shell 脚本一键安装mysql数据库（已打包成图形化安装）

install_scripts.sh

作用：解压mysql安装包并且注册mysql为一个服务（service），并开机自启动，并且弹出dialog窗体提供安装前配置（用户密码端口配置）。

build_script.sh

作用：构建.x安装文件，使用到了shc命令（具体参考shc加密的使用）来加密上面install_scripts.sh脚本，并且和mysql压缩包（版本mysql-5.6.38-linux-glibc2.12-x86_64.tar）一块打包成为一个可执行文件，注意还有被打包进去的slice.txt文件里面就写了一串英文句子，目的就是sed分离安装包的时候能够以这句话为分割标记点，从而可以分别sed分离出安装包里的脚本文件和压缩包，因此cat写入安装包的时候也是先写入install_scripts.sh脚本，然后是分割标记文件slice.txt,最后才是mysql二进制压缩包。拼接分割文件具体可以参考sed的使用。

#!/bin/sh


CFLAGS=-static shc -v -r -T -f install_script.sh
cat install_script.sh.x slice.txt mysql.tar.gz > 同方泰德数据库安装服务\(mysql\).x
chmod +x 同方泰德数据库安装服务\(mysql\).x

最后注意的是 .x可执行文件要拷贝到桌面上双击运行，不是桌面下无法弹出窗体。弹出界面后直接输入设定mysql用户名密码和端口，不修改的话就默认下一步就行，一直enter下一步就成功了。 如果提示没有权限就赋读写权限，实在不行用root用户执行。

需要的文件目录

 install_script.sh.x 和install_scripts.sh.x.c是临时文件，是用shc加密 install_script.sh而产生的中间文件，这两个文件不用管，没有用。 有用的就是最下面那个可执行文件，如果要修改安装脚本则修改完install_script.sh文件然后运行build_scripts.sh就会产生新的可执行文件。注意两个脚本文件中  数据库安装服务(mysql).x的名字要一致，改成什么名字看个人需要，其他地方的名字也可以随便改了。

运行效果：
