二进制安装mysql5.6

安装依赖包 

yum install -y libaio

yum install -y perl perl-devel

 

 

 

解压

 

mkdir /opt/mysql

mv mysql-5.6.16-linux-glibc2.5-x86_64.tar.gz /opt/mysql/

 

cd /opt/mysql

tar -zxvf mysql-5.6.16-linux-glibc2.5-x86_64.tar.gz

 

 

 

 

创建一个链接

cd /usr/local

ln -s /opt/mysql/mysql-5.6.16-linux-glibc2.5-x86_64 mysql

 

 

 

创建运行的用户

groupadd mysql

useradd -g mysql -d /usr/local/mysql -s /sbin/nologin -M -n mysql

 

 

 

创建所需要的目录

mkdir -p /data/{mysql,tmp}/

mkdir /var/lib/mysql

 

 

修改权限

chown -R mysql:mysql /usr/local/mysql/

mkdir -p /data/{mysql,tmp}/

chown -R mysql:mysql /data/{mysql,tmp}/

chown mysql:mysql /var/lib/mysql

启动MySQL

cp /opt/mysql/mysql-5.6.16-linux-glibc2.5-x86_64/support-files/mysql.server /etc/init.d/mysqld

 

/etc/init.d/mysqld start 

 

 

 

修改密码

use mysql;
update mysql.user set password=password('chengce243') where user='root' ;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'chengce243';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'chengce243';
