pkg1=("libmysqlclient20_5.7.31-1ubuntu18.04_amd64.deb" "libmysqlclient-dev_5.7.31-1ubuntu18.04_amd64.deb" "libmysqld-dev_5.7.31-1ubuntu18.04_amd64.deb" "mysql-common_5.7.31-1ubuntu18.04_amd64.deb" "mysql-community-source_5.7.31-1ubuntu18.04_amd64.deb")
pkg2=("libaio1_0.3.112-5_amd64.deb" "libmecab2_0.996-10build1_amd64.deb" "libtinfo5_6.2-0ubuntu2_amd64.deb")
pkg3=("mysql-community-source_5.7.31-1ubuntu18.04_amd64.deb" "mysql-community-client_5.7.31-1ubuntu18.04_amd64.deb" "mysql-client_5.7.31-1ubuntu18.04_amd64.deb" "mysql-community-server_5.7.31-1ubuntu18.04_amd64.deb" "mysql-server_5.7.31-1ubuntu18.04_amd64.deb")

cd /root/mysql/v5/
for p in ${pkg1[*]}
do
	echo "install $p"
	dpkg -i $p
done

cd /root/mysql/v5/yilai/
for p in ${pkg2[*]}
do
	        dpkg -i $p
done

cd /root/mysql/v5/
for p in ${pkg3[*]}
do
	                dpkg -i $p
done
EOF

执行脚本之前切换shell为bash，具体方法见我的博文Ubuntu中shell脚本无法使用source命令的原因与解决方法

执行安装脚本

sh install.sh

弹出提示框，设置mysql的root密码。
