先检查linux服务器上是否已经安装了mysql
[root@localhost ~]# rpm -qa | grep mysql
未安装则无任何信息返回，若已安装则会返回已安装的版本信息，可通过--nodeps关键字卸载mysql
[root@localhost local]#rpm -e 返回的mysql版本信息 –nodeps
2. 下载mysql安装包mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz
把下载的安装包解压到/usr/local目录里，重命名目录为mysql
[root@localhost ~]# tar -zxf mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz -C /usr/local
[root@localhost local]# mv mysql-5.6.33-linux-glibc2.5-x86_64 mysql
3. 创建mysql用户组及用户
[root@localhost local]# groupadd mysql
[root@localhost local]# useradd -r -g mysql mysql
4. 进入mysql目录，对用户mysql和分组mysql进行授权
[root@localhost mysql]# chown -R mysql:mysql ./
5. 进入/mysql/scripts/目录执行mysql_install_db脚本
[root@localhost mysql]# cd scripts/
[root@localhost scripts]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/mysql.pid --tmpdir=/tmp
安装报错，可直接在线安装perl和autoconf
[root@localhost scripts]# yum install perl
[root@localhost scripts]# yum -y install autoconf
再次执行上面的脚本
6. 配置my.cnf
[root@localhost scripts]# vi /etc/my.cnf
datadir = /usr/local/mysql/data
log-error = /usr/local/mysql/data/error.log
pid-file = /usr/local/mysql/data/mysql.pid
user = mysql
tmpdir = /tmp
7. 设置启动脚本
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# chmod 755 /etc/init.d/mysqld
8. 启动服务
service mysqld start
9. 进入bin目录连接数据库./mysql ，修改root的用户密码和允许远程连接
mysql> use mysql;
mysql> update user set password=passworD("123456") where user='root';
mysql> flush privileges;
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
mysql> flush privileges;
