标签：load read x86_64 ldo 登录 调整 ash hang mysql5.7
1、升级到 5.7 流程：
从库权限+主库备份），后升级主库（主库权限+主库备份），重建主从同步，前端业务开服1、升级环境
| 名称 | 升级前 | 升级后 | 备注 |
|---|---|---|---|
| OS 版本 | RHEL 7.3 x86_64 | RHEL 7.3 x86_64 | |
| MySQL 版本 | 5.5.33-log | 5.7.18-log | Linux Generic Binaries |
| MySQL 安装目录 | /usr/local/mysql5.5 | /usr/local/mysql5.7.18 | |
| MySQL Basedir | /usr/local/mysql | /usr/local/mysql | 通过链接的方式 |
| MySQL Datadir | /r2/mysqldata | /r2/mysqldata | |
| MySQL Port | 3306 | 3306 | |
| my.cnf 路径 | /etc/my.cnf | /etc/my.cnf |
2、安装包下载地址
1、停止应用服务
2、数据库备份说明
mysqldump对主库和从库进行备份，备份时数据库需要正常运行。3、备份数据库并关闭MySQL 5.5实例，主库和从库都需要操作步骤(3.1~3.4)

1、从库（192.168.24.180）
从库my.cnf添加并行复制参数，修改server-id=2
### 开启并行复制（从库） ####

master-info_repository=TABLE #master信息以表的形式保存
relay_log_info_repository=TABLE #slave信息以表的形式保存
relay_log_recovery=ON #relay_log自我修复2、建立主从复制
