KindEdito从3.51升级到4.0版本流程怎么升级？，是需要修改那些地方，老版本正常使用。官网的升级有点看不明白。本站是php的，知道的帮忙帮忙，说说详细步骤，成功还有重谢！
参考技术A你可以去看看这片神奇的帖子。。
所以说你需要升级啊。。。
MySQL升级指南
I、MySQL跨版本升级
一、MySQL升级说明
1、升级到 5.7 流程：
- 前端业务停服，备份主库和从库数据；先升级从库导入（
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
- 前端业务停服，备份主库和从库数据；先升级从库导入（
二、升级环境说明
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
- MD5: ebc8cbdaa9c356255ef82bd989b07cfb
- 官方下载地址：
MySQL Community Server 5.7.18 Linux Generic x86-64bit - sohu下载地址：
MySQL Community Server 5.7.18 Linux Generic x86-64bit
三、停止应用服务和 MySQL 5.5 实例并备份数据库
1、停止应用服务
- 前端业务停止服务，确认没有MySQL线程连接（show processlist查看）
2、数据库备份说明
- 2.1 、分别导出主库和从库用户权限
- 2.2 、通过
mysqldump对主库和从库进行备份，备份时数据库需要正常运行。 - 2.3 、备份命令 ：mysqldump -uroot -p123456 --single-transaction --master-data=2 -E -R --ignore-table=mysql.* --flush-logs -A >/r2/bak_sql/all_20171201.sql
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)
- 3.1、导出权限并备份数据库
--导出权限 [[email protected](252) /usr/local/src]# cat exp_grants.sh #!/bin/bash #Function export user privileges`: myuser=root #mysql账号 mypwd=123456 #mysql密码，导出完请清除掉脚本账号信息 expgrants() { mysql -B -u${myuser} -p${mypwd} -N [email protected] -e "SELECT CONCAT( ‘SHOW GRANTS FOR ‘‘‘, user, ‘‘‘@‘‘‘, host, ‘‘‘;‘ ) AS query FROM mysql.user" | \ mysql -u${myuser} -p${mypwd} [email protected] | \ sed ‘s/\(GRANT .*\)/\1;/;s/^\(Grants for .*\)/-- \1 /;/--/{x;p;x;}‘ } expgrants > ./grants.sql [[email protected](252) /usr/local/src]# sh exp_grants.sh [[email protected](252) /usr/local/src]# less grants.sql --导出的权限文件 -- Grants for [email protected]% GRANT SELECT, CREATE, RELOAD, PROCESS, SHOW DATABASES, SUPER, LOCK TABLES, REPLICATION CLIENT, SHOW VIEW, EVENT, TRIGGER, CREATE TABLESPACE ON *.* TO ‘dbbackup‘@‘%‘ IDENTIFIED BY PASSWORD ‘*xxxxxxxxxxxxxxx‘; .......- 3.2、mysqldump备份数据库
[[email protected](252) /usr/local/src]# mysqldump -uroot -p123456 --single-transaction --master-data=2 -E -R --ignore-table=mysql.* --flush-logs -A >/r2/bak_sql/all_20171201.sql [[email protected](252) /usr/local/src]# cd /r2/bak_sql/ [[email protected](252) /r2/bak_sql]# ls -lsh total 102M 102M -rw-r--r-- 1 root root 102M 12月 1 17:16 all_20171201.sql- 3.3、关闭 MySQL 5.5 实例
[[email protected](252) /r2/bak_sql]# /etc/init.d/mysqld stop Shutting down MySQL.. SUCCESS! [[email protected](252) /r2/bak_sql]# ps -ef |grep mysqld root 105281 82231 0 18:19 pts/4 00:00:00 grep --color=auto mysqld- 3.4、通过物理备份数据库（
升级失败回退时使用）
-- 在实例关闭之后，通过 cp datadir 目录的方式来备份。 [[email protected](252) /r2/bak_sql]# cd /r2/ [[email protected](252) /r2]# mv mysqldata mysqldatabak
四、升级MySQL版本
1、安装 MySQL 5.7
[[email protected](252) /usr/local/src]# pwd /usr/local/src [[email protected](252) /usr/local/src]# ll |grep mysql -rw-r--r-- 1 root root 654430368 12月 1 16:05 mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz drwxr-xr-x 14 mysql mysql 4096 7月 31 17:03 zabbix-3.2.7 [[email protected](252) /usr/local/src]# mv /usr/local/mysql /usr/local/mysql5.5 [[email protected](252) /usr/local/src]# md5sum mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz --校验tar包MD5与官网MD5对比是否正确 ebc8cbdaa9c356255ef82bd989b07cfb mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz [[email protected](252) /usr/local/src]# tar zxvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz -C /usr/local/ mysql-5.7.18-linux-glibc2.5-x86_64/bin/myisam_ftdump mysql-5.7.18-linux-glibc2.5-x86_64/bin/myisamchk ...... mysql-5.7.18-linux-glibc2.5-x86_64/docs/INFO_SRC [[email protected](252) /usr/local]# ll |grep mysql drwxr-xr-x. 13 root root 4096 3月 9 2016 mysql5.5 drwxr-xr-x 9 root root 4096 12月 4 09:18 mysql-5.7.18-linux-glibc2.5-x86_64 [[email protected](252) /usr/local]# ln -s mysql-5.7.18-linux-glibc2.5-x86_64 mysql [[email protected](252) /usr/local]# ll |grep mysql lrwxrwxrwx 1 root root 34 12月 4 09:20 mysql -> mysql-5.7.18-linux-glibc2.5-x86_64 drwxr-xr-x. 13 root root 4096 3月 9 2016 mysql5.5 drwxr-xr-x 9 root root 4096 12月 4 09:18 mysql-5.7.18-linux-glibc2.5-x86_642、修改相关目录的权限
[[email protected](252) /usr/local]# chown -R mysql.mysql mysql [[email protected](252) /usr/local]# chown -R mysql.mysql mysql-5.7.18-linux-glibc2.5-x86_643、检查改环境变量
[[email protected](252) /r2/mysqldata]# which mysql /usr/local/mysql/bin/mysql --如何没有，在/etc/profile 文件中的添加export PATH=/usr/local/mysql/bin:$PATH 使用 source /etc/profile 刷新配置 [[email protected](252) /r2/mysqldata]# source /etc/profile [[email protected](252) /r2/mysqldata]# which mysql /usr/local/mysql/bin/mysql
五、修改 my.cnf 配置文件并启动 MySQL 5.7
1、修改 my.cnf 配置文件
- 1.1、备份 my.cnf 配置文件
[[email protected](252) /usr/local]# cp /etc/my.cnf /r2/mysqldatabak/my_5.5.33.cnf --备份配置文件- 1.2、参照模板修改
my.cnf配置文件- 模板配置文件如下：

