企业级mysql完美安装

1、将提前准备好的压缩包解压到 /usr/local（不用创建，已经存在的）
tar xzvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz -C /usr/local
2、换一个文件名
mv mysql-5.7.11-linux-glibc2.5-x86_64 mysql
3、创建一个目录
mkdir mysql/arch mysql/data mysql/tmp
4、创建my.cnf(见文件)
vi /etc/my.cnf
[client]
port = 3306
socket = /usr/local/mysql/data/mysql.sock
default-character-set=utf8mb4

[mysqld]
port            = 3306
socket          = /usr/local/mysql/data/mysql.sock

5、创建用户组及用户
groupadd -g 101 dba
useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
## 一般不需要设置mysqladmin的密码，直接从root或者LDAP用户sudo切换
#[root@hadoop39 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.
## if user mysqladmin is existing,please execute the following command of usermod.
#[root@hadoop39 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
6.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
cp /etc/skel/.* /usr/local/mysql ###important
7.配置环境变量
vi mysql/.bash_profile
# .bash_profile
# Get the aliases and functions

	if [ -f ~/.bashrc ]; then
	        . ~/.bashrc
	fi
	
	# User specific environment and startup programs
	export MYSQL_BASE=/usr/local/mysql
	export PATH=${MYSQL_BASE}/bin:$PATH
	unset USERNAME
	#stty erase ^H
	set umask to 022
	umask 022
	PS1=`uname -n`":"'$USER'":"'$PWD'":>"; export PS1
	## end

8.赋权限和用户组，切换用户mysqladmin，安装
chown mysqladmin:dba /etc/my.cnf
chmod 640 /etc/my.cnf
chown -R mysqladmin:dba /usr/local/mysql
chmod -R 755 /usr/local/mysql
9、配置服务及开机自启动
cd /usr/local/mysql
#将服务文件拷贝到init.d下，并重命名为mysql
cp support-files/mysql.server /etc/rc.d/init.d/mysql
#赋予可执行权限
chmod +x /etc/rc.d/init.d/mysql
#删除服务
chkconfig --del mysql
#添加服务
chkconfig --add mysql
chkconfig --level 345 mysql on
#还需要做一个动作：
vi /etc/rc.local
加入一句话：
su - mysqladmin -c “/etc/init.d/mysql start --federated”
10、安装libaio及安装mysql的初始db
yum -y install libaio
sudo su - mysqladmin

	/usr/local/mysql:> bin/mysqld \
	--defaults-file=/etc/my.cnf \
	--user=mysqladmin \
	--basedir=/usr/local/mysql/ \
	--datadir=/usr/local/mysql/data/ \
	--initialize
	在初始化时如果加上 –initial-insecure，则会创建空密码的 root@localhost 账号，否则会创建带密码的 					root@localhost 账号，密码直接写在 log-error 日志文件中

（在5.6版本中是放在 ~/.mysql_secret 文件里，更加隐蔽，不熟悉的话可能会无所适从）
11、查看临时密码
cat hostname.err |grep password
2017-07-22T02:15:29.439671Z 1 [Note] A temporary password is generated for root@localhost: kFCqrXeh2y(0
12、启动
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
13、登录及修改用户密码
:>mysql -uroot -p’kFCqrXeh2y(0’
mysql: [Warning] Using a password on the command line interface can be insecure.

	mysql> flush privileges;

	mysql> exit;
	Bye

14、重启
> service mysql restart

	:>mysql -uroot -pruozedata

重新部署怎么办？？？

rm -rf mysql/arch/* binlong 文件（二进制数据文件，有保留期限）
rm -rf mysql/data/* 数据文件
重新进行初始化就行了。

bin/mysqld
–defaults-file=/etc/my.cnf
–user=mysqladmin
–basedir=/usr/local/mysql/
–datadir=/usr/local/mysql/data/
–initialize
