MySQL二进制文件规范安装

操作系统:CentOS 6.7  (64位)

二进制包:MySQL-5.6.30-linux-glibc2.5-x86_64.tar.gz

MySQL 下载地址:

1、下载MySQL

# mkdir /root/mysql

# cd /root/mysql

# wget

2、解压

# cd /opt/
# mkdir mysql
# cd mysql
# tar zxvf /root/mysql/mysql-5.6.30....
# ln -s /opt/mysql/mysql-5.6.30-linux-glibc2.5-x86_64 /usr/local/mysql
# cd /usr/local/mysql

3、创建用户

# groupadd mysql
# useradd -g mysql -M -s /sbin/nologin mysql

4、环境变量

# vim /etc/profile
  PATH=$PATH:/usr/local/mysql
# source /etc/profile

5、创建必须的目录
/data/mysql/mysql3376/
  data  数据目录
   tmp 临时文件
   logs 二进制日志目录
# mkdir -p /data/mysql/mysql3376/{data,tmp,logs}


6、权限
# chown -R mysql:mysql /data/mysql/mysql3376/
# chown -R mysql:mysql /opt/mysql
# chown -R mysql:mysql /usr/local/mysql

7. 创建一个配置文件

[client]
port = 3376
socket = /tmp/mysql3376.sock

# The MySQL server
[mysqld]
# Basic
port = 3376
user = mysql
basedir = /usr/local/mysql
datadir = /data/mysql/mysql3376/data
tmpdir = /data/mysql/mysql3376/tmp
socket = /tmp/mysql3376.sock

log-bin = /data/mysql/mysql3376/logs/mysql-bin
log-error = error.log
slow-query-log-file = slow.log
skip-external-locking
skip-name-resolve
log-slave-updates

8、初始化

# cd /usr/local/mysql
# ./scripts/mysql_install_db --defaults-file=/etc/my.cnf

  看到两次ok

9. 启动 & 关闭

启动:
# /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &

  或者

# /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf &

关闭:
# /usr/local/mysql/bin/mysqladmin -S /tmp/mysql3376.sock shutdown


10、 安全加固

# delete from mysql.user where user!='root' or host!='localhost';
# truncate table mysql.db;
# drop database test;
# flush privileges;

怎么确认mysql是启动起来的?

A 查看进程是否存在
# ps axu |grep mysqld
 B 查看端口是不是监听正确
# ss -lnpt |grep mysqld

C 看看错误日志有无异常
