Cmake编译安装MySQL&mysqld_multi部署MySQL多实例方案

Cmake编译安装MySQL&mysqld_multi部署MySQL多实例方案

MySQL二进制包和源码包的区分

所有的操作根据实际情况而定

1.1准备安装环境

1.首先检查是否已经安装过mysql：

> rpm -qa | grep mysql

2.有的话就卸载掉以前安装的mysql：

> rpm -e --nodeps xxx（xxx是搜索结果）

3.并删除所有的相关文件：

> rm -f /etc/my.cnf

1.2下载cmake安装包编译安装cmake

1.下载解压Cmake

> wget  https://cmake.org/files/v3.9/cmake-3.9.1.tar.gz > tar zxf  cmake-3.9.1.tar.gz

2.编译安装cmake

> cd cmake-3.9.1
> ./configure
> gmake
> echo $?
4000
#编译但是未安装之前判断是否编译有错
> gmake install

1.3下载MySQL编译安装MySQL

1.安装依赖包

> yum -y install libaio libaio-devel
> yum -y install ncurses-devel

2.创建用户组 用户

> groupadd mysql
> useradd mysql -s /sbin/nologin -M -g mysql

3.下载解压

> wget https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.57.tar.gz > tar -zxf mysql-5.5.57.tar.gz

4.cmake编译安装(编译时不能指定配置文件端口号mysql.sock地址等)

> cd mysql-5.5.57
> cmake \-DCMAKE_INSTALL_PREFIX=/usr/local/mysql5.5.57 -DMYSQL_UNIX_ADDR=/usr/local/mysql/tmp/mysql.sock -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc/my.cnf  -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all
> make && make install

5.检查是否安装成功

> echo $?
> 0
#（输出0表示成功）

6.设置软链接及配置文件

> ln -s /usr/local/mysql55 /usr/local/mysql

1.4配置MySQL多实例(mysqld_multi方式)

1.创建多实例数据目录

> mkdir -pv /data/mysql/{3306,3307}

2.设置访问权限

> chown -R mysql:mysql /data/mysql

3.初始化数据库

> cd /usr/local/mysql/scripts/
> ./mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/3306 --user=mysql
> ./mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/3307 --user=mysql

4.修改配置文件（注意路径和端口号）

[mysqld_multi]
mysqld=/usr/local/mysql/bin/mysqld_safe
mysqladmin=/usr/local/mysql/bin/mysqladmin
user=multi_admin
password=multi_password

datadir=/data/mysql/data3306

[mysqld3307]

[mysqld_multi]
mysqld = /usr/local/mysql/bin/mysqld_safe

5.通过bin下的工具mysqld_multi管理MySQL的多实例

#启动
> /usr/local/mysql/bin/mysqld_multi start
> /usr/local/mysql/bin/mysqld_multi start 1-2
> /usr/local/mysql/bin/mysqld_multi start 1
#可查看运行状态
> /usr/local/mysql/bin/mysqld_multi report
#关闭
> /usr/local/mysql/bin/mysqld_multi stop
> /usr/local/mysql/bin/mysqld_multi stop 1-2
> /usr/local/mysql/bin/mysqld_multi stop 1

6.检查是否启动成功

> ps -ef | grep mysqld
#或者
> netstat -anp | grep 3306

7.连接数据库

1. 指定ip 端口号进入
> mysql -u root -h 127.0.0.1 -P 3306
2. 指定socket登陆，适合在本机连接
> mysql -u root -p -S /tmp/3306.sock
3. 输入密码即可进入

8.初始化密码并且授权远程登录

> /usr/local/mysql/bin/mysqladmin -u root password "yourpassword" -S /tmp/3306.sock
> /usr/local/mysql/bin/mysql -uroot -p -S /tmp/3306.sock
#输入密码进入
mysql> grant all privileges on *.* to 'root'@'%' identified by '3306password' with grant option;
mysql> flush privileges;
