MySQL多实例安装

1、配置3306实例

1.1、查询服务器上是否已经安装的mysql

[root@masterMySQL-5.6.25-1.el6.x86_64.rpm-bundle]# rpm -aq | grep mysql

mysql-server-5.1.66-2.el6_3.x86_64

mysql-libs-5.1.66-2.el6_3.x86_64

mysql-devel-5.1.66-2.el6_3.x86_64

qt-mysql-4.6.2-25.el6.x86_64

mysql-5.1.66-2.el6_3.x86_64

1.2、先卸载旧的版本

rpm -e mysql --nodeps --allmatches(不理会依赖关系，删除所有上一步查出来的mysql)

[root@master ~]#rpm -e mysql-server-5.1.66-2.el6_3.x86_64 --nodeps --allmatches

[root@master ~]#rpm -e mysql-libs-5.1.66-2.el6_3.x86_64 --nodeps --allmatches

[root@master ~]#rpm -e mysql-devel-5.1.66-2.el6_3.x86_64 --nodeps --allmatches

[root@master ~]#rpm -e qt-mysql-4.6.2-25.el6.x86_64 --nodeps --allmatches

[root@master ~]#rpm -e mysql --nodeps --allmatches

[root@master ~]#rpm -aq | grep mysql

1.3、安装软件

# rpm -ivfMySQL-server-5.6.25-1.el6.x86_64.rpm  #MySQL服务端程序

# rpm -ivfMySQL-client-5.6.25-1.el6.x86_64.rpm  #MySQL客户端程序

# rpm -ivfMySQL-devel-5.6.25-1.el6.x86_64.rpm   #MySQL的库和头文件

# rpm -ivfMySQL-shared-5.6.25-1.el6.x86_64.rpm  #MySQL的共享库

# rpm -ivfMySQL-shared-compat-5.6.25-1.el6.x86_64.rpm #RHEL兼容包

1.4、修改密码

#/etc/init.d/mysql stop

# mysqld_safe--skip-grant-tables &

# mysql-uroot  -e "use mysql;update userset password=password('123456') where user='root' and host='localhost';";

# mysql-uroot  -e"use mysql;update user sethost='%'  where user='root'  and host='localhost';flush privileges;";

1.5、修改配置文件

[root@mastermysql]#service mysql stop

[root@mastermysql]# vi /usr/my.cnf

[client]

default-character-set=utf8

port =3306

socket =/var/lib/mysql/mysql.sock

max_allowed_packet= 32M

[mysqld_safe]

log-error=/var/lib/mysql/mysql_master.err

pid-file=/var/lib/mysql/mysqld.pid

service mysqlstart

2、配置3307实例

2.1、建立3307目录存放数据：

[root@master ~]#mkdir /data/3307/mysql -p

[root@master ~]#cd /

[root@master /]#chown -R mysql.mysql data

[root@master /]#cd /data/3307/mysql

2.2、建立3307配置文件：

vi my.cnf

[client]

default-character-set=utf8

port = 3307

socket = /data/3307/mysql.sock

[mysql]

no-auto-rehash

[mysqld]

character-set-server=utf8

user = mysql

port = 3307

socket = /data/3307/mysql.sock

basedir = /usr

datadir = /data/3307/mysql

binlog_format=mixed

open_files_limit    = 10240

sync_binlog = 1

back_log = 600

max_connections = 3000

max_connect_errors = 6000

#table_cache = 614

external-locking = FALSE

max_allowed_packet = 32M

sort_buffer_size = 2M

join_buffer_size = 2M

thread_cache_size = 300

thread_concurrency = 8

query_cache_size = 64M

query_cache_limit = 4M

query_cache_min_res_unit = 2k

#default_table_type = InnoDB

thread_stack = 192K

transaction_isolation = READ-COMMITTED

tmp_table_size = 256M

max_heap_table_size = 256M

long_query_time = 1

slow_query_log=1

slow_query_log_file =/data/3307/mysql/mysql_slow_query.log

#log_long_format

log-error=/data/3307/mysql/error.log

#log-slow-queries=/data/3307/mysql/slow-log.log

pid-file=/data/3307/mysql/mysql.pid

log-bin = /data/3307/mysql/mysql-bin

relay-log=/data/3307/mysql/relay-bin

relay-log-info-file=/data/3307/mysql/relay-log.info

binlog_cache_size = 4M

max_binlog_cache_size = 50M

max_binlog_size = 512M

expire_logs_days = 7

key_buffer_size = 32M

read_buffer_size = 1M

read_rnd_buffer_size = 16M

bulk_insert_buffer_size = 64M

myisam_sort_buffer_size = 128M

innodb_additional_mem_pool_size = 16M

innodb_buffer_pool_size = 2048M

#innodb_data_file_path =ibdata1:1024M:autoextend

innodb_file_io_threads = 4

innodb_thread_concurrency = 8

innodb_flush_log_at_trx_commit = 1

innodb_log_buffer_size = 16M

innodb_log_file_size = 1024M

innodb_log_files_in_group = 3

innodb_max_dirty_pages_pct = 90

innodb_lock_wait_timeout = 120

innodb_file_per_table = 0

[mysqldump]

quick

max_allowed_packet = 32M

[mysqld_safe]

log-error=/data/3307/mysql/mysql_master.err

pid-file=/data/3307/mysql/mysqld.pid

修改配置参数的权限

[root@mastermysql]# chown mysql.mysql my.cnf

[root@mastermysql]# /usr/bin/mysql_install_db --defaults-file=/data/3307/mysql/my.cnf--user=mysql --basedir=/usr --datadir=/data/3307/mysql/

[root@mastermysql]# /usr/bin/mysqld_safe --defaults-file=/data/3307/mysql/my.cnf--user=mysql --basedir=/usr --datadir=/data/3307/mysql/ &

2.3、查看端口号：

netstat -nat|grep 330

2.4、修改密码：

mysqladmin-uroot password '123456' -S /data/3307/mysql.sock
