MySQL二进制文件规范安装

演示环境介绍操作系统：CentOS 6.7 （64位）二进制包：mysql-5.6.30-linux-glibc2.5-x86_64.tar.gzMySQL 下载地址：http://dev.mysql.com/downloads/1、下载MySQL# mkdir /root/mysql# cd /root/mysql# wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.30-linux-glibc2.5-x86_64.tar.gz2、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/mysql3、创建用户# groupadd mysql
# useradd -g mysql -M -s /sbin/nologin mysql4、环境变量# vim /etc/profile
PATH=$PATH:/usr/local/mysql
# source /etc/profile5、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/mysql7. 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.socklog-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-updates8、初始化# cd /usr/local/mysql
# ./scripts/mysql_install_db --defaults-file=/etc/my.cnf 看到两次ok9. 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 mysqldC 看看错误日志有无异常本文永久更新链接地址
