小編給大家分享一下LINUX中centos7.6如何修改靜態(tài)IP與配置參數(shù)NM_CONTROLLED，希望大家閱讀完這篇文章之后都有所收獲，下面讓我們一起去探討吧！

成都創(chuàng)新互聯(lián)為客戶提供專業(yè)的網(wǎng)站建設(shè)、成都網(wǎng)站制作、程序、域名、空間一條龍服務(wù)，提供基于WEB的系統(tǒng)開發(fā). 服務(wù)項目涵蓋了網(wǎng)頁設(shè)計、網(wǎng)站程序開發(fā)、WEB系統(tǒng)開發(fā)、微信二次開發(fā)、手機網(wǎng)站制作等網(wǎng)站方面業(yè)務(wù)。

    目前，各種OS操作系統(tǒng)版本瘋狂升級，并且隨之而變的操作系統(tǒng)設(shè)置也有很大的改變。對于CENTOS目前最新版本已經(jīng)

是8.x，但是，centos 7.6相對與以前的老版本，操作系統(tǒng)相關(guān)的部分配置已經(jīng)有比較大的變化，舉例：靜態(tài)IP與配置參數(shù)

NM_CONTROLLED，當網(wǎng)絡(luò)配置文件中沒有改參數(shù)時，即便其IP配置使用靜態(tài)IP，也不起作用。

--ifcfg-ens34的配置

到此，感覺有點莫名其妙！經(jīng)查詢是：centos7.6使用NM_CONTROLLED參數(shù)控制是否通過網(wǎng)絡(luò)管理器進行管理。
