#1 安裝新版本mysql
## 下載mysql5.7.17，拷貝到server下的/opt檔案目錄下
## 解壓，建立軟連線，授權
tar zvxf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
ln -s /opt/mysql-5.7.17-linux-glibc2.5-x86_64 /usr/local/mysql57
chown -R mysql:mysql /usr/data/mysql57
 
#2 修改配置引數
## 檢查配置檔案中那些配置是使用到了 安裝目錄，把使用到底都修改
舊：
basedir = /usr/local/mysql56
plugin
 
-dir = /usr/local/mysql56/lib/plugin/
 
新：
basedir = /usr/local/mysql
plugin-dir = /usr/local/mysql/lib/plugin/
 
#3 關閉mysql
[[email protected] mysqlup]# /usr/local/mysql56/bin/mysqladmin --socket=/tmp/mysql3399.sock -uroot -p shutdown
Enter password:
[root@sutest244 mysqlup]# ps axu | grep mysql3399 | grep mysqld
 

[[email protected] mysqlup]#
 
#4 新版本啟動mysql
[[email protected] mysqlup]# /usr/local/mysql/bin/mysqld --defaults-file=/data/mysqlup/mysql3399.cnf &
[1] 15477
[root@sutest244 mysqlup]# ps axu | grep mysql3399 | grep mysqld
mysql    15477 37.1 26.7 11931672 1037520 pts/4 Sl  03:34   0:05 /usr/local/mysql/bin/mysqld --defaults-file

[root@sutest244 mysqlup]#
[[email protected] mysqlup]# vim /data/mysqlup/data/error.log
 
#4.1 檢查
檢查啟動後的錯誤日誌，看下是否有配置引數報錯，如果有，修改
錯誤日誌會有大量的字典資訊報錯，這個暫不處理，下個步驟修復
 
#5 升級字典
[[email protected] bin]# /usr/local/mysql/bin/mysql_upgrade --socket=/tmp/mysql3399.sock -uroot -p
