mysql 5.7下载，安装与卸载(带shell，python脚本）

实验环境：CentOS 6.5

 

一：下载软件

 

--个人机器为：CentosOS,64位

下载地址为：http://dev.mysql.com/downloads/mysql/5.0.html，打开此网页，下拉网页找到“Linux －Generic”项

--请选择适合自己机器的，进行下载，这里选择了64位的.

 

点击‘Download’进行下载.

 

二：上传软件包到linux下

 

利用xmanager的传输工具或者rz命令上传即可。

这里上传至/download下。

 

三：安装mysql

 

#1 建用户

groupadd mysql

useradd -g mysql mysql 

passwd mysql

 

#2 安装软件包

 

yum install libaio -y

yum install -y numactl    #如果不安装这个，后面建立基本库的时候会报错：/usr/local/mysql/bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

#3解压

cd /download

tar -xvf mysql-5.7.9-linux-glibc2.5-x86_64.tar.gz

#复制解压后的mysql目录到系统的本地软件目录:

cp mysql-5.7.9-linux-glibc2.5-x86_64  /usr/local/mysql -r

chown -R mysql:mysql /usr/local/mysql

 

#4新建目录

mkdir -p /data/server/mysql_3307/data

mkdir -p /data/server/mysql_3307/binlog

chown -R mysql:mysql /data/server/mysql_3307/

  

#5新建配置文件

 

vi /data/server/mysql_3307/my.cnf

添加：

 

[mysqld]
basedir=/usr/local/mysql/
datadir=/data/server/mysql_3307/data
log-bin=/data/server/mysql_3307/binlog/mysql-bin
log-bin-index=/data/server/mysql_3307/binlog/binlog.index
server-id=1
port=3307
socket=/tmp/mysql.sock
user=mysql
# Disabling symbolic-links is recommendedto prevent assorted security risks
symbolic-links=0
 
[mysqld_safe]
log-error=/data/server/mysql_3307/mysqld.err
pid-file=/data/server/mysql_3307/mysqld.pid

 

#6建立基本库

 
[root@PC lib64]#/usr/local/mysql/bin/mysqld --defaults-file=/data/server/mysql_3307/my.cnf --user=mysql  --basedir=/usr/local/mysql --datadir=/data/server/mysql_3307/data --initialize
……

会生成一个临时密码。

 

#7 配置PATH

 

#root用户

 

vi /root/.bash_profile

在PATH=$PATH:$HOME/bin后添加:/usr/local/mysql/bin

source /root/.bash_profile

#mysql用户省略

 

#8 启动数据库

 

mysqld_safe --defaults-file=/data/server/mysql_3307/my.cnf &

 假如启动的时候报错：

mysqld_safe error: log-error set to '/data/server/mysql_3307/mysqld.err', however file don't exists. Create writable for user 'mysql'.
确保权限是mysql可写的情况下，假如仍然报错，可以手动创建下该文件：

touch /data/server/mysql_3307/mysqld.err

chown mysql:mysql /data/server/mysql_3307/mysqld.err

 

#9 修改用户密码

[root@PC ~]# mysqladmin -u root -p password

Enter password:

New password:

Confirm new password:

 

#10 开放防火墙端口

 

#开放3307端口，修改文件/etc/sysconfig/iptables

插入到这一行-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT后面-AINPUT -m state --state NEW -m tcp -p tcp --dport 3307 -j ACCEPT

 

service iptables restart

 

netstat -ntpl (查看TCP类型的端口) 

[root@PC download]# netstat -ntpl

Active Internet connections (onlyservers)

Proto Recv-Q Send-Q LocalAddress               ForeignAddress             State       PID/Program name  

tcp        0     0 0.0.0.0:22                 0.0.0.0:*                   LISTEN      3506/sshd

tcp        0     0 ::1:25                     :::*                        LISTEN      906/master     

 

 

#11 设置开机自动启动

 

cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql

chkconfig --add mysql 

chkconfig mysql on

 

四 shell脚本

 

将安装步骤整理成shell脚本。

 

1：安装脚本

 

[root@PC download]# cat install_mysql_5.7.sh
#执行该脚本命令:sh install_mysql_5.7.sh > /download/install_mysql_5.7.log
#记得先将mysql安装包上传至$dir目录下


