三、安装配置多实例MYSQL5.6-多独立配置文件方法

1、准备工作

检查操作系统版本、内核版本、selinux是否关闭、防火墙策略、IP地址、主机名配置、host表配置、yum配置

上传cmake、mysql5.6软件包

具体步骤参考源码安装mysql-单实例配置文档

2、安装cmake软件

2.1 安装编译软件环境

[[email protected] ~]# yum -y install gcc-c++ncurses-devel make perl bison ncurses

2.2 解压软件包

[[email protected] ~]# cd /opt/software/

[[email protected] software]# tar -zxfcmake-3.0.1.tar.gz

2.3 编译安装

[[email protected] cmake-3.0.1]# pwd

/opt/software/cmake-3.0.1

[[email protected] cmake-3.0.1]# ./bootstrap

[[email protected] cmake-3.0.1]# gmake&& make install

2.4 校验安装是否成功

[[email protected] ~]# cmake --version

[[email protected] cmake-3.0.1]# cmake --version

cmake version 3.0.1

3、安装mysql

3.1 创建mysql用户、用户组

[[email protected] cmake-3.0.1]# useradd mysql-s ‘/sbin/nologin‘ -r –M //-r创建系统用户，-M不创建home目录

[[email protected] cmake-3.0.1]# id mysql

uid=498(mysql) gid=498(mysql)groups=498(mysql)

3.2 创建mysql安装目录

[[email protected] ~]# mkdir /usr/local/mysql

3.3 创建mysql数据目录

[[email protected] ~]# mkdir -pv/home/mysql/data{3306,3307}

mkdir: created directory `/home/mysql‘

mkdir: created directory`/home/mysql/data3306‘

mkdir: created directory`/home/mysql/data3307‘

[[email protected] ~]# tree /home/mysql/

/home/mysql/

├── data3306

└── data3307

2 directories, 0 files

3.5 编译安装mysql5.6

[[email protected] ~]# cd /opt/software

[[email protected] software]# tar -zxfmysql-5.6.16.tar.gz

[[email protected] software]# cd mysql-5.6.16

[[email protected] mysql-5.6.16]# cmake \

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

-DMYSQL_DATADIR=/home/mysql/ \

-DSYSCONFDIR=/etc \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_ARCHIVE_STORAGE_ENGINE=1 \

-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_PARTITION_STORAGE_ENGINE=1 \

-DEXTRA_CHARSETS=all \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk

[[email protected] mysql-5.6.16]# make&& make install

4、配置3306数据库主配置文件

[[email protected] ~]# cd /home/mysql/data3306

[[email protected] data3306]# vim my.cnf

[client]

socket = /home/mysql/data3306/mysqld.sock

port = 3306

[mysqld]

basedir =/usr/local/mysql

datadir =/home/mysql/data3306

socket = /home/mysql/data3306/mysqld.sock

port =3306

server_id =1

user = mysql

join_buffer_size = 128M

sort_buffer_size = 2M

read_rnd_buffer_size = 2M

default_storage_engine = InnoDB

join_buffer_size = 128M

max_allowed_packet= 1M

net_buffer_length= 8K

skip-external-locking

skip-host-cache

skip-name-resolve

# InnoDB

innodb_buffer_pool_size = 128M

innodb_log_file_size = 48M

innodb_file_per_table = 1

innodb_flush_method = O_DIRECT

# MyISAM

key_buffer_size = 48M

character-set-server=utf8

collation-server=utf8_general_ci

# LOG

log_error = /home/mysql/data3306/mysql-error.log

long_query_time = 1

slow-query-log

slow_query_log_file = /home/mysql/data3306/mysql-slow.log

# Others

explicit_defaults_for_timestamp=true

max_connections = 500

open_files_limit = 65535

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

5、配置3307数据库主配置文件

[[email protected] data3306]# cp my.cnf../data3307/

[[email protected] data3306]# sed -i‘s/3306/3307/g‘ ../data3307/my.cnf

[[email protected] data3306]# vim../data3307/my.cnf

server_id =2

[[email protected] data3306]# cat ../data3307/my.cnf

[client]

socket =/home/mysql/data3307/mysqld.sock

port =3307

[mysqld]

basedir =/usr/local/mysql

datadir =/home/mysql/data3307

socket = /home/mysql/data3307/mysqld.sock

port =3307

server_id =2

user = mysql

join_buffer_size = 128M

sort_buffer_size = 2M

read_rnd_buffer_size = 2M

default_storage_engine = InnoDB

join_buffer_size = 128M

max_allowed_packet= 1M

net_buffer_length= 8K

skip-external-locking

skip-host-cache

skip-name-resolve

# InnoDB

innodb_buffer_pool_size = 128M

innodb_log_file_size = 48M

innodb_file_per_table = 1

innodb_flush_method = O_DIRECT

# MyISAM

key_buffer_size = 48M

character-set-server=utf8

collation-server=utf8_general_ci

# LOG

log_error = /home/mysql/data3307/mysql-error.log

long_query_time = 1

slow-query-log

slow_query_log_file = /home/mysql/data3307/mysql-slow.log

# Others

explicit_defaults_for_timestamp=true

max_connections = 500

open_files_limit = 65535

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

6、改变数据目录的属主

[[email protected] ~]# chown -R mysql.mysql/home/mysql/data330{6,7}

[[email protected] ~]# ls -ld /home/mysql/data330{6,7}

drwxr-xr-x 2 mysql mysql 4096 Nov  6 18:54 /home/mysql/data3306

drwxr-xr-x 2 mysql mysql 4096 Nov  6 18:54 /home/mysql/data3307

7、配置环境变量

/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

[[email protected] ~]# echo ‘exportPATH=/usr/local/mysql/bin:$PATH‘ >> /etc/profile

[[email protected] ~]# tail -1 /etc/profile

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

[[email protected] ~]# source /etc/profile

/usr/local/mysql/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

8、初始化MYSQL多实例数据库文件

/usr/local/mysql/scripts

[[email protected] scripts]# ./mysql_install_db--basedir=/usr/local/mysql --datadir=/home/mysql/data3306 --user=mysql

[[email protected] scripts]# ./mysql_install_db--basedir=/usr/local/mysql --datadir=/home/mysql/data3307 --user=mysql

9、启动MYSQL多实例数据库

[[email protected] ~]# mysqld_safe--defaults-file=/home/mysql/data3306/my.cnf 2>&1 > /dev/null &

[[email protected] ~]# mysqld_safe --defaults-file=/home/mysql/data3307/my.cnf2>&1 > /dev/null &

10、设置密码登录

[[email protected] ~]# mysqladmin -S/home/mysql/data3306/mysqld.sock -uroot password ‘123456‘

[[email protected] ~]# mysqladmin -S/home/mysql/data3307/mysqld.sock -uroot password ‘123456‘

11、登录实例，并删除test库及空密码账户

[[email protected] ~]# mysql  -S /home/mysql/data3306/mysqld.sock -uroot -p

Enter password:

mysql> status;

mysql> show databases;

mysql> drop database test;

mysql> use mysql;

mysql> select user,host,password fromuser;

mysql> delete from  user where password=‘‘;

mysql> flush privileges;

12、停库

[[email protected] ~]# mysqladmin shutdown -S/home/mysql/data3306/mysqld.sock -u root -p

Enter password:

[[email protected] ~]# mysqladmin shutdown -S/home/mysql/data3307/mysqld.sock -u root -p

Enter password:

[[email protected] ~]# ps -ef|grep mysqld|grep-v grep

[[email protected] ~]# netstat -tunlp|grep 330
