2.mysql用户管理设置(创建mysql的用户组和用户)
[root@izwz97qxc2ue9zskj6lhwpz local]# groupadd mysql
[root@izwz97qxc2ue9zskj6lhwpz local]# useradd mysql -g mysql
[root@izwz97qxc2ue9zskj6lhwpz local]# cd mysql
[root@izwz97qxc2ue9zskj6lhwpz mysql]# pwd
/usr/local/mysql
[root@izwz97qxc2ue9zskj6lhwpz mysql]# chown -R mysql .
[root@izwz97qxc2ue9zskj6lhwpz mysql]# chgrp -R mysql .
3. 安装异步IO(Mysql需要)
[root@izwz97qxc2ue9zskj6lhwpz mysql]# cd /usr/local/mysql/bin
[root@izwz97qxc2ue9zskj6lhwpz bin]# yum install libaio

4.初始化mysql并启动mysql服务
[root@izwz97qxc2ue9zskj6lhwpz bin]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data
2018-10-13 15:36:40 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2018-10-13 15:36:44 [WARNING] The bootstrap log isn't empty:
2018-10-13 15:36:44 [WARNING] 2018-10-13T07:36:41.045614Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead
[root@izwz97qxc2ue9zskj6lhwpz bin]# cd /usr/local/mysql/support-files
[root@izwz97qxc2ue9zskj6lhwpz support-files]# ./mysql.server start
Starting MySQL.The server quit without updating PID file (/[FAILED]mysql/izwz97qxc2ue9zskj6lhwpz.pid).
[root@izwz97qxc2ue9zskj6lhwpz support-files]# cp -a ./support-files/my-default.cnf /etc/my.cnf #选择y
cp: cannot stat ‘./support-files/my-default.cnf’: No such file or directory
该问题主要为
需要改变系统my.cnf的配置,
解决方案如下
[root@izwz97qxc2ue9zskj6lhwpz support-files]# cd ..
[root@izwz97qxc2ue9zskj6lhwpz mysql]# cp -a ./support-files/my-default.cnf /etc/my.cnf #选择y
cp: overwrite ‘/etc/my.cnf’? y
[root@izwz97qxc2ue9zskj6lhwpz mysql]# cp -a ./support-files/mysql.server /etc/init.d/mysqld
[root@izwz97qxc2ue9zskj6lhwpz mysql]# vim /etc/m.cnf
[root@izwz97qxc2ue9zskj6lhwpz mysql]# vim /etc/my.cnf
[root@izwz97qxc2ue9zskj6lhwpz mysql]# vim /etc/my.cnf
[root@izwz97qxc2ue9zskj6lhwpz mysql]# service mysqld start
Starting MySQL. [ OK ]
5.改变mysql的密码
5.1.获取root用户下的初始密码
[root@izwz97qxc2ue9zskj6lhwpz mysql]# cat /root/.mysql_secret
# Password set for user 'root@localhost' at 2018-10-13 15:36:40
j-i3hZFs8Alf
5.2.linux命令登录mysql
注意下面
bin/mysql -u root -p
命令回车
就是输入上面获取的密码j-i3hZFs8Alf
[root@izwz97qxc2ue9zskj6lhwpz mysql]# bin/mysql -u root -p
Enter password:
