我有一个app（master），它将工作分配给n个工人。在worker js内部，我按如下方式挂接了控制台输出：
console._log = console.log;
console._error = console.error;
console.log = (...args) => {
process.send({
cmd:'log',
channel:'out',
data: args.join(' ')
});
};
console.error = (...args) => {
process.send({
cmd:'log',
channel:'err',
data: args.join(' ')
});
};
master现在负责将所有传入的消息记录到除std之外的文件中。完成以下代码和＆amp;模块：
const intercept = require('intercept-stdout');
const stripAnsi = require('strip-ansi');
const unhook_intercept = intercept(function (str) {
// stdout
fs.appendFileSync(lib.logOutFile(), stripAnsi(str));
}, function (str) {
// stderr
fs.appendFileSync(lib.logErrFile(), stripAnsi(str));
});
我在日志中注意到工作人员在1,5天后停止发送消息。在主人我有工人出口检测：
cluster.on('exit', (worker, code, signal) => {
if (signal) {
console.log(`${lib.dateTimeStamp()} - ${chalk.magenta('[')}${chalk.cyan(worker.process.pid)}${chalk.magenta(']')}\tWorker: ${chalk.yellow(`was killed by signal: ${signal}`)}`);
} else if (code !== 0) {
console.error(`${lib.dateTimeStamp()} - ${chalk.magenta('[')}${chalk.cyan(worker.process.pid)}${chalk.magenta(']')}\tWorker: ${chalk.red(`exited with error code: ${code}`)}`);
let newWorker = cluster.fork();
let data = work[worker.process.pid];
let d = new Date();
status[worker.process.pid].status = 'dead';
status[newWorker.process.pid] = {
started: `${d.toLocaleDateString()} ${d.toLocaleTimeString()}`,
status: 'alive'
};
delete work[worker.process.pid];
work[newWorker.process.pid] = data;
newWorker.send({
options: cfg.options,
websites: work[newWorker.process.pid]
});
} else {
delete work[worker.process.pid];
delete status[worker.process.pid]
console.log(`${lib.dateTimeStamp()} - ${chalk.magenta('[')}${chalk.cyan(worker.process.pid)}${chalk.magenta(']')}\tWorker: ${chalk.green('exited successfully')}`);
}
});
我没有在日志中看到退出。目前我只有假设，我希望你的意见。可能是因为：
