# Ironfish铁鱼挖矿教程 CentOS 8 By [sddcg](https://paragraph.com/@sddcg) · 2021-12-07 --- Ironfish 铁鱼挖矿已经开始了，但官方的教程实在不敢恭维，官方建议的docker我觉得性能会低，所以在CentOS下，基于源码自行编译。经过测试CentOS7存在大量问题，安装很不方便，强烈建议使用CentOS8. > 首先准备一台服务器，CPU核心数要多一些，8核+，内存要求不高，8G就差不多 > > 提供付费安装服务（微信：t52861700 注明付费装铁鱼）， 200元一台（量大从优） 1. 安装 node.js 16 dnf module install nodejs:16 > centos8以前的版本没有dnf ，也可以手动下载安装 nodejs > > wget https://nodejs.org/dist/v16.13.1/node-v16.13.1-linux-x64.tar.xz > xz -d node-v16.13.1-linux-x64.tar.xz > tar -xvf node-v16.13.1-linux-x64.tar > ln -s /root/node-v16.13.1-linux-x64/bin/node /usr/bin/node > ln -s /root/node-v16.13.1-linux-x64/bin/npm /usr/bin/npm > ln -s /root/node-v16.13.1-linux-x64/bin/npx /usr/bin/npx > export PATH=/root/node-v16.13.1-linux-x64/bin/:$PATH > echo 'export PATH=/root/node-v16.13.1-linux-x64/bin/:$PATH' >> ~/.bashrc > source ~/.bashrc > 2. 安装gcc yum install gcc gcc-c++ make 3. 安装rust curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh source $HOME/.cargo/env 4. 安装 yarn npm install --global yarn 5. 下载官方源代码 cd /root git clone https://github.com/iron-fish/ironfish.git chown -R root ironfish > 如果没有git，通过一下命令安装 > > yum install git > > clone较慢的话，也可以自己下载后解压缩 > > wget https://github.com/iron-fish/ironfish/archive/refs/heads/master.zip > yum install -y unzip zip > unzip ironfish-master.zip > mv ironfish-master ironfish > 6. 编译源码 cd /root/ironfish yarn install yarn build cd /root/ironfish/ironfish-cli/ yarn build > 有些系统没有自带python，如果提示python错误，请安装python3.6 > 感谢老毕反馈的问题，如果编译源码后，在执行ironfish的相关命令出现 xxx is not a ironfish command 这类错误，可以执行 > > cd /root/ironfish > yarn install > yarn build > 7. 启动节点（初次启动要同步数据比较慢） cd /root/ironfish/ironfish-cli/ yarn ironfish start > 窗口不要关闭，或者把启动命令修改为后台方式 > > nohup yarn ironfish start >nohup.log & 8. 配置帐号（与官网注册一致） yarn ironfish config:set blockGraffiti "sddcg" > 双引号能填写自己在官网注册的帐号 9. 再开一个终端窗口开启挖矿 cd /root/ironfish/ironfish-cli/ yarn ironfich miners:start -t CPU核心数 或 yarn ironfich miners:start -t -1 > 窗口不要关闭，或者把启动命令修改为后台方式 nohup yarn ironfich miners:start -t -1 >mine.log & 10. 官网查看积分 [https://testnet.ironfish.network/leaderboard](https://testnet.ironfish.network/leaderboard) > 每次登录都会发邮件，需要到邮箱点击链接完成登录 > > 在search框输入自己的帐号后就能过滤自己的帐号，然后点击进入就可以查看积分情况 11. 水龙头领币 > 目前水龙头好像有问题，领不到 cd /root/ironfish/ironfish-cli/ yarn ironfish faucet 12. 关于服务器，大家可以去白嫖一些云服务器厂商的免费试用款 如华为云，就提供4核8G 15天免费用 13. 查看状态 cd /root/ironfish/ironfish-cli/ yarn ironfish status -f 下图的 mined前的数字表示你挖到的数量 ![挖矿状态](https://storage.googleapis.com/papyrus_images/48f23e83dd60854919845af20f154e7b587314ada523e91dc74991604efc6edb.png) 挖矿状态 Cmake问题 ------- yum install centos-release-scl devtoolset-8-gcc* scl enable devtoolset-8 bash source /opt/rh/devtoolset-8/enable yum install cmake3 alternatives --install /usr/local/bin/cmake cmake /usr/bin/cmake 10 \ --slave /usr/local/bin/ctest ctest /usr/bin/ctest \ --slave /usr/local/bin/cpack cpack /usr/bin/cpack \ --slave /usr/local/bin/ccmake ccmake /usr/bin/ccmake \ --family cmake alternatives --install /usr/local/bin/cmake cmake /usr/bin/cmake3 20 \ --slave /usr/local/bin/ctest ctest /usr/bin/ctest3 \ --slave /usr/local/bin/cpack cpack /usr/bin/cpack3 \ --slave /usr/local/bin/ccmake ccmake /usr/bin/ccmake3 \ --family cmake alternatives --config cmake openssl问题 --------- yum install openssl11 export OPENSSL_ROOT_DIR='/usr/lib64/openssl11' echo 'export OPENSSL_ROOT_DIR=/usr/lib64/openssl11' >> ~/.bashrc export OPENSSL_INCLUDE_DIR='/usr/include/openssl11/openssl' echo 'export OPENSSL_INCLUDE_DIR=/usr/lib64/openssl11/openssl' >> ~/.bashrc source ~/.bashrc Updating crates.io index 速度慢的解决办法 ================================= 修改 $HOME/.cargo/config #

创建账号 create 时可以设置账号名字 yarn ironfish accounts:create # 修改使用某个账号进行挖矿，账号对应钱包 yarn ironfish accounts:use xxx # 账号导出 yarn ironfish accounts:export xxx /root/xxx.accounts # 账号导入 yarn ironfish accounts:import /root/xxx.accounts # 查看余额 yarn ironfish accounts:balance 本教程更新说明 ------- 将 svn下载源码的方式调整为使用 git安装 1. 安装subversion 2. 下载官方源代码 cd /root svn checkout "https://github.com/iron-fish/ironfish.git" --- *Originally published on [sddcg](https://paragraph.com/@sddcg/ironfish-centos-8)*
