e “$back_file” ];then
cp /etc/samba/smb.conf $back_file
fi
check_status

grep "/work" /etc/samba/smb.conf 1>/dev/null
if [ $? -ne 0 ];then
	sed -i \
    '$a[share_work]\n\
	path = \/work\n\
	available = yes\n\
	public = yes\n\
	guest ok = yes\n\
	read only = no\n\
	writeable = yes\n' /etc/samba/smb.conf
fi

/etc/init.d/samba restart
chmod -R 777 /work

}
{% endcodeblock %}
