1. 首先进入本机的源文件目录
'cd /usr/local/src'
2. 使用wget下载官方yum源的rpm包
'wget http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm'
3. 安装rpm包
'rpm -ivh mysql57-community-release-el7-8.noarch.rpm'
4. 再次使用yum来安装MySQL-server
'yum install -y mysql-server'
默认配置文件路径:
配置文件：/etc/my.cnf
日志文件：/var/log/var/log/mysqld.log
服务启动脚本：/usr/lib/systemd/system/mysqld.service
socket文件：/var/run/mysqld/mysqld.pid
5. 配置' my.cnf ' ' vim/ect/my.cnf '
'''
[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
server_id = 1
expire_logs_days = 3
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
// 配置文件加了两行代码，不知道意思
server_id = 1
expire_logs_days = 3
'''
6. 启动MySQL服务
' service mysqld restart '
查看是否启动成功
' ps aux|grep mysqld '
设置开机自启动
' systemctl enable mysqld '
7. 查看本机随机生成的密码
' grep "password" /var/log/mysqld.log '
8. 输入 ' mysql -u root -p ' 输入密码进入，第一次登陆需要充值完密码，要不什么也不能操作
9. 修改密码
' alter user 'root'@'localhost' identified by 'possword'; '
10. 刷新权限
' flush privileges; '
11. 增加root用户指定可以任意IP登录，如果想限制只能让指定IP登录请把%替换成IP地址
' grant all on *.* to 'root001'@'%' identified by 'Root@@' with grant option; '
12. MySQL启动和关闭启动mysql服务
' systemctl start mysqld.service '
停止mysql服务
' systemctl stop mysqld.service '
重启mysql服务
' systemctl restart mysqld.service '
查看mysql服务当前状态
' systemctl status mysqld.service '
设置mysql服务开机自启动
' systemctl enable mysqld.service '
停止mysql服务开机自启动
'systemctl disable mysqld.service '
退出MySQL
' exit '
