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.gz
MySQL 下载地址:
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.gz
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/mysql3、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 = 3376socket = /tmp/mysql3376.sock# The MySQL server[mysqld]# Basicport = 3376user = mysqlbasedir = /usr/local/mysqldatadir = /data/mysql/mysql3376/datatmpdir = /data/mysql/mysql3376/tmpsocket = /tmp/mysql3376.socklog-bin = /data/mysql/mysql3376/logs/mysql-binlog-error = error.logslow-query-log-file = slow.logskip-external-lockingskip-name-resolvelog-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 mysqldC 看看错误日志有无异常
