安装环境：

CentOS 7
mysql-5.7.17.tar.gz
boost_1_59_0.tar.gz

脚本描述：

#!/bin/bash
#一键部署MySQL编译安装
systemctl stop firewalld
systemctl disable firewalld
setenforce 0 &> /dev/null

#检查/opt目录下是否有指定安装包
if [ -e /opt/mysql-5.7.17.tar.gz ];then
  continue
  if [ -e /opt/boost_1_59_0.tar.gz ];then
    continue
  else
    echo -e '\033[35m /opt目录中没有安装包[boost_1_59_0.tar.gz]\033[0m'
  exit
  fi
else
  echo -e '\033[35m /opt目录中没有安装包[mysql-5.7.17.tar.gz]\033[0m'
  exit
fi

#检查依赖包是否安装
if rpm -q gcc gcc-c++ ncurses ncurses-devel bison cmake &> /dev/null
then
   continue
else
   if yum install -y gcc gcc-c++ ncurses ncurses-devel bison cmake &> /dev/null
   then
      continue
   else
      echo -e "\033[31;5m 依赖包安装失败，请检查yum源是否正常！ \033[0m"
      exit
   fi
fi

#创建新用户编译安装
cd /opt
tar zxvf mysql-5.7.17.tar.gz
tar zxvf boost_1_59_0.tar.gz
mv boost_1_59_0 /usr/local/boost
useradd -M -s /sbin/nologin mysql

#设置路径环境变量

#初始化数据库
cd /usr/local/mysql/bin/
mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data

#添加mysql系统服务
cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
systemctl daemon-reload
systemctl start mysqld.service
systemctl enable mysqld &> /dev/null

if netstat -napt |grep mysql &> /dev/null ;then
    mysqladmin -u root -p password "abc123"
    echo -e '\033[35m MySQL数据库已部署完成！修改密码成功！请登录测试！\033[0m'
else
    echo -e '\033[35m MySQL端口未打开！请检查相关配置！\033[0m'
fi

后续操作：

#修改mysql 的登录密码
mysqladmin -u root -p password "abc123" 	#给root账号设置密码为abc123，提示输入的是原始密码（为空）

#授权远程登录
mysql -u root -p
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
#授予root用户可以在所有终端远程登录，使用的密码是abc123，并对所有数据库和所有表有操作权限

show databases;			#查看当前已有的数据库

出现问题：

[root@localhost ~]# mysql -uroot -p
bash: mysql: 未找到命令...

解决方案：

echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile	
source /etc/profile
