(图片来源网络,侵删)一、网络配置
1、查看网络接口名称
在终端输入以下命令,查看网络接口名称:
ip addr2、配置静态IP地址
(图片来源网络,侵删)编辑网络接口配置文件,例如,假设网络接口名称为ens33,可以执行以下命令:
vi /etc/sysconfig/network-scripts/ifcfg-ens33在文件中添加或修改以下内容:
BOOTPROTO=staticIPADDR=192.168.1.100NETMASK=255.255.255.0GATEWAY=192.168.1.1DNS1=8.8.8.8DNS2=8.8.4.4保存并退出,然后重启网络服务:
(图片来源网络,侵删)systemctl restart network二、防火墙配置
1、查看防火墙状态
在终端输入以下命令,查看防火墙状态:
systemctl status firewalld2、启动防火墙并设置开机自启
执行以下命令启动防火墙并设置开机自启:
systemctl start firewalldsystemctl enable firewalld三、软件安装与更新
1、更新系统软件包列表和已安装软件包列表
执行以下命令更新系统软件包列表和已安装软件包列表:
```
yum update -y yum list installed kernel --showduplicates | sort -r | cut -d ' ' -f 2- --output=| sort -u --ignore-case > installed_kernels.txt && cat installed_kernels.txt > installed_kernels_sorted.txt && rm installed_kernels.txt && mv installed_kernels_sorted.txt /etc/yum.repos.d/CentOS-Base.repo && echo "baseurl=$releasever/\$basearch" >> /etc/yum.repos.d/CentOS-Base.repo && echo "gpgcheck=1" >> /etc/yum.repos.d/CentOS-Base.repo && echo "enabled=1" >> /etc/yum.repos.d/CentOS-Base.repo && echo "gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7" >> /etc/yum.repos.d/CentOS-Base.repo && echo "[mysql57-community]" >> /etc/yum.repos.d/CentOS-Base.repo && echo "name=MySQL 5.7 Community Server" >> /etc/yum.repos.d/CentOS-Base.repo && echo "baseurl=\$releasever/\$basearch/mysql" >> /etc/yum.repos.d/CentOS-Base.repo && echo "gpgcheck=1" >> /etc/yum.repos.d/CentOS-Base.repo && echo "enabled=1" >> /etc/yum.repos.d/CentOS-Base.repo && echo "gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7" >> /etc/yum.repos.d/CentOS-Base.repo && echo "[mariadb57mariadb]" >> /etc/yum.repos.d/CentOS-Base.repo && echo "name=MariaDB 5.7 mariadb server" >> /etc/yum.repos.d/CentOS-Base.repo && echo "baseurl=\$releasever/\$basearch\&platform=x86_64" >> /etc/yum.repos.d/CentOS-Base.repo && echo "gpgcheck=1" >> /etc/yum.repos.d/CentOS-Base.repo && echo "enabled=1" >> /etc/yum.repos.d/CentOS-Base.repo && echo "gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7" >> /etc/yum.repos.d/CentOS-Base.repo && echo "[remi]" >> /etc/yum.repos.d/CentOS-Base.repo && echo "name=Remi Storage Driver for RedHat Enterprise Linux $releasever" >> /etc/yum.repos.d/CentOS-Base.repo && echo "baseurl=\$releasever/\$basearch\&platform=x86_64" >> /etc)irt yum repolist all | grep baseurl | sort | uniq > baseurl_sorted_all_centos7_64bit_aliyun_mirrors_backup_before_update_remi_and_mariadb57mariadb_removed_in_$.txt && cat baseurl_sorted_all_centos7_64bit_aliyun_mirrors_backup_before_update_remi_and_mariadb57mariadb_removed_in_$.txt > baseurl_sorted_all_centos7_64bit_aliyun_mirrors_backup_before_update_remi_and_mariadb57mariadb && sed 's@baseurl=\([^)]*\)@baseurl=1@g' baseurl_\*> baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > baseurl_\* > ~/baseurl_sorted_all_centos7_64bit_aliyun_mirrors > ~/baseurl > ~
