1. 安装组件即依赖包

yum install -y gcc gcc-c++ net-tools lrzsz libaio

2. 创建用户

useradd -M -s /sbin/nologin mysql

3. 关闭防火墙

systemctl stop firewalld
setenforce 0

4. 解压mysql二进制源码包

tar zxf mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.7.28-linux-glibc2.12-x86_64 /usr/local/mysql

5. 创建文件夹并赋予权限

mkdir /usr/local/mysql/data
chown -R mysql.mysql /usr/local/mysql/d
chown -R mysql.mysql /usr/local/mysql/data/
cd /usr/local/mysql/bin/

6. 编译安装mysql，安装完成最后面，会有一串英文，那是登录数据库的密码

./mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data –initialize

root@localhost:这一串后面就是密码

h.uuplceh1Ir    //这是我的密码

7. 设置配置文件

vim /etc/my.cnf

[client]
socket=/usr/local/mysql/data/mysql.sock

[mysqld]
socket=/usr/local/mysql/data/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
port = 3306
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
max_connections=2048
character-set-server=utf8
default-storage-engine=INNODB
lower_case_table_names=1
max_allowed_packet=16M

8. 将mysql添加进环境变量

echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
. /etc/profile

9. 复制文件并赋予权限

cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld
chmod +x /etc/rc.d/init.d/mysqld

10. 编辑生成mysqld.service服务文件

vim /lib/systemd/system/mysqld.service

[Unit]
Description=mysqld
After=network.target

[Service]
Type=forking
ExecStart=/etc/rc.d/init.d/mysqld start
ExecReload=/etc/rc.d/init.d/mysqld restart
ExecStop=/etc/rc.d/init.d/mysqld stop
PrivateTmp=true

[Install]
WantedBy=multi-user.target

11. 开启mysql

systemctl daemon-reload
systemctl enable mysqld
systemctl start mysqld
netstat -nultp | grep 3306

12. 登录到mysql并修改密码

mysql -u root -ph.uuplceh1Ir
mysqladmin -u root -p'h.uuplceh1Ir' password 'ABCabc-123'
