标题：mysql 5.5二进制文件安装

作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

1、创建相关目录用户
su – root
groupadd mysql
useradd -g mysql -p xifenfei -s /bin/bash -m mysql -d /opt/mysql
MYSQL_BASE=/opt/mysql
mkdir -p $MYSQL_BASE/product/5.5
mkdir -p $MYSQL_BASE/mysqldata
mkdir -p $MYSQL_BASE/mysqllog
mkdir -p /var/run/mysqld/
chmod -R 777 $MYSQL_BASE
chown -R mysql:mysql $MYSQL_BASE
chown -R mysql:mysql /var/run/mysqld

3、环境变量配置
export MYSQL_BASE=/opt/mysql
export basedir=$MYSQL_BASE/product/5.5
export datadir=$MYSQL_BASE/mysqldata
export LD_LIBRARY_PATH=$basedir/lib:/lib:/usr/lib:/usr/local/lib
export TMPDIR=/tmp
export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH=$basedir:$basedir/bin:${PATH}:$LD_LIBRARY_PATH

4、调整mysql 用户系统限制（可选）
编辑文件：/etc/security/limits.conf 加入以下语句：
mysql soft nproc 2047
mysql hard nproc 16384
mysql soft nofile 1024
mysql hard nofile 65536
确认如下语句是否存在于/etc/pam.d/login，如果不存在请增加：
session required pam_limits.so
如果用户SHELL 用的是Bourne, Bash, 或者Korn shell 修改/etc/profile，并增加如
下内容。(在SuSe 操作系统上，则需要修改/etc/profile.local)：
if [ $USER = "mysql" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi

5、安装数据库
5.1）解压数据库至/opt/mysql/product/5.5中
5.2）安装数据
[mysql@localhost ~]$ cd product/5.5/scripts/
[mysql@localhost scripts]$ ./mysql_install_db –basedir=$basedir –datadir=$datadir –user=mysql

5.3)设置my.cnf参数
vi /etc/my.cnf

[mysqladmin]
socket =/var/run/mysqld/mysqld.sock
[client]
port = 3306
socket =/var/run/mysqld/mysqld.sock
[mysqld]

sort_buffer_size = 512M
read_buffer = 8M
write_buffer = 8M
[mysqlhotcopy]
interactive-timeout
[mysqld_safe]
open-files-limit = 8192

5.4）异常处理
5.4.1）直接通过mysqld_safe不能正常启动数据库
ln -s /opt/mysql/product/5.5 /usr/local/mysql
或者
ln -s /opt/mysql/product/5.5/bin/mysqld /usr/local/mysql/bin/mysqld

5.4.2）mysql_secure_installation不能正常执行
1)
执行：/opt/mysql/product/5.5/bin/mysql_secure_installation出现以下错误，解决方法（ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock）
Enter current password for root (enter for none):
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

2)
修改mysql_secure_installation 脚本的do_query 函数（推荐处理方法）
do_query() {
echo “$1″ >$command
#sed ‘s,^,> ,’ < $command # Debugging # mysql --defaults-file=$config <$command ----此行修改如下： mysql --defaults-extra-file=$config <$command return $? } 6、添加开机启动服务
修改mysql.server文件
basedir=/opt/mysql/product/5.5
datadir=/opt/mysql/mysqldata
[root@localhost ~]# cp /opt/mysql/product/5.5/support-files/mysql.server /etc/init.d/mysqld
[root@localhost ~]# chkconfig –add mysqld
[root@localhost ~]# chkconfig mysqld on
[root@localhost ~]# chkconfig –list mysqld
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off

[mysqld]
ndbcluster
ndb-connectstring=192.168.11.12
[mysql_cluster]
ndb-connectstring=192.168.11.12

创建ndbdata文件夹
mkdir /opt/mysql_cluster/ndbdata

启动ndb节点
/opt/mysql_cluster/bin/ndbd –defaults-file=/opt/mysql_cluster/my.cnf –initial

五、SQL节点配置(mysql)
初始化sql节点
/opt/mysql_cluster/scripts/mysql_install_db –user=mysql –datadir=/opt/mysql_cluster/data –basedir=/opt/mysql_cluster/

