centos6.5环境通达OA数据库mysql5.0.67升级至mysql5.5.48方案

centos6.5环境通达OA数据库mysql5.0.67升级至mysql5.5.42方案

整体方案：

环境准备，在备用服务器安装mysql5.5数据库

1、停用生产环境的应用访问

直接修改web的访问端口，避免在更换过程中有人访问

Listen 1888

2、停用数据库服务并备份数据库

# /opt/lampp/lampp stopmysql

# cd /opt/lampp/var/mysql

# cp -r TD_OA TD_OA20160409

将备份文件上传到目标服务器8.68

3、添加系统自动添加账号的函数

4、修改原8.200的IP为8.201，备机服务器8.68IP更换为8.200

修改前端数据库连接

/opt/lampp/htdocs/MYOA/webroot/inc/oa_config.php

5、启动mysql服务，测试能否正常连接

# service mysqld start

6、测试常用的流程，把之前修改的前端listen端口该回来成8888，恢复访问

7、启用数据库同步

具体实施步骤

一、安装cmake编译工具和依赖环境

跨平台编译器

查看是否已经安装了gcc

# rpm -qa | grep gcc

# yum install -y gcc-c++

# yum install -y cmake

# yum install -y git

解决依赖关系

# yum install readline-devel zlib-devel openssl-devel

Warning: Bison executable not found in PATH

解决方法：

# yum install -y bison

再次编译即通过

二、编译安装mysql-5.5.48

# tar xf mysql-5.5.48.tar.gz

# cd mysql-5.5.48

# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mydata -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DWITH_SSL=system -DWITH_ZLIB=system -DWITH_LIBWRAP=0
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci

# make && make install

编译报错需要删除编译缓存

rm CMakeCache.txt

三、新建存放Mysql数据库文件的逻辑卷并挂载到/data/mydata下

分区

# fdisk /dev/sda

n

p

3

+20G

w

#挂载系统分区

# kpartx -l /dev/sda

# kpartx -af /dev/sda

# partx -a /dev/sda

验证是否挂载成功

# cat /proc/partitions

创建物理卷

# pvcreate /dev/sda3

创建名为myvg的卷组

# vgcreate myvg /dev/sda3

#创建一个大小为15G，名字叫做mylv的逻辑卷

# lvcreate -L 15G -n mylv myvg

格式化

# mke2fs -t ext4 -b 2048 /dev/myvg/mylv

# mkdir -pv /data/mydata

mkdir: created directory ‘/data’

mkdir: created directory ‘/data/mydata’

# mount /dev/myvg/mylv /data/mydata

# vim /etc/fstab

添加如下内容：

/dev/myvg/mylv /data/mydataext4defaults,noatime 0 0

四、创建Mysql用户

添加mysql用户指定组id和用户id为306

# groupadd -r -g 306 mysql

# useradd -g mysql -r -g 306 -s /sbin/nologin mysql

# id mysql

uid=994(mysql) gid=306(mysql) groups=306(mysql)

改变数据存储目录和安装目录的权限

# cd /usr/local/mysql

添加存放日志的目录

# mkdir /data/binlogs

# chown -R :mysql ./*

# chown -R mysql.mysql /data/mydata

五、启动脚本初始化数据库

# scripts/mysql_install_db --user=mysql --datadir=/data/mydata^C

# cp support-files/mysql.server /etc/rc.d/init.d/mysqld

# cp support-files/my-large.cnf /etc/my.cnf

编辑/etc/my.cnf配置，加入以下内容

innodb_file_per_table = ON

datadir = /data/mydata

log-bin=/data/binlogs/mysql-bin

把mysqld服务加入到启动项

# chkconfig --add mysqld

# chkconfig --list mysqld

将mysql命令加入环境变量中

vim /etc/profile.d/mysql.sh

加入

export PATH=/usr/local/mysql/bin:$PATH

启动mysqld服务

# service mysqld start

报错

Starting MySQL. ERROR! The server quit without updating PID file (/data/mydata/oadb-test.pid).

