centos7使用rpm包安装mysql5.74

rpm 下载地址：https://dev.mysql.com/downloads/repo/yum/

1.由于CentOS7开始自带的数据库是mariadb，所以需要卸载系统中的mariadb组件，才能安装mysql的组件

[root@localhost opt]# rpm -qa | grep mariadb

[root@localhost opt]# yum -y remove mariadb-libs

 

2.安装mysql，由于依赖关系，所以需要顺序安装rpm包

 

[root@localhost mysql57]# rpm -ivh mysql-community-common-5.7.26-1.el7.x86_64.rpm 
warning: mysql-community-common-5.7.26-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

[root@localhost mysql57]# 

3.启动mysql并设置开机自启

[root@localhost mysql57]# systemctl start mysqld

[root@localhost mysql57]# ps aux|grep mysql

mysql     48505  2.4  4.4 1119716 173068 ?      Sl   17:07   0:00 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid

root      48534  0.0  0.0 112812   972 pts/0    S+   17:08   0:00 grep --color=auto mysql

[root@localhost mysql57]# systemctl enable mysqld

[root@localhost mysql57]# systemctl status  mysqld

 

 

 

4.获取mysql临时密码，设置mysql的root用户密码

 

[root@localhost mysql57]# grep "password" /var/log/mysqld.log

 

 

5.查看mysql配置文件位置命令

[root@localhost etc]# which mysql

/usr/bin/mysql

[root@localhost etc]# /usr/bin/mysql --verbose --help |grep -A 1 'Default options'

Default options are read from the following files in the given order:

/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf

6.关于mysql的一些优化配置
