Question

使用Capistrano将Rails应用程序部署到运行Apache且启用了Passenger的Ubuntu VM。

我按照本教程：https://www.phusionpassenger.com/library/install/apache/install/oss/trusty/进行了一些更改，因为我在17.04而不是14.04 LTS。

passenger-config validate-install表示Passenger和Apache的一切看起来都很好。 passenger-memory-stats显示Passenger和Apache进程。

我已多次sudo apache2ctl restart编辑，没有任何警告。但是passenger-status，以及Capistrano运行的passenger-config restart-app，报告说Passenger“似乎没有运行”。所以我的部署停止了。

机器上只有一个Ruby，使用ruby-install安装ruby-2.4.1。如果版本不匹配，我有apt-get update和upgrade d。

Apache日志不会显示任何错误，当然也不会与Passenger相关。

为什么Passenger内部不同意，说它既配置正确又有流程正在运行，但后来说它没有运行？

我需要自定义实例注册表目录，如Tony Vincent所建议的那样：

服务器上的

/etc/apache2/mods-enabled/passenger.conf：

    pragma solidity ^0.4.11;

interface IERC20 {
    function totalSupply() constant returns (uint256 totalSupply);
    function balanceOf(address _owner) constant returns (uint256 balance);
    function transfer(address _to, uint256 _value) returns (bool success);
    function transferFrom(address _from, address _to, uint256 _value) returns (bool success);
    function approve (address _spender, uint256 _value) returns (bool success);
    function allowance(address _owner, address _spender) constant returns (uint256 remaining);
    event Transfer(address indexed _from, address indexed_to, uint256 _value);
    event Approval(address indexed_owner, address indexed_spender, uint256 _value);
}
contract SampleToken is IERC20 {

    using SafeMath for uint256;
    uint public _totalSupply = 10000000;

    string public constant symbol ="SAMP";
    string public constant name = "Sample Token";
    uint8 public constant decimals = 3;

    //1 ether = 350 SAMP
    uint256 public constant RATE = 350;

    address public owner;



    mapping(address => uint256) balances;
    mapping(address => mapping(address => uint256)) allowed;

    function () payable {
        createTokens();
    }

    function SampleToken () {
        owner = msg.sender;
    }

    function createTokens() payable {
        require(msg.value > 0);

        uint256 tokens = msg.value.mul(RATE);
        balances[msg.sender] = balances[msg.sender].add(tokens);
        _totalSupply = _totalSupply.add(tokens);

        owner.transfer(msg.value);
    }

    function totalSupply() constant returns (uint256 _totalSupply) {
        return _totalSupply;

    }

    function balanceOf(address _owner) constant returns (uint256 balance) {
        return balances[_owner]; 
    }

    function transfer(address _to, uint256 _value) returns (bool success) {
        require(
          balances[msg.sender] >= _value
          && _value > 0
        );
        balances[msg.sender] -= balances[msg.sender].sub(_value);
        balances[_to] = balances[_to].add(_value);
        Transfer(msg.sender, _to, _value);
        return true;
    }

    function transferFrom(address _from, address _to, uint256 _value) returns (bool success) {
        require(
            allowed[_from][msg.sender] >= _value
            && balances[_from] >= _value
            && _value > 0
        );
        balances[_from] = balances[_from].sub( _value);
        balances[_to] = balances [_to].add(_value);
        allowed[_from][msg.sender] = allowed[_from][msg.sender].sub(_value);
        Transfer(_from, _to, _value);
        return true;
    }

    function approve (address _spender, uint256 _value) returns (bool success) {
        allowed[msg.sender][_spender] =_value;
        Approval(msg.sender, _spender, _value);
        return true;
    }

    function allowance(address _owner, address _spender) constant returns (uint256 remaining) {
        return allowed[_owner][_spender];
    }

    event Transfer(address indexed _from, address indexed_to, uint256 _value);
    event Approval(address indexed_owner, address indexed_spender, uint256 _value);
    function mul(uint256 a, uint256 b) internal constant returns (uint256) {
    uint256 c = a * b;
    assert(a == 0 || c / a == b);
    return c;
  }
  function bytes32ToString(bytes32 x) constant returns (string) {
        bytes memory bytesString = new bytes(32);
        uint charCount = 0;
        for (uint j = 0; j < 32; j++) {
            byte char = byte(bytes32(uint(x) * 2 ** (8 * j)));
            if (char != 0) {
                bytesString[charCount] = char;
                charCount++;
            }
        }
        bytes memory bytesStringTrimmed = new bytes(charCount);
        for (j = 0; j < charCount; j++) {
            bytesStringTrimmed[j] = bytesString[j];
        }
        return string(bytesStringTrimmed);
    }

}

library SafeMath {
  function mul(uint256 a, uint256 b) internal constant returns (uint256) {
    uint256 c = a * b;
    assert(a == 0 || c / a == b);
    return c;
  }

  function div(uint256 a, uint256 b) internal constant returns (uint256) {
    // assert(b > 0); // Solidity automatically throws when dividing by 0
    uint256 c = a / b;
    // assert(a == b * c + a % b); // There is no case in which this doesn't hold
    return c;
  }

  function sub(uint256 a, uint256 b) internal constant returns (uint256) {
    assert(b <= a);
    return a - b;
  }

  function add(uint256 a, uint256 b) internal constant returns (uint256) {
    uint256 c = a + b;
    assert(c >= a);
    return c;
  }
}

在Rails应用程序中

config / deploy / production.rb：

PassengerInstanceRegistryDir /home/MYUSER/passenger_temp

Answer 2

很抱歉对此有所了解，但您是否在ubuntu服务器（而非osx）上运行passenger-config validate-install？ passenger-memory-stats和sudo apache2ctl restart相同。

基于/tmp没有passenger.randomstring目录，听起来好像是混淆了本地和远程命令。 /tmp是Ubuntu上PassengerInstanceRegistryDir的默认位置，因此如果Passenger正在运行，那么/tmp中的目录应该以{{1}}开头。

乘客似乎没有运行（Capistrano / Rails / Apache / Ubuntu）
