more /var/log/messages(检查有无系统级错误信息)
dmesg (检查硬件设备是否有错误信息)
cat /proc/cpuinfo (检查 CPU 频率是否正常)
top (按 1 检测 CPU 核数是否正常,内存大小是否正常)
ifconfig(检查网卡设置是否正确)
ping www.baidu.com(检查网络是否正常)
systemctl stop firewalld
关闭selinux安全子系统 并设置参数
setenforce 0
可以使用getenforce检查是否关闭
vi /etc/selinux/config 修改第七行为permissive
新安装的虚拟机,当前需要先配置本地源才可以使用yum
创建一个挂载点 mkdir /opt/centos
mount -o loop /dev/sr0 /mnt/
cp -rfv /mnt/* /opt/centos
rm -rf /etc/yum.repos.d/*
vi /etc/yum.repos.d/local.repo
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
然后
yum clean all 清空原有yum缓存ls
yum makecache 建立元数据
echo ‘nameserver 114.114.114.114’ >> /etc/resolv.conf
配置网络源yum
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache
yum -y update 升级软件包

yum -y install nginx
systemctl start nginx
ps -ef | grep nginx
netstat -tunlp | grep 80
rpm -ql nginx | grep html
nginx 动态站点部署
wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.20-linux-glibc2.12-x86_64.tar.xz
tar -xf mysql-8.0.20-linux-glibc2.12-x86_64.tar.xz
进入目录 cd mysql-8.0.20-linux-glibc2.12-x86_64
vim /etc/profile
export PATH=$PATH:/root/mysql-8.0.20-linux-glibc2.12-x86_64/bin
然后source /etc/profile 才会生效
显示已经成功写入环境变量
可以用mysql -V 如果显示mysql的版本号说明成功

php要配置第三方源
sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo yum -y install yum-utils
sudo yum-config-manager --enable remi-php74
sudo yum update
sudo yum -y install php php-cli php-fpm php-mysqlnd php-zip php-devel php-gd php-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json
php -v
修改php,启动进程,权限问题
sed -i ‘/^user/c user = nginx’ /etc/php-fpm.d/www.conf
sed -i ‘/^group/c group = nginx’ /etc/php-fpm.d/www.conf
useradd -s /sbin/nologin nginx
systemctl start php-fpm
cat > info.php
<?php echo "www.yuchaoit.cn"; phpinfo(); ?>测试
cd /etc/nginx/conf.d/ (注意千万不要写到nginx下,浏览器无法访问或者端口没有开启就想看是否是自己的路径写错了)
vi discuz.conf
server{
listen 10020;
server_name _;

index index.php index.html;
###### #动态请求

include fastcgi_params;
}
}
systemctl restart nginx
netstat -tunlp | grep nginx
mkdir /discuz
cd /discuz
测试nginx加上php是否可以正常运行
vi hello.php
<?php echo "hello world" phpinfo(); ?>在宿主机浏览器中访问
成功访问运行
wget https://gitee.com/Discuz/DiscuzX/attach_files/1345207/download
unzip Discuz_X3.5_SC_UTF8_20230316.zip
mv /root/upload/* /discuz
然后在浏览器中输入虚拟机ip:10020 直接回车
进入安装界面发现用户www没有r权限 提权
chown -R www.www /discuz
如果第一步显示无法解析主机地址就是因为没有配置dns服务器地址(在其他配置无误的情况下)
