CentOS7安装MySQL5.6详细步骤

一、安装依赖包

yum -y install make gcc-c++ cmake bison-devel ncurses-devel libaio libaio libaio-devel perl-Data-Dumper net-tools

二、创建用户

useradd mysql

passwd mysql

三、创建相关目录

mkdir -p /mofeng/{data,local,log,etc,package,src,tmp}

chmod 777 /mofeng/tmp

mkdir -p /mofeng/data/mysql/3306/{binlog,data,etc,pid,socket,tmp}

mkdir -p /mofeng/log/mysql

chown -R mysql:mysql /mofeng/data/mysql

四、解压源码包

tar zxvf mysql56.tar.gz -C /mofeng/local/

五、拷贝配置文件

mv my.cnf /mofeng/data/mysql/3306/etc/

六、初始化数据库

/mofeng/local/mysql56/scripts/mysql_install_db –defaults-file=/mofeng/data/mysql/3306/etc/my.cnf –basedir=/mofeng/local/mysql56 –datadir=/mofeng/data/mysql/3306/data –plugin-dir=/mofeng/local/mysql56/lib/plugin –user=mysql –log-error=/mofeng/log/mysql/mysql-error.log –open-files-limit=65535 –pid-file=/mofeng/data/mysql/3306/pid/mysql.pid –socket=/mofeng/data/mysql/3306/socket/mysql.sock –port=3306

七、启动数据库

cd /mofeng/local/mysql56

./bin/mysqld_safe –defaults-file=/mofeng/data/mysql/3306/etc/my.cnf &

八、修改数据库root用户密码

/mofeng/local/mysql56/bin/mysqladmin -u root password PASSWORD -S /mofeng/data/mysql/3306/socket/mysql.sock

九、登陆数据库

/mofeng/local/mysql56/bin/mysql -u root -p -S /mofeng/data/mysql/3306/socket/mysql.sock

十、关闭防火墙，修改selinux

1. Disable Firewalld Service.

systemctl mask firewalld

2. Stop Firewalld Service.

systemctl stop firewalld

十一、允许客户端登陆数据库

grant all on . to root@”%” identified by ‘NEW_PASSWORD’;

FLUSH PRIVILEGES;

十二、关闭数据库

/mofeng/local/mysql56/bin/mysqladmin shutdown -S /mofeng/data/mysql/3306/socket/mysql.sock -u root -p
