workerman 学习记录

Linux系统环境检测

Linux系统可以使用以下脚本测试本机PHP环境是否满足WorkerMan运行要求。 

curl -Ss http://www.workerman.net/check.php | php

check.php

<?php
$version_ok = $pcntl_loaded = $posix_loaded = false;
if (version_compare(phpversion(), "5.3.3", ">=")) {
    $version_ok = true;
}
if (in_array("pcntl", get_loaded_extensions())) {
    $pcntl_loaded = true;
}
if (in_array("posix", get_loaded_extensions())) {
    $posix_loaded = true;
}

function check($val)
{
    if ($val) {
        return "\033[32;40m [OK] \033[0m\n";
    } else {
        return "\033[31;40m [fail] \033[0m\n";
    }
}

echo "PHP Version >= 5.3.3                 " . check($version_ok);

echo "Extension pcntl check                " . check($pcntl_loaded);

echo "Extension posix check                " . check($posix_loaded);

$check_func_map = array(
    "stream_socket_server",
    "stream_socket_client",
    "pcntl_signal_dispatch",
    "pcntl_signal",
    "pcntl_alarm",
    "pcntl_fork",
    "posix_getuid",
    "posix_getpwuid",
    "posix_kill",
    "posix_setsid",
    "posix_getpid",
    "posix_getpwnam",
    "posix_getgrnam",
    "posix_getgid",
    "posix_setgid",
    "posix_initgroups",
    "posix_setuid",
    "posix_isatty",
);
// 获取php.ini中设置的禁用函数
if ($disable_func_string = ini_get("disable_functions")) {
    $disable_func_map = array_flip(explode(",", $disable_func_string));
}
// 遍历查看是否有禁用的函数
foreach ($check_func_map as $func) {
    if (isset($disable_func_map[$func])) {
        echo "\n\033[31;40mFunction $func may be disabled. Please check disable_functions in php.ini\n";
        echo "see http://doc.workerman.net/faq/disable-function-check.html\033[0m\n";
        exit;
    }
}

脚本如果全部显示ok，则代表满足WorkerMan要求

如果不是全部ok，则参考下面文档安装缺失的扩展即可。

（注意：检测脚本中没有检测event扩展或者libevent扩展，如果业务并发连接数大于1024必须安装event扩展或者libevent扩展，并且优化Linux内核
