go使うための環境構築メモです。EC2で自分が環境構築したときのログをメモとして残しておきます。

zshのインストール

いきなりですがgoと関係ないですｗ

zshに慣れていこうと思い、ついでにインストールして使うようにしてます。

・sudo apt-get update

・sudo apt-get install zsh

・zshと入力後に2をえらぶ

・which zshでパス確認

・sudo chsh ubuntuで上のパスをいれる

ubuntu@MyEC2:~$ sudo apt-get install zsh

ubuntu@MyEC2:~$ zsh

This is the Z Shell configuration function for new users,

zsh-newuser-install.

You are seeing this message because you have no zsh startup files

(the files .zshenv, .zprofile, .zshrc, .zlogin in the directory

~). This function can help you with a few settings that should

make your use of the shell easier.

You can:

(q) Quit and do nothing. The function will be run again next time.

(0) Exit, creating the file ~/.zshrc containing just a comment.

That will prevent this function being run again.

(1) Continue to the main menu.

(2) Populate your ~/.zshrc with the configuration recommended

by the system administrator and exit (you will need to edit

the file by hand, if so desired).

goのインストール

こちらを参照しながら実施。

以下のリンクからgo.linux.amd64.tar.gzのリンクをコピー。

ここではgo1.11.4.linux-amd64.tar.gzとします。

sudo tar -C /usr/local -xzf go1.11.4.linux-amd64.tar.gz

vim $HOME/.zshrcで以下を追記

1 2	export GOPATH=$HOME/go export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin

その後source $HOME/.zshrcでOK

go versionで確認します。

vim-goのインストール

vimでgoのコードを書くのでvimをカスタマイズします。

まず以下２つのコマンドを実行。

1 2	curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim git clone https://github.com/fatih/vim-go.git ~/.vim/plugged/vim-go

以下コマンドで.vimrcを編集。いまのところ使っている自分の設定が↓です。

vim ~/.vimrc

call plug#begin()

Plug 'fatih/vim-go'

Plug 'fatih/molokai'

Plug 'SirVer/ultisnips'

Plug 'nathanaelkane/vim-indent-guides'

call plug#end()

"Plug 'fatih/vim-go'

let g:go_version_warning = 0

let g:go_fmt_autosave = 0

"Plug 'fatih/molokai'

let g:go_highlight_functions = 1

let g:go_highlight_methods = 1

let g:go_highlight_structs = 1

let g:rehash256 = 1

let g:molokai_original = 1

colorscheme molokai

"Plug 'nathanaelkane/vim-indent-guides'

let g:UltiSnipsExpandTrigger="<tab>"

let g:UltiSnipsJumpForwardTrigger="<tab>"

let g:UltiSnipsJumpBackwardTrigger="<s-tab>"

"Plug 'nathanaelkane/vim-indent-guides'

let g:indent_guides_enable_on_vim_startup = 1

最後にvim起動して:PlugInstallと入力してenterで完了。

ubuntu@MyEC2 ~ % curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

なんでdocker使わなかったんだろう？ｗ

ま、まあいいやｗ

そ、そのうちdockerにする可能性も無きにしも非ず。
