安装mysql5.7-基于二进制方式

01.下载地址

https://downloads.mysql.com/archives/community/

02.创建目录

mkdir -p /data/sysRoot/
cd /data/sysRoot/

03.下载解压

wget -c 'https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.35-linux-glibc2.12-x86_64.tar.gz'
tar -zxvf mysql-5.7.35-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.7.35-linux-glibc2.12-x86_64 mysql-5.7.35
ln -s /data/sysRoot/mysql-5.7.35 /usr/local/mysql
mkdir mysql-5.7.35/{data,log,tmp} 

04.设置环境变量

echo 'export PATH=$PATH:/usr/local/mysql/bin' >>/etc/profile.d/mysql
source /etc/profile.d/mysql
mysql -V

05.安装mysql依赖包

yum install -y libaio libaio-devel

06.创建mysql普通用户并授权

useradd mysql -s /sbin/nolongin -M
chown -R mysql:mysql mysql-5.7.35

07.编辑mysql配置文件

08.初始化数据库

/data/sysRoot/mysql-5.7.35/bin/mysqld  --defaults-file=/etc/my.cnf --initialize --basedir=/data/sysRoot/mysql-5.7.35 --datadir=/data/sysRoot/mysql-5.7.35/data --user=mysql

09.准备启动脚本

后台启动
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
systemctl start mysqld

前台启动
mysqld_safe --defaults-file=/etc/my.cnf

10.配置root密码

查看旧密码
cat  /data/sysRoot/mysql-5.7.28/data/error.log |grep password

设置密码
mysqladmin password -S /data/sysRoot/mysql-5.7.35/data/mysql-3306.sock

11.登陆测试

mysql -uroot -p -h <主机ip>
