mysql5.7.19安装步骤

1、下载
下载地址：http://mirror.switch.ch/mirror/mysql/Downloads
2、安装
#tar zxvf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz -C /usr/local
#Cd /usr/local
#Mv mysql-5.7.19-linux-glibc2.12-x86_64 mysql
#groupadd mysql

useradd -r -g mysql -s /bin/false mysql

#cd /usr/local/mysql
#mkdir mysql-files data
#chown -R mysql.mysql .
创建/etc/my.cnf文件,内容如下：
[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
user=mysql
character-set-server=utf8

Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/tmp/mysqld.pid
