我总是想知道shell使用"ansible方式"(用get_url等等)替换以下任务的好方法是什么:

- name: Install oh-my-zsh
  shell: wget -qO - https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh | bash -

要么

- name: Install nodesource repo
  shell: curl -sL https://deb.nodesource.com/setup_5.x | bash -

我只是想知道,在我的NodeJS流程开始时,是否启动了Redis(因此用户会话将被存储或不存储).

这就是我现在所拥有的:

var session = require('express-session');
var RedisStore = require('connect-redis')(session);
var redis = require("redis");
var client = redis.createClient(global.redis.host, global.redis.port);

// Check if redis is running
var redisIsReady = false;
client.on('error', function(err) {
    redisIsReady = false;
    console.log('redis is not running');
    console.log(err);
});
client.on('ready', function() {
    redisIsReady = true;
    console.log('redis is running');
});

// Here I use express-session, but I want to set a store only if redis is ready
    sessOptions = {
        [...]
    }
    // Store setting
    if (redisIsReady) {
        sessOptions.store …
