分类目录归档：MySQL安装配置

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]
port = 3306
socket = /var/run/mysqld/mysqld.sock
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
basedir = /opt/mysql/product/5.5
datadir = /opt/mysql/mysqldata
skip-external-locking = 1
interactive_timeout = 1200
wait_timeout = 1200
character-set-server = utf8
back_log = 500
default_time_zone = '+08:00'
max_connections = 1000
max_connect_errors = 1000
connect_timeout = 300
table_open_cache = 100
max_allowed_packet = 16M
binlog_cache_size = 8M
max_heap_table_size = 64M
sort_buffer_size = 8M
join_buffer_size = 8M
thread_cache_size = 32
thread_concurrency = 16
query_cache_size = 0M
default-storage-engine = INNODB
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 64M
log-bin =/opt/mysql/mysqllog/mysqlbin
log-error=/opt/mysql/mysqllog/mysqld.err
expire_logs_days = 7
binlog_format = ROW
max_binlog_size = 300M
slow_query_log = 1
slow_query_log_file =/opt/mysql/mysqllog/mysqld-slow
long_query_time = 10
tmpdir = /tmp
server-id = 1
key_buffer_size = 8M
read_buffer_size = 1M
read_rnd_buffer_size = 1M
bulk_insert_buffer_size = 1M
myisam_sort_buffer_size = 128K
innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 2G
innodb_data_file_path = ibdata1:1024M:autoextend
innodb_autoextend_increment = 64
innodb_file_per_table = 1
innodb_data_home_dir = /opt/mysql/mysqldata
innodb_file_io_threads = 4
innodb_thread_concurrency = 16
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 8M
innodb_log_file_size = 512M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 40
innodb_lock_wait_timeout = 120
innodb_locks_unsafe_for_binlog = 1
innodb_autoinc_lock_mode = 2
skip-name-resolve
lower_case_table_names=1
[mysqldump]
quick
max_allowed_packet = 16M
[mysql]
auto-rehash
[myisamchk]
key_buffer_size = 512M
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

一、整体规划
192.168.11.10（ndb）
192.168.11.11（ndb）
192.168.11.12（mgm）
192.168.11.13（sql）
192.168.11.14（sql）

二、安装mysql-cluster软件(root)
所有节点相同操作，如果没有mysql用户请创建mysql用户和组
groupadd mysql
useradd -g mysql mysql

上传至/tmp目录，开始解压安装
cd/tmp
tarxzvftarxzvfmysql-cluster-gpl-7.1.15-linux-x86_64-glibc23.tar.gz
mvmysql-cluster-gpl-7.1.15-linux-x86_64-glibc23/opt/mysql_cluster
chownmysql.mysql-R/opt/mysql_cluster

三、管理节点（mgm）配置(mysql)
配置mgm节点的config.ini文件
[NDBDDEFAULT]
NoOfReplicas=2
[NDB_MGMD]
NodeId=1
hostname=192.168.11.12
[NDBD]
NodeId=11
hostname=192.168.11.11
datadir=/opt/mysql_cluster/ndbdata
[NDBD]
NodeId=12
hostname=192.168.11.10
datadir=/opt/mysql_cluster/ndbdata
[MYSQLD]
NodeId=21
hostname=192.168.11.13
[MYSQLD]
NodeId=22
hostname=192.168.11.14

启动mgm节点
/opt/mysql_cluster/bin/ndb_mgmd -f /opt/mysql_cluster/config.ini –configdir=/opt/mysql_cluster

四、数据节点配置(mysql)
配置ndb节点参数(/opt/mysql_cluster/my.cnf)
[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]
ndb-connectstring=192.168.11.12

修改mysql.server(mysql)
/opt/mysql_cluster/support-files/mysql.server中的datadir和basedir为
basedir=/opt/mysql_cluster
datadir=/opt/mysql_cluster/data

启动sql节点(mysql)
/opt/mysql_cluster/support-files/mysql.server start

六、查看集群状态(msyql)
ndb_mgm> show
Connected to Management Server at: localhost:1186
Cluster Configuration
———————
[ndbd(NDB)] 2 node(s)
id=11 @192.168.11.11 (mysql-5.1.56 ndb-7.1.15, Nodegroup: 0, Master)
id=12 @192.168.11.10 (mysql-5.1.56 ndb-7.1.15, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)

id=22 @192.168.11.14 (mysql-5.1.56 ndb-7.1.15)

mysql 集群配置（windows2台机器模拟）
1、环境规划
win7 192.168.1.1（管理节点，存储节点，sql节点）
win03 192.168.1.2（存储节点，sql节点）

2、安装cluster（zip包）
win7机器安装在D:\mysql-cluster中
win03机器安装在C:\mysql-cluster中
存储节点存储路径分别为：D:\mysql-cluster\ndbdata和C:\mysql-cluster\ndbdata

3、win7机器配置
创建D:\mysql-cluster\config.txt文件，内容为：
[NDBD DEFAULT]
NoOfReplicas=2
[NDB_MGMD]
ID=1
hostname=192.168.1.1
datadir=D:\mysql-cluster\data
[NDBD]
ID=21
hostname=192.168.1.1
datadir=D:\mysql-cluster\ndbdata
[NDBD]
ID=22
hostname=192.168.1.2
datadir=C:\mysql-cluster\ndbdata
[MYSQLD]
ID=11
hostname=192.168.1.1
[MYSQLD]
ID=12
hostname=192.168.1.2

复制D:\mysql-cluster\my-small.ini到c:\windows\my.ini并添加
[mysqld]
ndbcluster
ndb-connectstring=192.168.1.1
[mysql_cluster]
ndb-connectstring=192.168.1.1

4、win03机器配置
复制C:\mysql-cluster\my-small.ini到c:\windows\my.ini并添加
[mysqld]
ndbcluster
ndb-connectstring=192.168.1.1
[mysql_cluster]
ndb-connectstring=192.168.1.1

5、启动
5.1）启动管理节点(win7 上)
D:\mysql-cluster\bin>ndb_mgmd.exe –config-file=D:\mysql-cluster\config.txt –co
nfigdir=D:\mysql-cluster

5.2）启动存储节点（无先后顺序，第一个启动使用–initial)
win7
D:\mysql-cluster\bin>ndbd.exe –initial
win03
C:\mysql-cluster\bin>ndbd.exe

5.3）启动sql节点（无先后顺序）
win03
C:\mysql-cluster\bin>mysqld.exe –defaults-file=c:\windows\my.ini
win7
d:\mysql-cluster\bin>mysqld.exe –defaults-file=c:\windows\my.ini

6、查看是否启动成功
6.1）查看状态
D:\mysql-cluster\bin>ndb_mgm.exe
– NDB Cluster — Management Client –
ndb_mgm> show