六、导入备份的权限和数据
1、导入权限sql
--直接导入会报错,需要先修改[email protected]密码，然后再导入 [[email protected](252) /r2/mysqldata]# mysql -uroot -p Welcome to the MySQL monitor. Commands end with ; or \g.

[[email protected](252) /r2/mysqldata]# mysql -uroot -pxxxxx </r2/bak_sql/all_20171201.sql- 3、确认升级是否成功
- 检查error，是否有报错
- 重启数据库验证是否有无报错
- 验证账号是否可用（业务部门确认）

[[email protected](252) /r2/mysqldata]# rm /usr/local/src/grants.sql rm: remove regular file ‘/usr/local/src/grants.sql’? YII、升级失败回滚
一、升级回退到mysql5.5
1、关闭数据库

mysql>III、配置主从复制
一、配置基于GTID的并行复制
例如：主库（192.68.48.168）和从库（192.168.24.180）
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） #### slave-parallel-type=LOGICAL_CLOCK #基于组提交的并行复制方式 slave-parallel-workers=24 #并行的SQL线程数量 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
- 2.1.从原主库复制备份文件，从库导入原主库备份文件
[[email protected] r2]# cd bak_sql/ [[email protected] bak_sql]# scp 192.168.48.168:/r2/bak_sql/all_20171201.sql ./- 2.2.建立GTID主从复制

mysql> drop database tttt; Query OK, 1 row affected (0.06 sec)IV、确认服务正常
一、业务开启，观察数据，确认从库是否正常接收到数据

二、备份从库
- 主从正常，从库执行备份
备份命令 ： mysqldump -uroot -p --single-transaction --master-data=2 -E -R --flush-logs -A >/r2/bak_sql/all_XXXXXXX.sql
[[email protected] bak_sql]# mysqldump -uroot -p --single-transaction --master-data=2 -E -R --flush-logs -A >/r2/bak_sql/all_`date +"%Y%m%d"`.sql Enter password: [[email protected] bak_sql]# ll total 269124 -rw-r--r-- 1 root root 275582147 Dec 5 12:38 all_20171205.sql
V、清理升级过程产生的数据
一、清理数据
- 清理备份文件夹/r2/mysqldatabak
- 清理备份文件夹/usr/local/mysql5.5
- 清理权限文件/usr/local/src/grants.sql
