linux二进制安装mysql：

1.在/usr/local/下创建三个目录：

mkdir /usr/local/mysql/data #用来存放mysql数据和表mkdir /usr/local/mysql/etc #用来存放配置文件mkdir /usr/local/mysql/logs #用来存放mysql日志

2.对权限进行管理：

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

3.对配置文件进行修改，配置文件具体内容：

cat >/usr/local/mysql/etc/my.cnf <<EOF
[mysqld]
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
log-error=/usr/local/mysql/logs/mysqld.log
pid-file=/usr/local/mysql/logs/mysqld.pid
EOF

 或直接打开配置文件添加vim /usr/local/mysql/etc/my.cnf ：

[mysqld]
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
log-error=/usr/local/mysql/logs/mysqld.log
pid-file=/usr/local/mysql/logs/mysqld.pid

4.再cd /usr/local/mysql执行以下命令：

bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

5.接着启动mysql服务：

/mysql/support-file/mysql.server stsrt

 进入mysql:

/usr/local/mysql/bin/mysql

6.补充第一次安装会有一个临时密码：

查看后登录再对mysql密码进行修改即可：

more logs/mysqld.log
