mysql5.6源码安装两个实例--模拟生产库

源码方式---安装两个实例（mysql5.6.40&CentOS6.8）----------生产库
mysql源码包：mysql-5.6.40.tar.gz

安装相关软件（前提条件是yum已正常使用）
# yum -y install make cmake gcc gcc-c++  bison-devel ncurses-devel libaio libaio-devel perl-Data-Dumper net-tools

停用系统防火墙和selinux
# service iptables stop
# service ip6tables stop
# chkconfig iptables off
# chkconfig ip6tables off
# vi /etc/selinux/config
将SELINUX=enforcing这个值改为SELINUX=disabled

创建用户和组
# groupadd mysql
# useradd -g mysql mysql

创建目录
目录说明：
软件目录：/u01/svr/mysql5.6
数据库目录：/u01/mydata/{my3306,my3307}
log目录：/u01/logs
配置文件目录：/u01/conf

mkdir -p /u01/{svr,logs,conf,mydata,tmp,run}
mkdir -p /u01/svr/mysql5.6
mkdir -p /u01/mydata/{my3306,my3307}
mkdir -p /u01/logs/{my3306,my3307}/{binlog,iblog}
mkdir -p /u01/tmp/{my3306,my3307}
chown -R mysql:mysql /u01/
chmod -R 755 /u01/

查看是否安装了mysql
# rpm -qa|grep mysql -i
如果存在需要卸载，不然下面的安装有可能会冲突
# rpm -e --nodeps xxx    (xxx搜索的结果)

上传源码安装包到/u01下并解压到前目录：tar -zxvf /u01/mysql-5.6.40.tar.gz

cd /u01//mysql-5.6.40

预编译

# cmake \
-DCMAKE_INSTALL_PREFIX=/u01/svr/mysql5.6 \
-DMYSQL_DATADIR=/u01/mydata/my3306 \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=/u01/run/mysql3306.sock \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci

执行完后最后会有下面的信息
strict-aliasing -DDBUG_OFF
-- Configuring done
-- Generating done
CMake Warning:
  Manually-specified variables were not used by the project:
    WITH_MEMORY_STORAGE_ENGINE
    WITH_READLINE
-- Build files have been written to: /home/temp/mysql-5.6.40

然后进行编译
# make && make install

因编译后有些文件的权限是root的，需要重新授权
chown -R mysql:mysql /u01/
chmod -R 755 /u01/

[mysqld_safe]
datadir=/u01/mydata/my3307/

注：两个实例的server_id不能一样！！

初始化3306数据库
# cd /u01/svr/mysql5.6/scripts
# ./mysql_install_db --basedir=/u01/svr/mysql5.6 --datadir=/u01/mydata/my3306 --defaults-file=/u01/conf/my3306.cnf

初始化3307数据库
# cd /u01/svr/mysql5.6/scripts
# ./mysql_install_db --basedir=/u01/svr/mysql5.6 --datadir=/u01/mydata/my3307 --defaults-file=/u01/conf/my3307.cnf

查看
/u01/logs/my3306/erro.log和/u01/logs/my3307/erro.log
是否有报错信息，重点查看erro关键词，如没有证明成功安装。

如果报错，需要把data和log新生成的文件删除再重新执行初始化

设置环境变量
在PATH=$PATH:$HOME/bin添加参数:/u01/svr/mysql5.6/bin:/u01/svr/mysql5.6l/lib
$ vi /home/mysql/.bash_profile
PATH=$PATH:$HOME/bin:/u01/svr/mysql5.6/bin:/u01/svr/mysql5.6l/lib

$ source /home/mysql/.bash_profile

接下来就是启动、使用、关闭mysql两个实例，创建sh文件夹存放sh脚本
$ mkdir /u01/sh
注：多个实例，建议分开启动，这样便于管理
创建启动脚本
$ vi /u01/sh/start3306.sh
#!/bin/bash
mysqld_safe --defaults-file=/u01/conf/my3306.cnf --socket=/u01/run/mysql3306.sock &
$ vi /u01/sh/start3307.sh
#!/bin/bash
mysqld_safe --defaults-file=/u01/conf/my3307.cnf --socket=/u01/run/mysql3307.sock &
授权
$ chmod +x *.sh

启动和查看进程
$ ps -ef|grep mysql
注意是否有/bin/sh /u01/svr/mysql5.6/bin/mysqld_safe和/u01/svr/mysql5.6/bin/mysqld这两种进程，每个实例有两个进程
注： 建议使用mysqld_safe启动mysql，mysqld_safe会一直监控着，如果mysqld服务异常的关闭了，mysqld_safe会自动启动mysqld服务

修改密码
登录脚本有可能需要修改root用户后才正常，启动服务后，更改root密码
$ mysql
mysql> update mysql.user set Password = password('新密码') where User='root';
如：update mysql.user set Password = password('root') where User='root';
mysql> flush privileges;

创建登录mysql脚本
$ vi /u01/sh/m6
#!/bin/bash
mysql --socket=/u01/run/mysql3306.sock --port=3306 -p
$ vi /u01/sh/m7
#!/bin/bash
mysql --socket=/u01/run/mysql3307.sock --port=3307 -p
授权
$ chmod +x *

创建关闭脚本
$ vi /u01/sh/shutdown3306.sh
#!/bin/bash
mysqladmin --socket=/u01/run/mysql3306.sock --port=3306 shutdown -p
$ vi /u01/sh/shutdown3307.sh
#!/bin/bash
mysqladmin --socket=/u01/run/mysql3307.sock --port=3307 -p shutdown -p
授权
$ chmod +x *.sh

//为root添加远程连接的能力。
mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "新密码";
