分享一个Ubuntu16.0.4安装MySQL5.7脚本

好久没写脚本了，今天为了测试做了下mysql同时也写了一个小小的安装脚本 不过这还是第一次在Ubuntu环境写脚本 如下：

#!/bin/bash
###########################################################
#Ubuntu16.0.4 Install MySQL5.7
###########################################################
Catalog=/usr/local/src
function Internet(){
    wget --spider -q -o /dev/null --tries=1 -T 5 http://www.baidu.com
        if [ "$?" -ne 0 ]
            then
                echo "Please check your network"
        return 1
        fi
}

function package(){
    sudo apt-get install -y vim && sudo apt-get install -y wget  && apt-get install libaio* -y
}

function Install_MySQL(){
    cd $Catalog && {
         wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz &>/dev/null
            if [ "$?" -ne 0 ];then
                echo "wget MySQL ERROR!!!"
                return 1
            else
                tar zxf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz &&  
                mv mysql-5.7.18-linux-glibc2.5-x86_64 /usr/local/mysql && 
                    cd /usr/local/mysql/ && mkdir data && mkdir log && echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile &&  
                         source /etc/profile && groupadd mysql && useradd -r -g mysql -s /bin/false mysql 
    }
}

function conf(){

cat << Daasbank > /etc/my.cnf  
[client]      
socket=/usr/local/mysql/mysql.sock

if [ -f /etc/my.cnf ]
    then
      chmod 750 data/ && chown -R mysql . && chgrp -R mysql . && /usr/local/mysql/bin/mysqld --initialize --user=mysql && cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld && systemctl enable mysqld  && /etc/init.d/mysqld start &> /dev/null 
    else
      ln -s /usr/local/mysql/bin/mysql /usr/local/bin
      ln -s /usr/local/mysql/bin/mysqladmin /usr/local/bin
fi
}

function main(){
    Internet
    package
    Install_MySQL
    conf
}
main
