现在源库是腾讯云服务器上面自建的mysql5.1版本,现在打算把数据迁移到新购买的腾讯云mysql5.5版本上,但是在源库设置的变量中有以下问题: 由于源库是mysql5.1版本,没有binlog_row_image这个变量,没法按文档那样设置成 set global binlog_row_image=FULL;那样,没有这个变量设置会不会影响我从源库mysql5.1迁移到腾讯云mysql5.5上面的呢?还有我源库本来的变量log_bin=ON呢,需不需要修改my.cnf里的log-bin=[自定义binlog文件名]这一项呢?我动态修改变量后需不需要对源库进行mysql重启呢?

要弄清楚如何在雪豹10.6.2上启动和运行MySQL和mysql,实在是一项艰巨的任务。我听从了各种职位的指示,但尚未成功:
我从源代码构建了MySQL版本5.1.39,并成功地安装了它。在尝试使用(mysql -u root -p)登录时,mysql返回以下错误:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
这显然意味着MySQL服务器(mysqld)没有运行。
which mysql: /usr/local