配置my.cnf文件(root)
mv /opt/mysql_cluster/my-large.cnf /etc/my.cnf
添加
[mysqld]
ndbcluster
ndb-connectstring=192.168.11.12
[mysql_cluster]

1.安装cmake
1）下载cmake
#wget http://www.cmake.org/files/v2.8/cmake-2.8.3.tar.gz
2）解压cmake
#tar -zvxf cmake-2.8.3.tar.gz
3）配置编译
#cd cmake-2.8.3
#yum -y install gcc
#yum -y install gcc-c++
#./configure
#make
#make install

2.安装MYSQL
1）下载MYSQL
mkdir /opt/mysql_src
#cd /opt/mysql_src
#wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.14.tar.gz/from/http://mysql.mirror.rafal.ca/
2）解压mysql-5.5.14.tar.gz
#tar -zvxf mysql-5.5.14.tar.gz

创建目录（mysql5.5默认已经没有data目录了）
mkdir -p /opt/mysql_src/product
mkdir -p /opt/mysql_src/data

3)配置编译
#cd mysql-5.5.14
#cmake . ##这个方法，安装路径默认

执行mysql_secure_installation报错
错误现象：
Enter current password for root (enter for none):
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)
错误原因：
mysql_secure_installation ignores –socket
解决方案：
1）ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock
2）修改mysql_secure_installation 脚本的do_query 函数（推荐处理方法）
do_query() {
echo “$1″ >$command
#sed ‘s,^,> ,’ < $command # Debugging # mysql --defaults-file=$config <$command ----此行修改如下： mysql --defaults-extra-file=$config <$command return $? } 使用mysqld_safe启动msql错误
见mysqld_safe启动报错

注意：如果想把错误日志放到专门的日志目录中，需要在my.cnf中添加log-error=path选项

使用二进制编译文件的mysqld_safe启动报错，如下：
[mysql@ECP-UC-DB1 ~]$ mysqld_safe
110707 21:31:19 mysqld_safe Logging to ‘/opt/mysql/mysqldata/ECP-UC-DB1.err’.
110707 21:31:19 mysqld_safe The file /usr/local/mysql/bin/mysqld
does not exist or is not executable. Please cd to the mysql installation
directory and restart this script from there as follows:
./bin/mysqld_safe&
See http://dev.mysql.com/doc/mysql/en/mysqld-safe.html for more information

解决方法：
su – root
mkdir /usr/local/mysql/bin
ln -s /opt/mysql/product/5.5/bin/mysqld /usr/local/mysql/bin/mysqld

再次执行mysqld_safe
[mysql@ECP-UC-DB1 ~]$ mysqld_safe
110707 21:32:37 mysqld_safe Logging to ‘/opt/mysql/mysqldata/ECP-UC-DB1.err’.
110707 21:32:37 mysqld_safe Starting mysqld daemon with databases from /opt/mysql/mysqldata

启动结果：
mysql 26885 23452 0 21:32 pts/0 00:00:00 /bin/sh /opt/mysql/product/5.5/bin/mysqld_safe
mysql 27653 26885 0 21:32 pts/0 00:00:00 /usr/local/mysql/bin/mysqld –basedir=/opt/mysql/product/5.5 –datadir=/opt/mysql/mysqldata –plugin-dir=/usr/local/mysql/lib/plugin –log-error=/opt/mysql/mysqldata/ECP-UC-DB1.err –open-files-limit=8192 –pid-file=/var/run/mysqld/mysqld.pid –socket=/var/run/mysqld/mysqld.sock –port=3306

问题存在原因：
1、mysqld_safe只认识/usr/local/mysql/bin/mysqld（也许是配置问题）
2、my.cnf只能放置在/etc/下面，不然使用–defaults-file也不能读取my.cnf文件（有疑惑）

标题：mysql 安装并启动多个实例

作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

1、数据库实例目录
drwxrwxrwx 6 mysql mysql 4096 Jul 6 23:25 mysqldata
drwxrwxr-x 5 mysql mysql 4096 Jul 6 23:23 mysqldata1
drwxrwxr-x 5 mysql mysql 4096 Jul 6 23:27 mysqldata2

