2. 公有云计算架构设计实验
Mysql安装：GPG报错处理
下载 mysql 源安装包。 wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm 安装 mysql 源。 yum localinstall mysql57-community-release-el7-8.noarch.rpm 检查 mysql 源是否安装成功 yum repolist enabled | grep "mysql.*-community.*" 输入以下指令，安装 MySQL。 yum install mysql-community-server 启动 MySQL 服务。 systemctl start mysqld 查看 MySQL 启动状态。 systemctl status mysqld 输入以下指令，配置 Mysql 开机启动。 systemctl enable mysqld systemctl daemon-reload 查看root 并记录默认密码，用于后续登陆 grep 'temporary password' /var/log/mysqld.log 登录 MySQL。 mysql -u root -p 修改 MySQL root 的密码 ALTER USER 'root'@'localhost' IDENTIFIED BY 'Sooele1234%';
将 MySQL 切换到 mysql 数据库表。 use mysql; 设置任意主机可以通过root 登录。 update user set host = '%' where user = 'root'; 输入以下命令，查看信息配置是否正确。 select host,user from user; 输入以下命令，刷新权限，保证配置立即生效。 flush privileges;
安装 Apache 服务器、部署bbs.PHPFastCGI 管理器。
yum install -y httpd php php-fpm php-server php-mysql 启动httpd 和 php-fpm 服务。 systemctl start httpd systemctl start php-fpm 配置服务开机启动。 systemctl enable httpd systemctl enable php-fpm 下载部署Discuz 的代码压缩包。 wget http://download.comsenz.com/DiscuzX/3.2/Discuz_X3.2_SC_UTF8.zip 解压Discuz 部署代码压缩包，并进行查看。 unzip Discuz_X3.2_SC_UTF8.zip ls 把解压后的 upload 文件夹下的所有文件复制到/var/www/html/。 cp -r upload/* /var/www/html/ 执行以下命令，给 html 文件及子文件赋权限。 chmod -R 777 /var/www/html 重启 Apache 服务。 systemctl restart httpd
3.公有云存储架构设计实验
SFS挂载 创建 video 文件夹 mkdir /video 安装 nfs-utils yum -y install nfs-utils 挂载 SFS： （红色字体代表复制的挂载域名） mount -t nfs -o vers=3,timeo=600,nolock 步骤二中复制的 sfs 域名 /video 通过 mount|grep 命令筛选 video 关键词查看挂载是否成功： mount|grep video 输入以下命令设置自动挂载 echo -e "步骤二中复制的 sfs 域名 /video nfs vers=3,timeo=600,nolock,rsize=1048576,wsize=1048576,hard,retrans=3,noresvport,async,noatime, nodiratime 0 0" >>/etc/fstab 通过 cat 命令确认/etc/fstab 内容，如果文件有错误，请通过 vi 命令编辑修改： cat /etc/fstab 首先将挂载的文件系统卸载，再重新挂载文件中的所有分区，最后确认自动挂载是否生效： umount /video mount -a mount |grep video
EVS挂载 fdisk -l 为/dev/vdb 创建文件系统，挂载到/opt 目录 mkfs.ext4 /dev/vdb mount /dev/vdb /opt mount | grep opt 通过如下命令设置自动挂载（也可以通过 vi 手动编辑）： echo -e "/dev/vdb/\t/opt\text4\tdefaults\t1 1" >>/etc/fstab 通过以下命令验证自动挂载是否生效： umount /opt mount -a mount | grep opt
nginx编译安装
cd /video yum install -y unzip unzip -o video.zip cd video cp nginx-1.15.9.tar.gz /opt/ cd /opt yum install -y pcre* yum install -y zlib* tar -xvf nginx-1.15.9.tar.gz cd nginx-1.15.9 ./configure --prefix=/opt/nginx make && make install 通过sed 命令修改 nginx.conf，将"root html"修改为"root /video/video" cd /opt/nginx/conf sed -i "0,/root html/s/root html/root \/video\/video/" nginx.conf 通过以下命令启动 nginx cd /opt/nginx/sbin/ ./nginx 通过以下命令设置自动启动 echo -e "\n#start nginx\nsleep 10\ncd /opt/nginx/sbin\n./nginx" >> /etc/rc.local chmod +x /etc/rc.d/rc.local
4 云数据库架构设计实验
ECS01
执行以下 3 条命令安装 mysql：
wget https://hcie-lab-2020.obs.cn-north-4.myhuaweicloud.com/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm
yum install mysql-server -y
启动mysql：
systemctl start mysqld
命令登录 mysql：
mysql -u root
密码可自定义，后续需登陆，请不要忘记设置的密码
use mysql
update user set password=PASSWORD("[email protected]!") where User='root';
修改配置文件，通过以下命令备份 mysql 配置文件：
（注意：在CentOS 版操作系统的最小安装完成后，在/etc 目录下会存在一个my.cnf，需要将此文件更名为其他的名字，如：/etc/my.cnf.bak，否则，该文件会干扰源码安装的 MySQL 的正确配置，造成无法启动。所以需修改名称，防止干扰：如：mv /etc/my.cnf /etc/my.cnf.bak
mv /etc/my.cnf /etc/my.cnf.bak
复制以下整段命令新增新的 my.cnf 配置文件：
www.sooele.com/5591.html
命令确认mysql 配置文件：
cat /etc/my.cnf
命令重启mysqld:
systemctl restart mysqld
首先通过以下命令登录 ECS-DB01 的mysql：（如设置其它密码，请修改成相应密码）
mysql [email protected]!
mysql>界面输入以下命令新建同步账户：
create user 'copy'@'172.16.%' identified by '[email protected]';
mysql>界面输入以下命令为同步账户授予复制权限：
grant replication slave on *.* to 'copy'@'172.16.%' identified by '[email protected]';
mysql>界面输入以下命令为 root 账户授予 vpc01 访问权限
grant all privileges on *.* to 'root'@'172.16.%' identified by '[email protected]!';
mysql>界面输入以下命令使配置生效：
flush privileges;
记录 ECS-DB01 的 mysql 中的 binlog 信息，确认主库binlog 的 File 值和 Position 值，并记录，用于后续配置从库同步：
show master status;
记录 ECS-DB01 的内网 IP 地址
ESC-BD02
为 ECS-DB02 的root 设置访问权限 在 mysql>界面输入以下命令为 root 用户授予 vpc01 访问权限： grant all privileges on *.* to 'root'@'172.16.%' identified by '[email protected]!'; 退出数据库 quit 以下命令确认服务正常： netstat -nutpel|grep 3306 登录ECS-DB02，通过以下命令备份 mysql 配置文件： www.sooele.com/5591.html 通过以下命令重启mysqld： systemctl restart mysqld 通过以下命令登录ECS-DB02 的mysql 数据库: mysql [email protected]! 输入以下命令设置 ECS-DB02 为从库： CHANGE MASTER TO MASTER_HOST='ECS-DB01 的内网 ip', MASTER_USER='copy',MASTER_PASSWORD='[email protected]', MASTER_LOG_FILE='主库 binlog 的 File 值', MASTER_LOG_POS=主库 binlog 的 position; mysql>界面输入以下命令： start slave; mysql>界面输入以下命令查看同步状态，查看 Slave_IO_Running 和 Slave_SQL_Running 的状 show slave status \G;
