若泽大数据测试平台MySQL环境搭建
一、介质需求：
本次安装MySQL5.6版本，目前MySQL已经更新到了8.0版
二、CentOS自带MySQL卸载：
CentOS6.5会自带MySQL的服务，组件，客户端等是之前5.1版本所遗留的，如不删除干净，会对以后使用的MySQL造成一定的BUG，所以我会先将之前的一些组件目录，配置文件等删除和卸载。
1、使用命令查看当前安装MySQL的情况：
[root@hadoop-01 /]# rpm -qa|grep -i mysql
mysql-libs-5.1.71-1.el6.x86_64
显示目前只装了 MySQL的libs包，其他Server和Client都没有安装
2、停止mysql服务、删除之前安装的MySQL
[root@hadoop-01 /]# rpm -e --nodeps mysql-libs-5.1.71-1.el6.x86_64
3、查找之前版本MySQL的目录、并且删除老版本MySQL的文件和库
[root@hadoop-01 /]# find / -name mysql
/usr/share/mysql
/usr/lib64/mysql
将查到的文件夹删除
[root@hadoop-01 /]# rm -rf /usr/share/mysql
[root@hadoop-01 /]# rm -rf /usr/lib64/mysql
4、注意/etc目录下会包含my.cnf文件，所以也需要删除
[root@hadoop-01 /]# rm -rf /etc/my.cnf
5、再次查找是否安装了MySQL
[root@hadoop-01 /]# rpm -qa|grep -i mysql
[root@hadoop-01 /]#
无显示，说明之前的环境彻底删除
三、MySQL5.6编译安装：
1、安装前的有关描述
必备的包和工具
gcc/g++ ：MySQL 5.6开始，需要使用g++进行编译。
cmake ：MySQL 5.5开始，使用cmake进行工程管理，cmake需要2.8以上版本。
bison ：MySQL语法解析器需要使用bison进行编译。
ncurses-devel ：用于终端操作的开发包。
zlib ：MySQL使用zlib进行压缩
功能需要的包
libxml ：用于XML输入输出方式的支持。
openssl ：使用openssl安全套接字方式通信。
dtrace ：用于诊断MySQL问题。
2、本次安装环境
[root@hadoop-01 /]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
MySQL版本：5.6.23-linux-glibc2.5-x86_64
安装目录为：/usr/local/mysql/
数据目录为：/data/mysqldata
存储引擎包括：MEMORY，MyISAM，InnoDB等
字符集为：UTF8
MySQL5.6版本需要先安装异步IO性能提升包
[root@hadoop-01 local]# rpm -qa|grep libaio
libaio-devel-0.3.107-10.el6.x86_64
libaio-0.3.107-10.el6.x86_64
[root@hadoop-01 local]# yum install libaio-0.3.107-10.el6.x86_64
1.Download
[root@hadoop-01 /]# cd /usr/local/
[root@hadoop-01 local]# rz
rz waiting to receive.
zmodem trl+C ȡ
100% 169210 KB 24172 KB/s 00:00:07 0 Errors.
100% 304464 KB 11276 KB/s 00:00:27 0 Errorsgz...
2.Check isnot install
[root@hadoop-01 local]# ps -ef | grep mysqld
root 3155 2830 0 01:45 pts/0 00:00:00 grep mysqld
[root@hadoop-01 local]# rpm -qa|grep -i mysql
[root@hadoop-01 local]#
3.tar and mv
[root@hadoop-01 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@hadoop-01 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql
4.Create group and user
[root@hadoop-01 local]# groupadd -g 101 dba
[root@hadoop-01 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
-g 是gid -G是root组 -d是家目录
[root@hadoop-01 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
生产环境: 给你的用户肯定不是root，给jepson/123456 (sudo/不带sudo)
sudo: 创建一个mysql服务的管理的用户
不 sudo: IT 给你的用户开启sudo权限
为什么要创建mysqladmin/dba？
1.一个用户只对一个组件
2.dba组
要postgresql，pgadmin/dba
#[root@sht-sgmhadoopnn-01 local]# passwd mysqladmin
Changing password for user mysqladmin.
New UNIX password:
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@sht-sgmhadoopnn-01 local]#
## if user mysqladmin is existing,please execute the following command of usermod.
#[root@sht-sgmhadoopnn-01 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin #
## copy 环境变量配置文件至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量
[root@hadoop-01 local]# cp /etc/skel/.* /usr/local/mysql
cp: omitting directory `/etc/skel/.'
cp: omitting directory `/etc/skel/..'
