Ubuntu--C++补全代码

概要：每次安装完虚拟机时，都要配置自己的环境，好多问题需要一个一个的寻找答案，浪费自己的时间，所以总结了一下留给以后参考使用

一、安装完成如需使用root身份登录，可打开终端输入以下命令：

# 设置root密码

sudo passwd root

#切换到root用户

sudo -s

想要在登录界面使用root身份登录，可编辑/etc/lightdm/目录下的lightdm.conf文件，如没有此文件，直接创建

/usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf

1.编辑/usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf

vim /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf

内容如下

[SeatDefaults]

autologin-user=root

user-session=ubuntu

greeter-show-manual-login=true

allow-guest=false

2.编辑 /root/.profile

vim /root/.profile

打开文件后找到“mesg on”

将其更改为“tty -s && mesg n”

3.用reboot命令重启即可

二、安装Openssh

1、Ubuntu 下安装OPenSSHServer 

sudo apt-get install openssh-server

2、对openssh server 进行配置

vim /etc/ssh/sshd_config

找到permitRootLogin on一行，改为PermitRootLogin Yes

3、重启openssh server

service sshd restart

三、ssh client 报 algorithm negotiation Failed的解决方法之一

1、修改sshd的配置文件 /etc/ssh/sshd_config

Ciphers aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-cbc,arcfour128,arcfour256,arcfour,blowfish-cbc,cast128-cbc

MACshmac-md5,hmac-sha1,[e-mail],hmac-ripemd160,hmac-sha1-96,hmac-md5-96

KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group1-sha1,[e-mail]

2、重启服务

sudo /etc/init.d/ssh restart 重启sshd服务后，即可正常连接。

四、同步时间

安装ntpdate工具

# sudo apt-get install ntpdate

1.首先查看时区：

date -R

Tue,17 Dec 2013 18:23:01+0800

如果要修改时区，执行sudo tzselect

2.选择区域：亚洲

sudo tzselect

Please identify a locationso that time zone rules can be set correctly.

Please select a continentor ocean.

1) Africa

2) Americas

3) Antarctica

4) Arctic Ocean

5) Asia

#? 5

3.选择国家：中国

Please select a country.

9) China 26) Laos 43) Taiwan

#? 9

4.选择时区：北京时间

Please select one of thefollowing time zone regions.

1) east China - Beijing,Guangdong,Shanghai,etc.

2) Heilongjiang (exceptMohe),Jilin

#? 1

5.确认验证：

Is the above informationOK?

1) Yes

2) No

#? 1

6.复制文件到/etc目录下

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

7.更新时间

sudo ntpdate time.windows.com

五、安装YOucompleteme

1、卸载老版本vim

 sudo apt-get remove vim 

 sudo apt-get remove vim-runtime 

 sudo apt-get remove gvim 

 sudo apt-get remove vim-tiny 

 sudo apt-get remove vim-common 

 sudo apt-get remove vim-gui-common 

2、下载vim最新源码

cd ~

git clonehttps://github.com/vim/vim.git

3、进入vim

cd vim

设置Vim源码的编译属性

./configure--with-features=huge --enable-rubyinterp --enable-pythoninterp --with-python-config-dir=/usr/lib/python2.7/config-i386-linux-gnu/--enable-perlinterp --enable-gui=gtk2--enable-cscope --enable-luainterp --enable-perlinterp --enable-multibyte --prefix=/usr

需要重新配置可 输入makedistclean#清理一下上一次编译生成的所有文件

其中参数说明如下：

--with-features=huge：支持最大特性

--enable-rubyinterp：启用Vim对ruby编写的插件的支持

--enable-pythoninterp：启用Vim对python编写的插件的支持

--enable-luainterp：启用Vim对lua编写的插件的支持

--enable-perlinterp：启用Vim对perl编写的插件的支持

--enable-multibyte：多字节支持 可以在Vim中输入中文

--enable-cscope：Vim对cscope支持

--enable-gui=gtk2：gtk2支持,也可以使用gnome，表示生成gvim

--with-python-config-dir=/usr/lib/python2.7/config-i386-linux-gnu/指定 python 路径

--prefix=/usr：编译安装路径

sudo make VIMRUNTIMEDIR=/usr/share/vim/vim74

sudo make install

4、安装YouCompleteMe

a、下载

git clone --recursive git://github.com/Valloric/YouCompleteMe

如果执行该命令没报错,就ok了. 但是中途有可能会断掉,可以 cd 到YouCompleteMe,然后反复用如下命令再次进行下载:

git submodule update --init --recursive

这个命令下载时间挺长的

b、 安装

cd ~/.vim/bundle/YouCompleteMe

./install.py --clang-completer

成功的log如下:

-- [download 99% complete]

-- [download 100% complete]

Using libclang to provide semantic completion for C/C++/ObjC

c、配置

.vimrc中加入:

" YouCompleteMe

set runtimepath+=~/.vim/bundle/YouCompleteMe

let g:ycm_collect_identifiers_from_tags_files = 1 " 开启 YCM 基于标签引擎

let g:ycm_collect_identifiers_from_comments_and_strings = 1 " 注释与字符串中的内容也用于补全

let g:syntastic_ignore_files=[".*\.py$"]

let g:ycm_seed_identifiers_with_Syntax = 1 " 语法关键字补全

let g:ycm_complete_in_comments = 1

let g:ycm_confirm_extra_conf = 0

let g:ycm_key_list_select_completion = ['<c-n>','<Down>'] " 映射按键,没有这个会拦截掉tab,导致其他插件的tab不能用.

let g:ycm_key_list_prevIoUs_completion = ['<c-p>','<Up>']

let g:ycm_complete_in_comments = 1 " 在注释输入中也能补全

let g:ycm_complete_in_strings = 1 " 在字符串输入中也能补全

let g:ycm_collect_identifiers_from_comments_and_strings = 1 " 注释和字符串中的文字也会被收入补全

let g:ycm_global_ycm_extra_conf='~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'

let g:ycm_show_diagnostics_ui = 0 " 禁用语法检查

inoremap <expr> <CR> pumvisible() ?"\<C-y>" : "\<CR>" | " 回车即选中当前项

nnoremap <c-j> :YcmCompleterGoToDeFinitionElseDeclaration<CR>|" 跳转到定义处

"let g:ycm_min_num_of_chars_for_completion=2 " 从第2个键入字符就开始罗列匹配项

其中~/.vim/bundle/YouCompleteMe 为下载 YouCompleteMeu 的路径.

六、安装NERDTree

wget http://www.vim.org/scripts/download_script.PHP?src_id=17123 -Onerdtree.zip

unzip nerdtree.zip

mkdir -p ~/.vim/{plugin,doc}

cp plugin/NERD_tree.vim ~/.vim/plugin/

cp doc/NERD_tree.txt ~/.vim/doc/

安装好后，命令行中输入vim，打开vim后，在vim中输入:NERDTree，你就可以看到NERDTree的效果了。
