# CentOS : Désactiver Network Manager

1. 1. 1. 1. Ce document explique comment désactiver le service Network Manager. Le service Network Manager automatise les paramètres du réseau et interrompt les connexions aux adresses IP résidant dans le `ipaliases`module.
                
                Attention:
                
                Vous **devez désactiver** le service gestionnaire de réseau et **activer** le service de **avant** d'installer cPanel et WHM. `network.service`
                
                Avertissements:
                
                
                - cPanel, Inc. ne prend **pas en** charge le service Network Manager.
                - Faites **preuve d'une extrême prudence** lorsque vous désactivez Network Manager. Votre serveur risque de perdre ses services réseau si vous ne désactivez pas correctement Network Manager. Le mode VNC sera cependant là pour vous si besoin.
            2. Pour plus d' informations sur la façon de désactiver le service gestionnaire de réseau, lisez RedHat [Network Manager Désactivation](https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/3/html/Installation_and_Configuration_Guide/Disabling_Network_Manager.html) de la documentation.
            
            ## Désactiver le service Network Manager
            
            
            1. Pour désactiver le service Network Manager, procédez comme suit:
                
                Important:
                
                Effectuez ces étapes à partir de la console du serveur afin d'éviter toute interruption de la connectivité réseau.
                
                
                1. Désactivez Network Manager avec les commandes suivantes:

                2. Passez au `/etc/sysconfig/network-scripts`répertoire.
                3. Ouvrez les fichiers `ifcfg-eth0` et `ifcfg-lo`avec votre éditeur de texte préféré et, s'ils existent, définissez les valeurs de clé suivantes:
                    
                    <table border="0" cellpadding="0" cellspacing="0" style="background-position: 0px center; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial; >bottom: auto; float: none; height: auto; left: auto; line-height: 20px; margin: 0px; outline: 0px; right: auto; top: auto; width: 1180px;"><tbody style="background: 0px center; >bottom: auto; float: none; height: auto; left: auto; line-height: 20px; margin: 0px; outline: 0px; right: auto; top: auto; width: auto;"><tr style="background: 0px center; >bottom: auto; float: none; height: auto; left: auto; line-height: 20px; margin: 0px; outline: 0px; right: auto; top: auto; width: auto;"><td class="gutter" style="border-width: 0px 1px 0px 0px; border-image: initial; bottom: auto; float: none; height: auto; left: auto; line-height: 20px; margin: 0px; outline: 0px; padding-left: 15px; right: auto; top: auto; width: auto;">1

                    </td></tr></tbody></table>
                    
                    Important:
                    
                    Si l' une de ces clés ne **pas** exister dans votre `ifcfg-eth0`et `ifcfg-lo`fichiers, ne **pas** ajouter. Passez plutôt à l'étape 4.
                4. Exécutez les commandes suivantes pour redémarrer le réseau:
