MySQL 5.6.27 升级 MySQL 5.7.18 版本的升级步骤是怎么样的，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面丸趣 TV 小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
名称 升级前 升级后 备注
OS 版本 CentOS release 6.5 CentOS release 6.5
MySQL 版本 5.6.27 社区版 64bit 5.7.13 社区版 64bit Linux Generic Binaries
MySQL 安装路径 /usr/local/mysql /opt/app/mysql/5.7.13
My.cnf 存放路径 /etc/my.cnf /etc/my.cnf
Mysql basedir /usr/local/mysql /opt/app/mysql/5.7.13
Mysql Datadir /database/mysql3306/data /database/mysql/data
一. 下载 MySQL 5.7.18
从官网下载 mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
官网 地址： http://dev.mysql.com/downloads/mysql/
# mkdir -p /opt/app/mysql
# tar zxvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz -C /opt/app/mysql
# mv /opt/app/mysql/mysql-5.7.18-linux-glibc2.5-x86_64 /opt/app/mysql/5.7.18
chown -R mysql.mysql /opt/app/mysql/5.7.18/
二. 关闭 MySQL 5.6.27 实例
[root@chengshuidai ~]# service mysqld stop
Shutting down MySQL.. SUCCESS!
确认不存在 mysql 进程:
[root@chengshuidai ~]# ps -ef | grep mysqld | grep -v grep
三. 备份 MySQL 5.6.27 数据库:
1). 确认数据文件路径:
# cat /etc/my.cnf | grep datadir
datadir = /database/mysql/data
# cd /database
# pwd
/database
2). 开始备份数据文件:
# cp -r mysql mysql3306
3). 备份参数文件:
# cp /etc/my.cnf /etc/5.6.27_my.cnf
四. 正式修改 my.cnf 配置文件 # 主要修改 basedir
将 /etc/my.cnf 文件中的“basedir = /usr/local/mysql”替换成“basedir = /opt/app/mysql/5.7.18”，
然后保存所做的修改！
1). 启动 MySQL 5.7.18
/opt/app/mysql/5.7.18/bin/mysqld –defaults-file=/etc/my.cnf
启动报错:
[root@chengshuidai mysql]# /opt/app/mysql/5.7.18/bin/mysqld –defaults-file=/etc/my.cnf
[1] 12747
[root@chengshuidai mysql]# 2017-04-27T05:48:11.328215Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use –explicit_defaults_for_timestamp server option (see documentation for more details).

加 –user=root 后启动依然报错:
[root@chengshuidai mysql]# /opt/app/mysql/5.7.18/bin/mysqld –defaults-file=/etc/my.cnf –user=root
[1] 12754
[root@chengshuidai mysql]# 2017-04-27T05:50:00.048115Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use –explicit_defaults_for_timestamp server option (see documentation for more details).

解决方法：
# vi /etc/my.cnf
log_bin=mysql-bin
server_id=58 – 加入 server_id 内容
再次启动, 成功:
[root@chengshuidai mysql]# /opt/app/mysql/5.7.18/bin/mysqld –defaults-file=/etc/my.cnf –user=root
[1] 12768
