vitess build on mac

两个步骤，1.环境准备 2.编译安装

Envrionment Prepare

1. Install Homebrew. If your /usr/local directory is not empty and you haven't yet used Homebrew, you need to run the following command:

   sudo chown -R $(whoami):admin /usr/local
   

2. If Xcode is installed (with Console tools, which should be bundled
   automatically since version 7.1), all the dev dependencies should be satisfied in this step. If Xcode isn't present, you'll need to install pkg-config.

   brew install pkg-config
   

3. Install etcd v3.0+. Remember to include etcd command on your path.

4. Run the following commands:

   brew install go ant automake libtool python git bison curl wget mysql57
   pip install --upgrade pip setuptools
   pip install virtualenv
   pip install MySQL-python
   pip install tox
   

5. The Vitess bootstrap script makes some checks for the go runtime, so it is recommended to have the following commands in your ~/.profile, ~/.bashrc, ~/.zshrc, or ~/.bash_profile:

   export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"
   export PATH=/usr/local/go/bin:$PATH
   export GOROOT=/usr/local/go
   

6. For the Vitess hostname resolving functions to work correctly, a new entry has to be added into the /etc/hosts file with the current LAN IP address of the computer (preferably IPv4) and the current hostname, which you get by typing the 'hostname' command in the terminal.

   It is also a good idea to put the following line to force the Go DNS resolver in your ~/.profile or ~/.bashrc or ~/.zshrc:

   export GODEBUG=netdns=go
   

Build Vitess

1. Navigate to the directory where you want to download the Vitess source code and clone the Vitess Github repo. After doing so, navigate to the src/vitess.io/vitess directory.

   cd $WORKSPACE
   git clone https://github.com/vitessio/vitess.git \
       src/vitess.io/vitess
   cd src/vitess.io/vitess
   

2. Set the MYSQL_FLAVOR:

# It is recommended to use MySQL56 even for MySQL 5.7 and 8.0. For MariaDB you can use MariaDB:
export MYSQL_FLAVOR=MySQL56

3. If your selected database installed in a location other than /usr/bin, set the VT_MYSQL_ROOT variable to the root directory of your MySQL installation:

   # For generic tarballs on Linux
   export VT_MYSQL_ROOT=/usr/local/mysql
   
   # On macOS with Homebrew
   export VT_MYSQL_ROOT=/usr/local/opt/mysql@5.7
   

   Note that the command indicates that the mysql executable should be found at /usr/local/opt/mysql@5.7/bin/mysql.

4. Run mysqld --version and confirm that you are running MySQL 5.7.

5. Build Vitess using the commands below. Note that the bootstrap.sh script needs to download some dependencies. If your machine requires a proxy to access the Internet, you will need to set the usual environment variables (e.g. http_proxy, https_proxy, no_proxy).

   Run the boostrap.sh script:

   BUILD_TESTS=0 ./bootstrap.sh
   ### example output:
   # skipping zookeeper build
   # go install golang.org/x/tools/cmd/cover ...
   # Found MariaDB installation in ...
   # creating git pre-commit hooks
   #
   # source dev.env in your shell before building
   

   # Remaining commands to build Vitess
   source ./dev.env
   make build
   

遇到的问题：

环境准备部分：

1. 不用先下载etcd，后面执行bootstrap脚本会安装

2. brew install go ant automake libtool python git bison curl wget mysql57

   先执行

   brew install go ant automake libtool git bison curl wget
   单独执行brew install mysql@57

   如果没有python，单独执行brew install python@2

3. pip install --user tox

   报错：ERROR: matplotlib 1.3.1 requires nose, which is not installed.
   ERROR: matplotlib 1.3.1 requires tornado, which is not installed.

   执行

   pip install nose

   pip install tornado

编译安装的问题：

1. bootstrap.sh执行安装zookeeper时

compile-test:
    [mkdir] Created dir: /Users/xiejinke1/Projects/gopath/dist/vt-zookeeper-3.4.14/zookeeper-3.4.14/build/test/classes

本机配置JDK1.8版本，参考：https://www.jianshu.com/p/072981dc9cc2

2. govendor sync时

Updating govendor dependencies...
# cd .; git clone https://github.com/aws/aws-sdk-go /Users/xiejinke1/Projects/gopath/.cache/govendor/github.com/aws/aws-sdk-go
正克隆到 '/Users/xiejinke1/Projects/gopath/.cache/govendor/github.com/aws/aws-sdk-go'...
error: RPC 失败。curl 18 transfer closed with outstanding read data remaining
fatal: 远端意外挂断了
fatal: 过早的文件结束符（EOF）
fatal: index-pack 失败

手动

git clone https://github.com/coreos/etcd $GOPATH/src/github.com
git clone https://github.com/aws/aws-sdk-go $GOPATH/src/github.com
git clone https://code.googlesource.com/google-api-go-client $GOPATH/src/google.golang.org/api

由于执行到这个步骤由于墙或者代码已经移动到github.com中，可以手动执行govendor sync -v 查看govendor在fetch什么，缺什么提前补充好。加快执行速度。

如果执行git clone 下载不下来，参考 https://www.jianshu.com/p/bb16ea7afdda 给git配置一个代理
