最近有个项目要用到mysql
于是在mysql的论坛中找到了一个5.6.37版本的
下面介绍怎么安装和使用mysql
下载地址：
https://dev.mysql.com/downloads/mysql/5.6.html--这个是官方的，可能已经失效了
下面这个是我上传到云上的

1.下载并上传到服务器中，进行解压，解压到/usr/local下
[root@zhang ~]# tar xvf mysql-5.6.37-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
改下文件名，这个太长了
[root@zhang local ]# mv mysql-5.6.37-linux-glibc2.12-x86_64 mysql
2.创建mysql的用户和组
创建组：
[root@zhang ~]# groupadd -r -g 306 mysql
创建用户：
[root@zhang ~]# useradd -g 306 -r -u 306 mysql
3.修改目录的所有者和所属组：
[root@zhang ~]# chown -R mysql.mysql /usr/local/mysql/*
创建存储数据文件的目录（如果有的话就不用创建了）
[root@zhang ~]# mkdir -p /usr/local/mysql/mydata/data
修改所有者和所属组
[root@zhang ~]# chown -R mysql.mysql /usr/local/mysql/mydata
ll mydata
4.初始化MySQL：
[root@zhang ~]#cd /usr/local/mysql/
[root@zhang mysql]# scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/mydata/data/
5.创建初始化进程，并添加到/etc/init.d/下
[root@zhang mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@zhang mysql]# chkconfig --add mysqld
6.配置mysql的配置文件
[root@zhang mysql]# vim /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/mydata/data
#socket=/var/lib/mysql/mysql.sock
#user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
#symbolic-links=0
basedir=/usr/local/mysql
port=3306
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
#[mysqld_safe]
#log-error=/var/log/mysqld.log
#pid-file=/var/run/mysqld/mysqld.pid
7.启动mysql进程
[root@zhang mysql]# service mysqld start
8.查看进程是否启动：
[root@zhang mysql]# lsof -i:3306
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
mysqld 26961 mysql 10u IPv6 67261 0t0 TCP *:mysql (LISTEN)
9.配置环境变量：
[root@zhang mysql]# cd /root/
[root@zhang ~]# vim .bash_profile
修改下PATH变量
PATH=$PATH:$HOME/bin:/usr/local/mysql/bin
export PATH
10.给mysql添加密码
[root@zhang ~]# mysqladmin -u root password 'zhang'
11.登录mysql
[root@zhang ~]# mysql -uroot -p
Enter password: zhang
