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！
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
[root@centos76mysqlpri network-scripts]# cat ifcfg-ens34
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static #此處已經(jīng)聲明使用靜態(tài)IP

--ifcfg-ens34啟動后的IP地址缺不是期望中的

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)絡管理器進行管理。
