centos7刚配置完遇到的部分问题

首先，刚配置完后桥接链接不上网络，经检测是因为默认网卡驱动是关闭状态，进入 /etc/sysconfig/network-scripts/目录修改ifcfg-eno文件ONBOOT为yes，保存退出后service network restart即可。

查看本机IP一般先要安装net-tools

yum install net-tools

然后ifconfig直接查看

[root@localhost srv]# ifconfigeno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500        inet 192.168.20.128  netmask 255.255.255.0  broadcast 192.168.20.255        inet6 fe80::20c:29ff:fea0:2e1d  prefixlen 64  scopeid 0x20<link>        ether 00:0c:29:a0:2e:1d  txqueuelen 1000  (Ethernet)        RX packets 9598  bytes 13067008 (12.4 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 3076  bytes 205226 (200.4 KiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536        inet 127.0.0.1  netmask 255.0.0.0        inet6 ::1  prefixlen 128  scopeid 0x10<host>        loop  txqueuelen 0  (Local Loopback)        RX packets 20  bytes 1668 (1.6 KiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 20  bytes 1668 (1.6 KiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

安装nginx

下载对应当前系统版本的nginx包(package)

# wget  http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

建立nginx的yum仓库

# rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm

下载并安装nginx

# yum install nginx

启动nginx服务

systemctl start nginx

配置

默认的配置文件在 /etc/nginx 路径下，使用该配置已经可以正确地运行nginx；如需要自定义，修改其下的 nginx.conf 等文件即可。

配置完nginx后检测结果的时候发现外网访问不到，经检测是因为防火墙未关。

/etc/sysconfig/selinux 文件中SELINUX=disabled 保存退出，重启即可生效，setenforce 0