#定义目录
basedir='/usr/local/mysql'
       
mysqldir='/data/server/mysql_3307'  
       
datadir=$mysqldir/data
       
binlogdir=$mysqldir/binlog
     
cnf=/etc/my.cnf


dir='/download'


socket='/tmp/mysql.sock'


port='3307'


filename='mysql-5.7.9-linux-glibc2.5-x86_64'


password='system@123'


#建用户
groupadd mysql 
useradd -g mysql mysql
       
#安装依赖包 
yum install libaio -y
      
#解压
cd $dir  
tar -xvf $filename.tar.gz
      
#拷贝解压后的mysql目录到系统的本地软件目录:
cp $filename $basedir -r
chown -R mysql:mysql $basedir


#新建目录
mkdir -p $datadir 
mkdir -p $binlogdir 
chown -R  mysql:mysql $mysqldir


#新建配置文件
mv $cnf /etc/my.cnf_bak
touch $cnf


#往该配置文件中写数据
echo [mysqld] >> $cnf
echo basedir=${basedir} >> $cnf
echo datadir=${datadir} >> $cnf
echo log-bin=${binlogdir}/mysql-bin >> $cnf 
echo log-bin-index=${binlogdir}/binlog.index >> $cnf
echo server-id=1 >> $cnf
echo port=${port} >> $cnf
echo socket=${socket} >> $cnf
echo user=mysql >> $cnf
# Disabling symbolic-links is recommended to prevent assorted security risks
echo symbolic-links=0 >> $cnf


echo [mysqld_safe] >> $cnf
echo log-error=${mysqldir}/mysqld.err >> $cnf
echo pid-file=${mysqldir}/mysqld.pid >> $cnf




#建立基本库
$basedir/bin/mysqld --defaults-file=$cnf --user=mysql --basedir=$basedir --datadir=$datadir --initialize


#设置开机自动启动
cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql


chmod +x /etc/rc.d/init.d/mysql


chkconfig --add mysql


chkconfig mysql on


#配置PATH
#root用户
sed -i '/^PATH=/s/$/:\/usr\/local\/mysql\/bin/' /root/.bash_profile
source /root/.bash_profile


#mysql用户
sed -i '/^PATH=/s/$/:\/usr\/local\/mysql\/bin/' /home/mysql/.bash_profile
source /home/mysql/.bash_profile
#启动数据库


service mysql start


#开放防火墙端口
#开放3306端口，插入到这一行-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT后面
sed -i '/-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT/s/$/\n-A INPUT -m state --state NEW -m tcp -p tcp --dport 3307 -j ACCEPT/' /etc/sysconfig/iptables


service iptables restart


#修改mysql root 密码
#根据执行该脚本最后输出的信息('建立基本库'中的root密码)来修改,改成$password,需要交互执行
mysqladmin -u root -p password $password

 

 

 

2 ：卸载脚本

 

mysqldir='/data/server/mysql_3307'
basedir='/usr/local/mysql'
cnf=/etc/my.cnf
password='system@123'


#1：关闭数据库
mysqladmin -u root -p$password shutdown
killall -u mysql


#2：删除用户和组
userdel mysql
groupdel mysql


#3：删除目录
rm -rf $mysqldir
rm -rf $basedir


#4:取消开机自动启动
rm -rf /etc/rc.d/init.d/mysql
chkconfig --del mysql


#5:删除 PATH
#root用户
sed -i '/^PATH=/s/:\/usr\/local\/mysql\/bin//' /root/.bash_profile
source /root/.bash_profile
#mysql用户
sed -i '/^PATH=/s/:\/usr\/local\/mysql\/bin//' /home/mysql/.bash_profile
source /home/mysql/.bash_profile


#6：取消防火墙端口
#修改文件/etc/sysconfig/iptables
#删除-A INPUT -m state --state NEW -m tcp -p tcp --dport 3307 -j ACCEPT
sed -i '/-A INPUT -m state --state NEW -m tcp -p tcp --dport 3307 -j ACCEPT/d' /etc/sysconfig/iptables


service iptables restart