cp: omitting directory `/etc/skel/.gnome2'
cp: omitting directory `/etc/skel/.mozilla'
5.Create /etc/my.cnf(640)
#defualt start: /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h sht-sgmhadoopnn-01 password 'new-password'
Alternatively you can run:
./bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems at http://bugs.mysql.com/
The latest information about MySQL is available on the web at
http://www.mysql.com
Support MySQL by buying support/licenses at http://shop.mysql.com
New default config file was created as ./my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server
8.Configure mysql service and boot auto start
[root@sht-sgmhadoopnn-01 ~]# cd /usr/local/mysql
#将服务文件拷贝到init.d下，并重命名为mysql
[root@sht-sgmhadoopnn-01 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
#赋予可执行权限
[root@sht-sgmhadoopnn-01 mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql
#添加服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --add mysql
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --level 345 mysql on
9.Start mysql and to view process and listening
[root@sht-sgmhadoopnn-01 mysql]# su - mysqladmin

[root@hadoop-01 /]# find / -name mysql
/usr/share/mysql
/usr/lib64/mysql
将查到的文件夹删除
[root@hadoop-01 /]# rm -rf /usr/share/mysql
[root@hadoop-01 /]# rm -rf /usr/lib64/mysql
4、注意/etc目录下会包含my.cnf文件，所以也需要删除
[root@hadoop-01 /]# rm -rf /etc/my.cnf
5、再次查找是否安装了MySQL
[root@hadoop-01 /]# rpm -qa|grep -i mysql
[root@hadoop-01 /]#
无显示，说明之前的环境彻底删除
三、MySQL5.6编译安装：
1、安装前的有关描述
必备的包和工具
gcc/g++ ：MySQL 5.6开始，需要使用g++进行编译。
cmake ：MySQL 5.5开始，使用cmake进行工程管理，cmake需要2.8以上版本。
bison ：MySQL语法解析器需要使用bison进行编译。
ncurses-devel ：用于终端操作的开发包。
zlib ：MySQL使用zlib进行压缩
功能需要的包
libxml ：用于XML输入输出方式的支持。
openssl ：使用openssl安全套接字方式通信。
dtrace ：用于诊断MySQL问题。
2、本次安装环境
[root@hadoop-01 /]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
MySQL版本：5.6.23-linux-glibc2.5-x86_64
安装目录为：/usr/local/mysql/
数据目录为：/data/mysqldata
存储引擎包括：MEMORY，MyISAM，InnoDB等
字符集为：UTF8
MySQL5.6版本需要先安装异步IO性能提升包
[root@hadoop-01 local]# rpm -qa|grep libaio
libaio-devel-0.3.107-10.el6.x86_64
libaio-0.3.107-10.el6.x86_64
[root@hadoop-01 local]# yum install libaio-0.3.107-10.el6.x86_64
1.Download
[root@hadoop-01 /]# cd /usr/local/
[root@hadoop-01 local]# rz

2.Check isnot install
[root@hadoop-01 local]# ps -ef | grep mysqld
root 3155 2830 0 01:45 pts/0 00:00:00 grep mysqld
[root@hadoop-01 local]# rpm -qa|grep -i mysql
[root@hadoop-01 local]#
3.tar and mv
[root@hadoop-01 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@hadoop-01 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql
4.Create group and user
[root@hadoop-01 local]# groupadd -g 101 dba
[root@hadoop-01 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
-g 是gid -G是root组 -d是家目录
[root@hadoop-01 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
生产环境: 给你的用户肯定不是root，给jepson/123456 (sudo/不带sudo)
sudo: 创建一个mysql服务的管理的用户
不 sudo: IT 给你的用户开启sudo权限
为什么要创建mysqladmin/dba？
1.一个用户只对一个组件
2.dba组
要postgresql，pgadmin/dba
#[root@sht-sgmhadoopnn-01 local]# passwd mysqladmin
Changing password for user mysqladmin.
New UNIX password:
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@sht-sgmhadoopnn-01 local]#
## if user mysqladmin is existing,please execute the following command of usermod.
#[root@sht-sgmhadoopnn-01 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin #
## copy 环境变量配置文件至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量
[root@hadoop-01 local]# cp /etc/skel/.* /usr/local/mysql
cp: omitting directory `/etc/skel/.'
cp: omitting directory `/etc/skel/..'
cp: omitting directory `/etc/skel/.gnome2'
cp: omitting directory `/etc/skel/.mozilla'
5.Create /etc/my.cnf(640)
#defualt start: /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h sht-sgmhadoopnn-01 password 'new-password'
Alternatively you can run:
./bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems at http://bugs.mysql.com/
The latest information about MySQL is available on the web at
http://www.mysql.com
Support MySQL by buying support/licenses at http://shop.mysql.com
New default config file was created as ./my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server
8.Configure mysql service and boot auto start
[root@sht-sgmhadoopnn-01 ~]# cd /usr/local/mysql
#将服务文件拷贝到init.d下，并重命名为mysql
[root@sht-sgmhadoopnn-01 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
#赋予可执行权限
[root@sht-sgmhadoopnn-01 mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql
#添加服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --add mysql
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --level 345 mysql on
9.Start mysql and to view process and listening
[root@sht-sgmhadoopnn-01 mysql]# su - mysqladmin
