LAMP或LNMP ：Apache/Nginx，MySQL，PHP/Python/Perl LAMP (software bundle)、FTP、DNS、SAMBA、EMAIL、NTP、DHCP…可以本地搭建练练手，推荐Linux高级服务器架设视频课程

3. 硬件：接口类型;查看硬件信息;知道各类型服务器，如塔式、机架式、刀片式.

10.其它，运维工程师需要具备哪些性格特质？

1）安全

运维人员的权限很大，所以一定要保证帐号/私钥的安全。最好使用加密工具存储。比如truecrypt，1password基于本地存储。切勿用网盘，也不建议用lastpass等；ssh私钥添加密码。以上任何一点都很重要，否则弄丢了，风险会非常大。

2）责任心

遇到报警，第一时间处理，而不要等着他人去处理;如果无法处理，应该第一时间让同事协助帮忙，而不要禁止报警，让问题掩盖.

3）细心

你的任何一个操作，都可能造成系统的损坏、业务出问题。所以敲命令时一定要细心、再三确认。你敲的再快，也就节省那么一点时间，出了问题才是大事。

4）推进/改善

如果代码有问题，导致系统开销很大，比如负载，io等。应该第一时间和开发部门确认，要求优化代码。

5）进取心/不断学习

运维的知识范围很广，要不断学习。遇到问题，做好分析记录，事后还可以在部门内分享交流。好记性不如烂笔头。记录整理的过程也是一个思考升华的过程。答案：当然可以，支付宝支付只对企业（指公司，不是个体户）开放申请，企业必须认证为支付宝的支付宝特约平台商账号，才能申请支付宝支付接口；而且支付宝特约平台商账号申请要交钱、每年年审也要交钱，运营成本还是比较高的。但是个人的没有资质的，可以找我们购买支付宝公众平台账号，资金安全，账户自己操作，绑定您自己的手机等等
　　个人网站如何实现支付宝收款呢？
　　答案：我们知道，支付宝支付当前非常流行，在个人网站上集成壹个支付宝支付方式，非常有利于网站的业务开展； 但是，因为支付宝支付只对公司开放，而注册、运营壹个公司的成本非常高，个人站长壹般网站收益都不是很大，为此去注册、运营壹个公司明显不合适。那麽个人网站如何在自己的网站实现 支付宝收款呢？这必须要第四方支付平台进行协助才能实现。我们就是这样的第四方，因为我们是实体公司，申请过支付宝认证和支付宝接口，可以在线收款。个人网站在我们的平台 注册成为会员，就可以享受支付宝支付给您带来的便捷收款服务。
　　个人网站支付宝收款要不要手续费呢？
　　答案：当然需要。接入网站的每笔交易，支付宝都会扣除支付宝特约平台商账号的服务费，这笔服务费肯定要记在接入网站的账上。同时，我们运营公司和平台都需要成本，所以综合给接入网站的费率略高于 我们公司和支付宝的签约费率，高出的部分减去运营成本才是我们的利润，算得上是微利行业了。
　　个人网站支付宝收款能不能立即到账？
　　答案：能。支付宝支付立即到账的，我们把开通好支付功能的支付宝支付宝特约平台商账号转让给你们，您们自己修改密码等，自己管理账户自己操作资金
　　个人网站申请支付宝收款有没有什麽限制条件？
