mkdir /data/mysql5.6/data  -p 
mkdir /usr/local/mysql5.6 -p
mkdir /data/mysql5.6/binlog -p

#可使用rz软件，或者xftp6
yum install -y lrzsz
rz -be

tar xf mysql-5.6.44-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.6.44-linux-glibc2.12-x86_64/* /usr/local/mysql5.6/

3、创建用户，修改权限

groupadd mysql
useradd -M -s /sbin/nologin -r -g mysql mysql
chown -R mysql:mysql /usr/local/mysql5.6/ /data/

4、修改配置文件

cat > /etc/my.cnf <<EOF
[mysqld]
basedir=/usr/local/mysql5.6
datadir=/data/mysql5.6/data 
server_id=99
user=mysql
log_bin=/data/binlog/mysql-bin
binlog_format=row
socket=/tmp/mysql.sock 
[mysql]
socket=/tmp/mysql.sock
EOF

5、修改环境变量

vim /etc/profile
export PATH=/usr/local/mysql5.6/bin:$PATH
source /etc/profile

6、初始化数据

yum install -y mariadb-libs
yum install -y libaio-devel
rm -rf /data/mysql5.6/data/*
./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql5.6/

7、使用sysv方式启动数据库

$ cp  /usr/local/mysql5.6/support-files/mysql.server /etc/init.d/mysqld5.6
$ vim /etc/init.d/mysqld5.6
#46行跟47行写入MySQL路径
basedir=/usr/local/mysql5.6
datadir=/data/mysql5.6/data

5、启动数据库

$ /etc/init.d/mysqld5.6 start
#默认是没有密码的需要设置密码
$ mysqladmin -uroot -p password 123
