1风宁、下載軟件
使用本地已下好的包 用rz上傳至linux
安裝上傳包：yum -y install lrzsz
rz 選擇mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz上傳
2、查看是否安裝
ps -ef|grep mysqld
3跨琳、查看是否有rpm包
rpm -qa |grep -i mysql
4、解壓并移動到mysql目錄
tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql
5被碗、創(chuàng)建用戶和組
新建dba組：groupadd -g 101 dba
創(chuàng)建用戶并添加dba組：useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
ps：生產(chǎn)環(huán)境中一般不會給root權限
先申請sudo權限窄锅，再創(chuàng)建一個mysql服務的管理用戶
創(chuàng)建mysqladmin作用：1、一個用戶只對一個組件 2蔑舞、dba組
6、修改密碼
passwd mysqladmin
7嘹屯、拷貝配置文件到mysqladmin用戶的家目錄
cp /etc/skel/.* /usr/local/mysql
8攻询、配置/etc/my.cnf：直接覆蓋
vi /etc/my.cn 先dg 在黏貼

修改innodb_buffer_pool_size = 2048M為1024M
9、修改配置文件及mysql目錄的權限及所有人/組
修改配置文件：chown mysqladmin:dba /etc/my.cnf chmod 640 /etc/my.cnf
修改目錄：chown -R mysqladmin:dba /usr/local/mysql chmod -R 755 /usr/local/mysql
10州弟、切換到mysqladmin用戶
su - mysqldamin
11钧栖、查看當前路徑 新建歸檔目錄
pwd /usr/local/mysql
mkdir arch
12低零、安裝
scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
13、配置mysql服務拯杠，并改為開機啟動
1.root用戶先切換到mysql根目錄 cd /usr/local/mysql
2.root用戶下將服務文件拷貝到init.id下掏婶，并重命名為mysql cp support-files/mysql.server /etc/rc.d/init.d/mysql
3.賦予可執(zhí)行權限： chmod +x /etc/rc.d/init.d/mysql
4.添加服務 ： chkconfig --add mysql
5.設置開機啟動： chkconfig --level 345 mysql on
14、啟動mysql并查看流程和監(jiān)聽
1.切換用戶：su - mysqladmin
2.rm -rf my.cnf
bin/mysqld_safe &
3.查看進程及端口號
ps -ef|grep mysqld
netstat -tulnp | grep mysql
15潭陪、查看mysql服務
service mysql status
16雄妥、登錄mysql
[mysqladmin@hadoop001 ~]$ mysql
mysql>
17、查看數(shù)據(jù)庫
mysql>show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
+--------------------+
4 rows in set (0.02 sec)
18依溯、更新密碼及清除用戶
1.進入數(shù)據(jù)庫mysql：
use mysql
Database changed
2.查看用戶表：select host,user,password from user;
+-----------+------+----------+
| host | user | password |
+-----------+------+----------+
| localhost | root | |
| hadoop001 | root | |
| 127.0.0.1 | root | |
| ::1 | root | |
| localhost | | |
| hadoop001 | | |
+-----------+------+----------+
6 rows in set (0.00 sec)
3.更新root用戶密碼為‘123456’：update user set password=password('123456') where user='root';
Query OK, 4 rows affected (0.02 sec)
Rows matched: 4 Changed: 4 Warnings: 0
4.再次查看用戶表：select host,user,password from user;
+-----------+------+-------------------------------------------+
| host | user | password |
+-----------+------+-------------------------------------------+
| localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| hadoop001 | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| 127.0.0.1 | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| ::1 | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| localhost | | |
| hadoop001 | | |
+-----------+------+-------------------------------------------+
6 rows in set (0.00 sec)
密碼已更新
19老厌、MySQL重新部署
rm -rf arch/* data/* 刪除歸檔文件及數(shù)據(jù)文件
scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 重新部署
20、修改% 任意機器可訪問
update mysql.user set Host='%' where Host='hadoop000';
flush privileges;
安裝dbeaver 工具鏈接 即可連接到數(shù)據(jù)庫
21黎炉、mysql命令參數(shù)
mysql -uroot -p123456
mysql -u root -p123456
mysql -u root -p 123456 不可以（空格會代表一位密碼）
mysql -u root -p123456 -h192.168.137.251
mysql -u root -p123456 -hlocalhost mysql
22枝秤、創(chuàng)建數(shù)據(jù)庫及用戶
create database ruozedb; 創(chuàng)建數(shù)據(jù)庫
grant all privileges on ruozedb.* to hutu@'192.167.137.2' identified by '123456'; 新建賬號密碼并授權
flush privileges; dbeaver登錄
23、查看進程
show processlist慷嗜；
24淀弹、殺死進程
kill id（沒有-9）
