准备编译安装HAProxy的基础环境

sudo apt install make gcc build-essential libssl-dev zlib1g-dev libpcre3 libpcre3-dev libsystemd-dev libreadline-dev -y

编译安装lua

lua为HAProxy支持基于其实现功能扩展
注：HAProxy要求的lua最低版本为5.3

sudo wget -P /usr/local/src/ http://www.lua.org/ftp/lua-5.3.5.tar.gz
cd /usr/local/src/
sudo tar xf lua-5.3.5.tar.gz
cd lua-5.3.5/src/
sudo make linux

查看编译后的版本

surou@DESKTOP-CRS8RL6:/usr/local/src/lua-5.3.5/src$ ./lua -v
Lua 5.3.5  Copyright (C) 1994-2018 Lua.org, PUC-Rio

编译安装HAProxy

安装基础环境

sudo apt install iproute2 ntpdate tcpdump telnet traceroute nfs-kernel-server nfs-common lrzsz tree openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev  gcc openssh-server iotop unzip libreadline-dev libsystemd-dev

clone haproxy

git clone https://github.com/haproxy/haproxy.git
git checkout v2.3-dev5

编译源代码

make -j `lscpu |awk 'NR==4{print $2}'` ARCH=x86_64 TARGET=linux-glibc USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1 USE_CPU_AFFINITY=1 USE_LUA=1 LUA_INC=/usr/local/src/lua-5.3.5/src/ LUA_LIB=/usr/local/src/lua-5.3.5/src/ PREFIX=/apps/haproxy && make install PREFIX=./dist/haproxy

编译完，查看当前目录

cd dist/haproxy/sbin

查看版本

./haproxy -v
surou@DESKTOP-CRS8RL6:~/dist/haproxy/sbin$ ./haproxy -v
HA-Proxy version 2.3-dev5-7faeea-1 2020/09/26 - https://haproxy.org/

Error 3010004: Invalid authority

 2020-09-27　  Surou　  阅读 　  EOS-新手问答　  0 评论

当设置一个账户的权限为多个账户时

cleos set account permission bcskillsurou active  '{"threshold":1,"keys":[{"key":"EOS5bu13CujrEUdKB57LnvihUAqkdUycwSz2p7vPuac7vNBvfh7M7","weight":1}],"accounts":[{"permission":{"actor":"222222222222","permission":"eosio.code"},"weight":1},{"permission":{"actor":"111111111111","permission":"eosio.code"},"weight":1}],"waits":[{"wat_sec":1,"weight":1}]}'  owner -p bcskillsurou

报错如下

Error 3010004: Invalid authority
Ensure that your authority JSON is valid follows the following format!
{
  "threshold":      <INTEGER [1-2^32): the threshold that must be met to satisfy this authority>,

      "weight":     <INTEGER [1-2^16): satisfying the delay contributes this to satisfying the threshold>
    }
    ...
  ]
}

Error Details:
Authority failed validation! ensure that keys, accounts, and waits are sorted and that the threshold is valid and satisfiable!

解决问题

将添加的accounts按照ascii顺序添加
例如上面的例子，先添加 111111111111 再添加 222222222222

cleos set account permission bcskillsurou active  '{"threshold":1,"keys":[{"key":"EOS5bu13CujrEUdKB57LnvihUAqkdUycwSz2p7vPuac7vNBvfh7M7","weight":1}],"accounts":[{"permission":{"actor":"111111111111","permission":"eosio.code"},"weight":1},{"permission":{"actor":"222222222222","permission":"eosio.code"},"weight":1}],"waits":[{"wat_sec":1,"weight":1}]}'  owner -p bcskillsurou

EOS js name To Uint64 OR Uint64 to name

源代码仓库地址：
https://github.com/bcskill/eosjs-name

演示地址
Try on run-kit https://npm.runkit.com/eosjs-account-name

测试代码
// name To Uint64

const eosjsAccountName = require("eosjs-account-name")
const n = eosjsAccountName.nameToUint64('eosio');
console.log('eosio to uint64: ' + n);
console.log('uint64 to name: ' + eosjsAccountName.uint64ToName(n));

// Uint64 to name

const uint64 = '6138663577826885632';
const name = eosjsAccountName.uint64ToName(uint64);

EOS 编译 llvmWARshim error

 2020-09-14　  Surou　  阅读 　  EOS-新手问答　  0 评论

编译EOS2.x版本时，由于使用WSL，或者Windows git 操作过，很容易把软连接丢了，所以报错如下

/eos/libraries/chain/webassembly/eos-vm-oc/llvmWARshim.llvmwar:1:1: error: ‘llvmWARshim’ does not name a type

 ^~~~~~~~~~~
libraries/chain/CMa

手动修复软连接

cd /eos/libraries/chain/webassembly/eos-vm-oc
rm llvmWARshim.llvmwar
ln -s llvmWARshim.cpp llvmWARshim.llvmwar

修复后ll查看如下

llvmWARshim.llvmwar -> llvmWARshim.cpp*
