1.Download and Check MD5
[root@sht-sgmhadoopnn-01 ~]# cd /usr/local
[root@sht-sgmhadoopnn-01 local]# wget https://downloads.mariadb.com/archives/mysql-5.6/mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@sht-sgmhadoopnn-01 local]# wget https://downloads.mariadb.com/archives/mysql-5.6/mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz.md5
（weget下载安装包网址已失效 使用weget下载的时候中间有可能丢包）
自备mysql装装包
mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
选择rz上传
[root@sht-sgmhadoopnn-01 local]# cat mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz.md5
61affe944eff55fcf51b31e67f25dc10 mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@sht-sgmhadoopnn-01 local]# md5sum mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
61affe944eff55fcf51b31e67f25dc10 mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
当在weget下载的安装包有md5一定要校验一下mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz.md5和
md5sum mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz之间的区别
2.Check isnot install
[root@sht-sgmhadoopnn-01 local]# ps -ef|grep mysqld
root 2493 2423 0 19:48 pts/3 00:00:00 grep mysqld
[root@sht-sgmhadoopnn-01 local]# rpm -qa |grep -i mysql
3.tar and mv
[root@sht-sgmhadoopnn-01 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@sht-sgmhadoopnn-01 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql
4.Create group and user
[root@sht-sgmhadoopnn-01 local]# groupadd -g 101 dba
[root@sht-sgmhadoopnn-01 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
useradd: warning: the home directory already exists.
Not copying any file from skel directory into it.
[root@hadoop001 local]#
[root@sht-sgmhadoopnn-01 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
[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@sht-sgmhadoopnn-01 local]# cp /etc/skel/.* /usr/local/mysql
cp: omitting directory `/etc/skel/.'
cp: omitting directory `/etc/skel/..'
cp: omitting directory `/etc/skel/.mozilla'
对于一个系统想要运行 肯定需要配置文件 my.cnf
5.Create /etc/my.cnf (640权限)
#defualt start: /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf
->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf
[root@sht-sgmhadoopnn-01 mysql]# cd /etc/

6.chown and chmod privileges and try first install

[root@sht-sgmhadoopnn-01 etc]# ll my.cnf

[root@sht-sgmhadoopnn-01 local]# chmod -R 755 /usr/local/mysql
[root@sht-sgmhadoopnn-01 local]# su - mysqladmin
[mysqladmin@sht-sgmhadoopnn-01 ~]$ pwd

#创建arch目录 存储binlog 归档日志 mysql--maxwell--kafka--ss--hbase 实时 mcp
[mysqladmin@sht-sgmhadoopnn-01 ~]$ mkdir arch

###see version
[root@sht-sgmhadoopnn-01 local]# cat /proc/version

7.Again install
[mysqladmin@sht-sgmhadoopnn-01 ~]$ scripts/mysql_install_db
--user=mysqladmin
--basedir=/usr/local/mysql
--datadir=/usr/local/mysql/data
查看data/hostname.err文件 仔细错误
8.Configure mysql service and boot auto start（mysql部署开机自启动）
[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 --为了部署开机自启动服务
[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 ---如果之前有这个服务先给删除掉（不管有没有都执行一下，以防万一）
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql
#添加服务 --重新添加服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --add mysql
#设置开机自启动，level级别345=on
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --level 345 mysql on
#有时候上边那一步不能真正的做到开机自启动，还需要一下的操作
[root@sht-sgmhadoopnn-01 mysql]# vi /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
su - mysqladmin -c "/etc/init.d/mysql start --federated"
9.Start mysql and to view process and listening
[root@sht-sgmhadoopnn-01 mysql]# su - mysqladmin
[mysqladmin@sht-sgmhadoopnn-01 ~]$ pwd
/usr/local/mysql
[mysqladmin@sht-sgmhadoopnn-01 ~]$ rm -rf my.cnf my-new.cnf --放着也没有关系 这个文件是在创建家目录时自动创建的
[mysqladmin@hadoop001 ~]$ service mysql start
Starting MySQL. [ OK ]
[mysqladmin@hadoop001 ~]$
[mysqladmin@hadoop001 ~]$ service mysql status
MySQL running (3625) [ OK ]
[mysqladmin@hadoop001 ~]$
[mysqladmin@sht-sgmhadoopnn-01 ~]$ mysqld_safe & --启动mysql 也可以用service mysql start命令开启 &这个符号是后台执行的意思 执行玩这个命令以后光标一直在跳动 一定要按一次回车键

will not be shown, you would have to be root to see it all.)

[root@sht-sgmhadoopnn-01 local]# service mysql status --service这个命令也能用的原因是我们已经部署了init.d,机器会在这个命令下去找mysql这个命令
MySQL running (21507) [ OK ]
部署完成了
创建一个root用户 密码为空
一个空用户 密码为空
生产上密码肯定不为空 比如123456
bin/mysql -uroot -p -h127.0.0.1 一回城就让你输入密码 这是安全的 不会被history记录
bin/mysql -uroot -p123456 -h127.0.0.1 一回城就进数据库 这是不安全的 会被history记录
bin/mysql -u root -p 123456 -h 127.0.0.1 -P3306
10.Login mysql
[mysqladmin@sht-sgmhadoopnn-01 ~]$ mysql

test2.localdomain:mysqladmin:/usr/local/mysql/arch:>chmod 755 *
test2.localdomain:mysqladmin:/usr/local/mysql/arch:>chown –R mysqladmin:dba *
注意以后要是想重新部署mysql那就把家目录下的data和arch这俩个目录下的内容删除干净。
hadoop001:mysqladmin:/usr/local/mysql/arch:>rm -rf arch/*
hadoop001:mysqladmin:/usr/local/mysql/arch:>rm -rf data/*
删除完成以后就可以重新部署
