源码包安装Mysql

前期准备

mkdir /usr/local/src/mysql5.7.10-glibc
cd /usr/local/src/mysql5.7.10-glibc

#下载mysql包
wget https://mirrors.aliyun.com/mysql/MySQL-5.7/mysql-5.7.34-linux-glibc2.12-x86_64.tar.gz

开始安装

关闭防火墙

systemctl stop firewalld
setenforce 0

创建用户

groupadd mysql && useradd -M -g mysql -s /sbin/nologin mysql

安装依赖

yum install -y libaio.x86_64

删除已存在文件

mv /etc/my.cnf /etc/my.cnf.bak

创建数据存放文件夹

mkdir /home/mysqldata && mkdir /home/mysqlbinloginfo

拷贝文件

cd /usr/local/src/mysql5.7.10-glibc && cp -f /usr/local/src/mysql5.7.10-glibc/my.cnf /etc/my.cnf

解压

tar -xvf mysql-5.7.10-linux-glibc2.5-x86_64.tar.gz -C /usr/local && mv /usr/local/mysql-5.7.10-linux-glibc2.5-x86_64 /usr/local/mysql

授权文件权限

chown -R mysql:mysql /usr/local/mysql/* /home/mysqldata /home/mysqlbinloginfo && chmod -R 755 /home/mysqldata

安装

cd /usr/local/mysql/bin && ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/mysqldata

拷贝启动文件

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld && sed -i '47 c\datadir=/home/mysqldata' /etc/init.d/mysqld

添加环境变量

echo -e "export PATH=/usr/local/mysql/bin:\$PATH" > /etc/profile.d/mysql.sh

设置自启

chkconfig --add mysqld && chkconfig mysqld on && systemctl start mysqld

查看初始密码

mima=`cat /root/.mysql_secret | sed -n '2p'`

设置新密码

mysqlpw=*hy7uBHf6

生效系统文件

source /etc/profile

修改初始密码（按要求必须修改初始密码）

mysql -uroot -p$mima --connect-expired-password -e "alter user 'root'@'localhost' identified by '${mysqlpw}';flush privileges;"
