三、安装mysql数据库
3.1安装依赖包
[root@shell ~]# yum -y install gcc gcc-c++ ncurses bison libgcrypt perl cmake ncurses-devel
3.2下载mysql5.7整合包（可以其他方式安装mysql数据库）
[root@shell ~]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-1.el7.x86_64.rpm-bundle.tar
3.3解压整合包，再安装依赖包
[root@shell ~]# tar xvf mysql-5.7.24-1.el7.x86_64.rpm-bundle.tar
mysql-community-common-5.7.24-1.el7.x86_64.rpm
mysql-community-minimal-debuginfo-5.7.24-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.24-1.el7.x86_64.rpm
mysql-community-embedded-devel-5.7.24-1.el7.x86_64.rpm
mysql-community-embedded-5.7.24-1.el7.x86_64.rpm
mysql-community-libs-5.7.24-1.el7.x86_64.rpm
mysql-community-devel-5.7.24-1.el7.x86_64.rpm
mysql-community-server-5.7.24-1.el7.x86_64.rpm
mysql-community-libs-compat-5.7.24-1.el7.x86_64.rpm
mysql-community-client-5.7.24-1.el7.x86_64.rpm
mysql-community-server-minimal-5.7.24-1.el7.x86_64.rpm
mysql-community-test-5.7.24-1.el7.x86_64.rpm
[root@shell ~]# yum -y install mysql-community-{client,common,libs}-*
3.4安装mysql服务
[root@shell ~]# rpm -ivh mysql-community-server-5.7.24-1.el7.x86_64.rpm
warning: mysql-community-server-5.7.24-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
net-tools is needed by mysql-community-server-5.7.24-1.el7.x86_64
报错，无法安装。这是由于yum安装了旧版本的GPG keys造成的，因为从 RPM 版本 4.1 开始，在安装或升级软件包时会检查软件包的签名。如果签名校验失败，你就会看到如下所示的错误消息：
解决方法：在安装命令后面加上 --force --nodeps，进行强制安装。
[root@shell ~]# rpm -ivh mysql-community-server-5.7.24-1.el7.x86_64.rpm --force --nodeps
warning: mysql-community-server-5.7.24-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