# ss -tnl

可以观察日志/data/mydata/oadb-test.err，是日志创建权限的问题

# chown -R mysql.mysql /data

六、上传通达OA数据库并配置相关权限

上传通达OA数据库到服务器上，修改权限，并重启服务，测试

# chown -R mysql.mysql /data/mydata

# service mysqd restart

对mysql数据库用户进行清理，加密码

mysql> use mysql

Database changed

mysql> select user,host,password from user;

+------+-----------+----------+

| user | host | password |

+------+-----------+----------+

| root | localhost | |

| root | adb-test | |

| root | 127.0.0.1 | |

| root | ::1 | |

| | localhost | |

| | adb-test | |

+------+-----------+----------+

6 rows in set (0.01 sec)

mysql> delete from user where user='' and host='localhost';

Query OK, 1 row affected (0.01 sec)

mysql> delete from user where user='' and host='adb-test';

Query OK, 1 row affected (0.00 sec)

设置其中root密码为myoa888，并对服务器IP限制

mysql> update user set password=PASSWORD('myoa888'),host='192.168.11.144' where user='root' and host='::1';

Query OK, 1 row affected (0.00 sec)

Rows matched: 1 Changed: 1 Warnings: 0

对root用户加密

mysql> update user set password=PASSWORD('13C1325E831DEC8D60') where user='root' and host in('localhost','adb-test','127.0.0.1');

mysql> select user,host,password from user;

+------+----------------+-------------------------------------------+

| user | host | password |

+------+----------------+-------------------------------------------+

| root | localhost | *CF51F9E245F41378E51B4154082F26108A5B0D63 |

| root | adb-test | *CF51F9E245F41378E51B4154082F26108A5B0D63 |

| root | 127.0.0.1 | *CF51F9E245F41378E51B4154082F26108A5B0D63 |

| root | 192.168.11.144 | *91AF99F23C3D4ED85140D100433725DFA52BECEE |

+------+----------------+-------------------------------------------+

后续的功能增强：

一、关于数据库交互函数的设置：

①OA数据库设置

TD_OA

字符集gbk -- GBK Simplified Chinese

排序规则gbk_chinese_ci

②建立编码表

CREATE TABLE `cs_char2letter` (

`PY` char(1) character set utf8 NOT NULL,

`HZ` char(1) NOT NULL default '',

PRIMARY KEY (`PY`)

) ENGINE=InnoDB DEFAULT CHARSET=gbk;

③插入

truncate table cs_char2letter;

set names gbk;

insert into cs_char2letter values

('A','骜'),

('B','簿'),

('C','错'),

('D','鵽'),

('E','樲'),

('F','鳆'),

('G','腂'),

('H','夻'),

('J','攈'),

('K','穒'),

('L','鱳'),

('M','旀'),

('N','桛'),

('O','沤'),

('P','曝'),

('Q','囕'),

('R','鶸'),

('S','蜶'),

('T','箨'),

('W','鹜'),

('X','鑂'),

('Y','韵'),

('Z','咗');

④建立函数

DELIMITER $$

DROP FUNCTION IF EXISTS `test`.`func_get_first_letter`$$

CREATE DEFINER=`root`@`localhost` FUNCTION `func_get_first_letter`(words varchar(255)) RETURNS char(1) CHARSET gbk

BEGIN

declare fpy char(1);

declare pc char(1);

declare cc char(4);

set @fpy = UPPER(left(words,1));

set @pc = (CONVERT(@fpy USING gbk));

set @cc = hex(@pc);

if @cc >= "8140" and @cc <="FEA0" then

begin

select PY from cs_char2letter where hz>=@pc limit 1 into @fpy;

end;

end if;

Return @fpy;

END$$

DELIMITER;

报错：

This function has none of DETERMINISTIC, NO SQL解决办法

创建存储过程时

出错信息：

[Err] 1418 - This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)

原因：

这是我们开启了bin-log, 我们就必须指定我们的函数是否是

1 DETERMINISTIC 不确定的

2 NO SQL 没有SQl语句，当然也不会修改数据

3 READS SQL DATA 只是读取数据，当然也不会修改数据

4 MODIFIES SQL DATA 要修改数据

5 CONTAINS SQL 包含了SQL语句

其中在function里面，只有 DETERMINISTIC, NO SQL 和 READS SQL DATA 被支持。如果我们开启了 bin-log, 我们就必须为我们的function指定一个参数。

