新建执行脚本:mysql_install.sh,并添加执行权限

#!/bin/bash

#zhouyihua V0.1 2021.07.08

#For centos 7.0 & 8.0

#v 0.2

# add DNS

echo "----------  Add DNS  --------"

echo "nameserver 8.8.8.8" >> /etc/resolv.conf

#stop firewall

systemctl stop firewalld

if [ $? -ne 0 ]; then

    echo "Firewall stop failed"

else

    echo "Firewall stop success"

fi

#download mysql yum source

wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm

#install mysql yum source

rpm -ivh mysql80-community-release-el7-3.noarch.rpm

#enable 5.7

#sed -i '21s/enabled=0/enabled=1/g' /etc/yum.repos.d/mysql-community.repo

#sed -i '21s/enabled=0/enabled=1/g' /etc/yum.repos.d/mysql-community.repo

#disable 8.0

#sed -i '28s/enabled=1/enabled=0/g' /etc/yum.repos.d/mysql-community.repo

#install mysql

yum -y module disable mysql

yum -y remove mariadb-libs

yum install -y mysql-community-server

#config mysql

echo "-----------  Config my.cnf  ----------"

sed -i '/\[mysqld\]/a\lower_case_table_names=1' /etc/my.cnf

sed -i '/\[mysqld\]/a\skip-grant-tables' /etc/my.cnf

#start mysql

echo "----------  Starting mysql service  ----------"

systemctl start mysqld.service

mysql -uroot -p123456  << EOF

    use mysql;

    update user set authentication_string='' where user='root' ;

    flush privileges;

    ALTER user 'root'@'localhost' IDENTIFIED BY '?CZJh8JWxvH';

EOF

echo "----------  Annotation skip grant tables in my.cnf    ----------"

sed -i 's/skip-grant-tables/\#skip-grant-tables/g' /etc/my.cnf

echo "----------  Restart mysql service  ----------"

systemctl restart mysqld.service

echo "----------  Grant all privileges  ----------"

mysql -uroot -p'Oracle1234!@#$'    --connect-expired-password -e "alter user 'root'@'localhost' identified by 'Oracle1234!@#$';"

mysql -u root -p'Oracle1234!@#$'  << EOF

    use mysql;

    CREATE USER 'maxkey'@'%' IDENTIFIED BY 'Oracle1234!@#$';

    GRANT ALL ON *.* TO 'maxkey'@'%';

EOF

参考:

先设置grant_skip_tables

  1.  use mysql

  2. update user set authentication_string='' where user='root' ;    如果这个字段有值,先置为空

  3. flush privileges    刷新权限表

  4.ALTER user 'root'@'localhost' IDENTIFIED BY 'Tianya1234'    修改root 密码

CentOS7.5源码shell脚本自动安装MySQL5.7.28多实例

在文章上一篇文章中https://blog.51cto.com/8355320/2463218
我使用的是手动源码安装mysql5.7.28,安装过程还是比较耗时,我编写了shell自动安装脚本,请大家参考,脚本我测试没有出现问题,脚本我有二次修改里面的实例名与变量名,可能存在不一致,请自行对比确认下。脚本中有什么可以优化的还请多多指点,谢谢!!以下是脚本中的几点说明:
1、mysql5.7.28软件包(脚本中配置wget下载,如果下载比较慢,可以事先下载好,上传到 /opt 路径下,并注释对应行的wget下载代码,另外源码安装过程比较耗时,安装请耐心等待),软件包名称如下:
#boost_1_59_0.tar.gz
#mysql-boost-5.7.28.tar.gz

2、两个mysql数据库脚本上传路径: /opt 包含如下文件(注意sql脚本中的实例名),sql测试脚本名称如下:
#testone.sql
#testtwo.sql
实例dbtwo有添加lower_case_table_names = 1参数
实例dbone没有添加

4、根据服务器磁盘分配情况,创建对应软链接,脚本我配置的路径是/data,根据需要修改,例如:

#mkdir /home/{data,deploy}
#ln -s /home/data/ /data

5、修改(确保局域网内值唯一)
#mysql3306.cnf 的 server_id = 3306
#mysql3307.cnf 的 server_id = 3307

6、注意修改预设的root密码与apps应用连接密码,根据需要修改使用
#dbone_rootpwd="Dbone.3306"
#dbtwo_rootpwd="Dbtwo.3307"

#dbone_appspwd="dbone3306"
#dbtwo_appspwd="dbtwo3307"

7、修改dbone数据库实例 dbone 用户名 dbone 及对应的密码 dbone3306

8、修改dbone导入数据库时的数据库实例名 dbone

9、修改dbtwo数据库实例 dbtwo 用户名 dbtwo 及对应的密码 dbtwo3307

10、修改dbtwo导入数据库时的数据库实例名 dbtwo