2、创建实例
/opt/mysql/product/5.5/scripts/mysql_install_db –basedir=/opt/mysql/product/5.5 –datadir=/opt/mysql/mysqldata –user=mysql
/opt/mysql/product/5.5/scripts/mysql_install_db –basedir=/opt/mysql/product/5.5 –datadir=/opt/mysql/mysqldata1 –user=mysql
/opt/mysql/product/5.5/scripts/mysql_install_db –basedir=/opt/mysql/product/5.5 –datadir=/opt/mysql/mysqldata2 –user=mysql

3、修改my.cnf文件
[mysqld_multi]
mysqld = /opt/mysql/product/5.5/bin/mysqld
mysqladmin = /opt/mysql/product/5.5/bin/mysqladmin
user = root
password = passw0rd

[mysqld3306]
port = 3306
socket = /var/run/mysqld/mysqld3306.sock
pid-file = /var/run/mysqld/mysqld3306.pid
basedir = /opt/mysql/product/5.5
datadir = /opt/mysql/mysqldata

[mysqld3307]
port = 3307
socket = /var/run/mysqld/mysqld3307.sock
pid-file = /var/run/mysqld/mysqld3307.pid
basedir = /opt/mysql/product/5.5
datadir = /opt/mysql/mysqldata1

[mysqld3307]
port = 3307
socket = /var/run/mysqld/mysqld3308.sock
pid-file = /var/run/mysqld/mysqld3308.pid
basedir = /opt/mysql/product/5.5
datadir = /opt/mysql/mysqldata2
注：其他无关参数省略，日志等文件路径也不能相同（未写明）

4、启动数据库
mysqld_multi –defaults-file=/etc/mysql/my.cnf start 3306
mysqld_multi –defaults-file=/etc/mysql/my.cnf start 3307
mysqld_multi –defaults-file=/etc/mysql/my.cnf start 3308

5、登录数据库修改root密码
mysql -S /var/run/mysqld/mysqld3306.sock
mysql -S /var/run/mysqld/mysqld3307.sock
mysql -S /var/run/mysqld/mysqld3308.sock

use mysql
UPDATE user SET password=PASSWORD(‘passw0rd’) WHERE user=’root’;
FLUSH PRIVILEGES;
说明：三个库上分别操作

6、关闭数据库
mysqld_multi –defaults-file=/etc/mysql/my.cnf stop 3306
mysqld_multi –defaults-file=/etc/mysql/my.cnf stop 3307
mysqld_multi –defaults-file=/etc/mysql/my.cnf stop 3308

7、全部启动/关闭
mysqld_multi –defaults-file=/etc/mysql/my.cnf start 3306-3308
mysqld_multi –defaults-file=/etc/mysql/my.cnf stop 3306-3308

标题：使用xtrabackup 配置主从服务器

作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

1、备份主机数据
innobackupex –user=root –password=xifenfei –defaults-file=/etc/my.cnf –stream /tmp/mysql 2>/tmp/mysql.log | gzip> /tmp/data/mysql.tar.gz

2、查看/tmp/mysql.log，记录下当前日志位置
innobackupex: MySQL binlog position: filename ‘mysql-bin.000018′, position 107

3、备份文件恢复
scp /tmp/data/mysql.tar.gz root@192.168.1.2:/tmp/
mkdir /tmp/mysql
cd /tmp/mysql
tar izxvf /tmp/mysql.tar.gz
–恢复数据库
innobackupex –apply-log –user=root –password=xifenfei /tmp/mysql
–复制到my.cnf中指定地方
innobackupex –copy-back –user=root –password=xifenfei /tmp/mysql
chmod -R mysql.mysql /var/lib/mysql

4、修改my.cnf文件
主服务器：
server-id=1
innodb_flush_log_at_trx_commit=1
sync-binlog=1

从服务器：
server-id=2
relay-log=/var/lib/mysql/replicate
relay-log-index=/var/lib/mysql/replicate.index
read-only

7、添加复制用户（主数据库上）
GRANT REPLICATION SLAVE ON *.*
TO ‘repl’@’192.168.1.2′ IDENTIFIED BY ‘xifenfei’;

8、配置从数据库
CHANGE MASTER TO
MASTER_HOST=’192.168.1.4′,
MASTER_USER=’repl’,
MASTER_PASSWORD=’xifenfei’,
MASTER_LOG_FILE=’mysql-bin.000018′,
MASTER_LOG_POS=107;
start slave;

9、查看主从是否正常
