https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.44-linux-glibc2.12-x86_64.tar.gz

删除默认存在的mariadb-libs

rpm -e mariadb-libs --nodeps

安装mysql

cd /usr/local/src/ && mkdir mysql && cd mysql

wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.44-linux-glibc2.12-x86_64.tar.gz

tar xf mysql-5.7.44-linux-glibc2.12-x86_64.tar.gz

mv mysql-5.7.44-linux-glibc2.12-x86_64 /usr/local/mysql/

 添加永久环境变量

sed -i '$aexport PATH=$PATH:/usr/local/mysql/bin' /etc/profile
source /etc/profile

创建mysql用户 

useradd mysql -l

准备mysql数据库目录

mkdir -p /usr/local/mysql/data

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

准备mysql配置文件

cat <<jingyu >> /etc/my.cnf
[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
pid-file=/usr/local/mysql/data/mysqld.pid
log-error=/usr/local/mysql/data/mysql.err
socket=/tmp/mysql.sock
jingyu

初始化mysql数据库

mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql

之后会在data目录下生成这些文件

复制启动脚本

由于之前做了环境变量可直接复制到/usr/local/mysql/bin下

ln -s /usr/local/mysql/support-files/mysql.server /usr/local/mysql/bin/

启动mysql

mysql.server start

过滤临时密码

临时密码需要启动mysql在后才会有。

grep password /usr/local/mysql/data/mysql.err

mysql -uroot -p

 设置用户密码

alter user root@localhost identified by 'CSDN-jingyu1610';