解决方法：

SQL code

mysql> show variables like 'log_bin_trust_function_creators';

+---------------------------------+-------+

| Variable_name | Value |

+---------------------------------+-------+

| log_bin_trust_function_creators | OFF |

+---------------------------------+-------+

1 row in set (0.00 sec)

mysql> set global log_bin_trust_function_creators=1;

mysql> show variables like 'log_bin_trust_function_creators';

+---------------------------------+-------+

| Variable_name | Value |

+---------------------------------+-------+

| log_bin_trust_function_creators | ON |

+---------------------------------+-------+

这样添加了参数以后，如果mysqld重启，那个参数又会消失，因此记得在/etc/my.cnf配置文件中添加：

log_bin_trust_function_creators=1

二、对数据库每天进行自动备份，保留15天以内的备份(myisam引擎,innodb数据库引擎不能直接拷贝的方式备份)

1、创建保存mysql数据库备份文件的目录mysqlbak

mkdir -pv /backup/mysqlbak

修改属主属组

chown -R mysql.mysql /backup

编辑shell脚本

vim /usr/sbin/bakmysql

加入如下内容：

#关闭mysql数据库服务

service mysqld stop

#创建以当前日期为名称的目录

cd /backup/mysqlbak

time=$(date '+%Y%m%d')

mkdir $time

cp /data/mydata/TD_OA/*.* /backup/mysqlbak/$time

#备份完成后开启mysql数据库服务

service mysqld start

#删除15天以前的备份

find /backup/mysqlbak -type d -mtime +15 -exec rm -rf {} \;

3、修改文件属性，使其可执行

chmod +x /usr/sbin/bakmysql

4、修改/etc/crontab

vim /etc/crontab

#每天3点执行脚本

01 3 * * * mysql /usr/sbin/bakmysql

5、重新启动crond

/etc/rc.d/init.d/crond restart

三、将备份到本机的数据库文件同步备份到其他服务器

安装vsftp服务，并添加对应的ftp用户指向备份文件夹，在数据库备份服务器启用同步计划

四、参数的调整

[client]
port		= 3306
socket		= /tmp/mysql.sock
[mysqld]
port		= 3306
default-storage-engine=MyISAM
max_connections=1500
socket		= /tmp/mysql.sock
skip-external-locking
key_buffer_size = 4096M
max_allowed_packet = 64M
table_open_cache = 2400
open_files_limit=65535
tmp_table_size=256M
sort_buffer_size = 16M
read_buffer_size = 16M
read_rnd_buffer_size = 16M
myisam_sort_buffer_size = 128M
thread_cache_size = 256
query_cache_type=0
query_cache_size= 512M
innodb_buffer_pool_size = 1024M
skip-name-resolve
wait_timeout=300
thread_concurrency = 8
innodb_buffer_pool_instances = 35
innodb_file_per_table = 1
datadir = /data/mydata
log-bin=/data/binlogs/mysql-bin
binlog-do-db=TD_OA
expire_logs_day=30
max_binlog_size = 200M
slow_query_log=ON
slow-query-log-file=/data/binlogs/slow_query.log
long_query_time=2
log_bin_trust_function_creators=1
binlog_format=mixed
server-id	= 1
[mysqldump]
quick
max_allowed_packet = 64M
[mysql]
no-auto-rehash
[myisamchk]
key_buffer_size = 1024M
sort_buffer_size = 512M
read_buffer = 256M
write_buffer = 256M
[mysqlhotcopy]
interactive-timeout

记得添加

open_files_limit=65535

否则报错如下：

错误#23: Out of resources when opening file './TD_OA/USER.MYD' (Errcode: 24)

SQL语句: SELECT * from USER where USER_ID='admin' or BYNAME='admin'

修改/etc/security/limits.conf，然后加入以下内容，退出再重新登陆即可(不需要重启，退出当前的连接shell即可)

# ulimit -n 查看参数是否生效

#@student - maxlogins 4

* - nproc 1006154

* - nofile 1006154

# End of file

* soft nofile 1006154

* hard nofile 1006154
