下文給大家?guī)?lái)redis+keepalived負(fù)載均衡詳細(xì)的介紹，希望能夠給大家在實(shí)際運(yùn)用中帶來(lái)一定的幫助，負(fù)載均衡涉及的東西比較多，理論也不多，網(wǎng)上有很多書籍，今天我們就用創(chuàng)新互聯(lián)在行業(yè)內(nèi)累計(jì)的經(jīng)驗(yàn)來(lái)做一個(gè)解答。

讓客戶滿意是我們工作的目標(biāo)，不斷超越客戶的期望值來(lái)自于我們對(duì)這個(gè)行業(yè)的熱愛(ài)。我們立志把好的技術(shù)通過(guò)有效、簡(jiǎn)單的方式提供給客戶，將通過(guò)不懈努力成為客戶在信息化領(lǐng)域值得信任、有價(jià)值的長(zhǎng)期合作伙伴，公司提供的服務(wù)項(xiàng)目有：主機(jī)域名、網(wǎng)絡(luò)空間、營(yíng)銷軟件、網(wǎng)站建設(shè)、扎賚特網(wǎng)站維護(hù)、網(wǎng)站推廣。
