redhat6.5mysql升级5.5.48经mysql5.6.32至mysql5.7.16实施概略

1,os version
redhat 6.5


2,旧版本MySQL 5.5.48创建测试数据库及测试表
mysql> create database zxy;
Query OK, 1 row affected (0.00 sec)


mysql> use zxy;
Database changed
mysql> create table t_zxy(a int);
Query OK, 0 rows affected (0.03 sec)


mysql> insert into t_zxy values(1);
Query OK, 1 row affected (0.01 sec)


mysql> commit;
Query OK, 0 rows affected (0.00 sec)


3，查询旧版本MYSQL 5.5.48 DATA DIR及相关SOCKET文件及PID
mysql> show variables like 'datadir';
+---------------+-----------------+
| Variable_name | Value           |
+---------------+-----------------+
| datadir       | /var/lib/mysql/ |
+---------------+-----------------+
1 row in set (0.00 sec)


mysql> show variables like 'socket';
+---------------+---------------------------+
| Variable_name | Value                     |
+---------------+---------------------------+
| socket        | /var/lib/mysql/mysql.sock |
+---------------+---------------------------+
1 row in set (0.00 sec)


mysql> show variables like '%pid%';
+---------------+---------------------------------+
| Variable_name | Value                           |
+---------------+---------------------------------+
| pid_file      | /var/lib/mysql/mysqlupgrade.pid |
+---------------+---------------------------------+
1 row in set (0.01 sec)


4,旧版本MYSQL 5.5.48没有使用配置文件my.cnf


[root@mysqlupgrade mysql_5548_dir]# ps -ef|grep -i mysql
root      6563  5378  0 16:52 pts/0    00:00:00 /bin/sh /usr/bin/mysqld_safe --user=root

root      6712  5378  0 17:02 pts/0    00:00:00 grep -i mysql




[root@mysqlupgrade mysql_5548_dir]# ps aux|grep mysql|grep -i my.cnf
[root@mysqlupgrade mysql_5548_dir]# 




5,旧版本mysql 5.5.48执行innodb_fast_shutdown=0
[root@mysqlupgrade mysql_5548_dir]# mysql -u root -p --execute='set global innodb_fast_shutdown=0'
Enter password: 
[root@mysqlupgrade mysql_5548_dir]# 




6，shutdown 旧版本mysql 5.5.48
[root@mysqlupgrade mysql_5548_dir]# mysqladmin -u root -p shutdown
Enter password: 
180503 17:04:54 mysqld_safe mysqld from pid file /var/lib/mysql/mysqlupgrade.pid ended
[1]+  Done                    mysqld_safe --user=root
[root@mysqlupgrade mysql_5548_dir]# ps -ef|grep mysql
root      6734  5378  0 17:04 pts/0    00:00:00 grep mysql
[root@mysqlupgrade mysql_5548_dir]# 


7,移除旧版本mysql 5.5.48
[root@mysqlupgrade mysql_5548_dir]# rpm -qa|grep -i mysql
MySQL-devel-5.5.48-1.el6.x86_64
MySQL-server-5.5.48-1.el6.x86_64

[root@mysqlupgrade mysql_5548_dir]# 




[root@mysqlupgrade mysql_5548_dir]# yum -y remove MySQL-client-5.5.48-1.el6.x86_64


[root@mysqlupgrade mysql_5548_dir]# yum -y remove MySQL-server-5.5.48-1.el6.x86_64




[root@mysqlupgrade mysql_5548_dir]# yum -y remove MySQL-devel-5.5.48-1.el6.x86_64




[root@mysqlupgrade mysql_5548_dir]# rpm -qa|grep -i mysql
[root@mysqlupgrade mysql_5548_dir]# 


8,确认旧版本MYSQL 5.5.48 DATA DIR及相关存在
[root@mysqlupgrade mysql_5548_dir]# ll /var/lib/mysql
total 28700
