PlatON官網上主要支持在 Ubuntu 和 Windows 環境中編譯部署,可是也會有在CentOS上編譯部署的須要。本文主要介紹了在CentOS上的環境準備、編譯生成可執行文件和運行節點程序的過程。PlatON 官方代碼庫更新速度較快,有可能官方代碼作出了一些設置變化,若是有步驟不能正確執行,能夠參考 PlatON 官網具體信息。c++
Ubuntu在社區中很流行,但CentOS在企業級市場中佔有較大優點。目前,CentOS在AWS、阿里雲、UCloud 雲服務商中可以使用的最高官方版本是CentOS 7.5。git
本文就在CentOS 7.5下編譯部署PlatON。github
由於Platon的WASM庫和MPC庫依賴,開發和編譯環境須要支持C++14。GCC 6.1版本以上是默認支持C++14。 https://www.gnu.org/software/gcc/projects/cxx-status.html#cxx14golang
CentOS 7.5的默認GCC版本爲4.8.5,開發和編譯Platon須要升級GCC。Redhat官方的升級方法是經過devtoolset。web
https://access.redhat.com/solutions/19458編程
http://mirror.centos.org/centos/7/sclo/x86_64/rh/devtoolset-7/json
https://www.softwarecollections.org/en/scls/rhscl/devtoolset-7/
考慮以上的發佈時間順序、相互具體版本要求,選擇在CentOS 7.5中安裝devtoolset 7。
將如下33個rpm拷貝到一個目錄中,再執行:

$ sudo rpm -ivh dos2unix-6.0.3-7.el7.x86_64.rpm
Platon git倉庫代碼
$ go get github.com/PlatONnetwork/PlatON-Go
更新代碼
$ go get -u github.com/PlatONnetwork/PlatON-Go
$ cd build $ dos2unix *.sh $ chmod 755 *.sh
下載地址 https://download.platon.network/mpclib.tar.gz
$ tar xf mpclib.tar.gz $ mv mpclib $GOPATH/src/github.com/PlatONnetwork/PlatON-Go/
每次進bash須要手動切換GCC版本到 7.3.1
$ scl enable devtoolset-7 bash
或者直接設置在環境配置中,這樣每次打開bash默認是GCC 7.3.1
$ vi ~/.bashrc source scl_source enable devtoolset-7
添加mpclib中的依賴包
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$GOPATH/src/github.com/PlatONnetwork/PlatON-Go/mpclib $ echo $LD_LIBRARY_PATH /opt/rh/devtoolset-7/root/usr/lib64:/opt/rh/devtoolset-7/root/usr/lib:/opt/rh/devtoolset-7/root/usr/lib64/dyninst:/opt/rh/devtoolset-7/root/usr/lib/dyninst:/opt/rh/devtoolset-7/root/usr/lib64:/opt/rh/devtoolset-7/root/usr/lib:/home/wxuser/work/golang/src/github.com/PlatONnetwork/PlatON-Go/mpclib $ cd PlatON-Go/
$ make platon-with-mpc > ~/temp/make_platon.txt $ make all-with-mpc > ~/temp/make_all.txt
編譯後生成的可執行程序在 build/bin/ 中。
將生成的可執行程序拷貝到節點啓動目錄
$ cd build $ cp -R bin/ ~/platon-node
$ make clean $ rm -rf build/_workspace/*
