Linux Centos7安裝MySQL5.5(二進制方式安裝)

Linux Centos7安裝MySQL5.5(二進制方式安裝)

1、在/app目錄下下載mysql-5.5.54-linux2.6-x86_64.tar.gz`

[root@test /]# cd /app
[root@test app]# wget http://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.54-linux2.6-x86_64.tar.gz

2、解壓mysql-5.5.54-linux2.6-x86_64.tar.gz

[root@test app]# ta zvxf mysql-5.5.54-linux2.6-x86_64.tar.gzmysql

3、將解壓後的mysql-5.5.54-linux2.6-x86_64更名爲mysql

[root@test app]# mv mysql-5.5.54-linux2.6-x86_64 mysqllinux

4、添加/etc/my.cnf文件

[root@test app]# cd /app/mysql/support-files/
[root@test support-files]# cp -f my-small.cnf /etc/my.cnf

5、建立mysql目錄下的data目錄

[root@test support-files]# mkdir -p /app/mysql/data/

6、將mysql的所屬用戶改成mysql

[root@test support-files]# chown -R mysql.mysql /app/mysql/

7、增長/etc/init.d/mysqld,併爲之賦予執行權限,而後初始化MySQL

[root@test support-files]# cp -f mysql.server /etc/init.d/mysqld
[root@test support-files]# chmod +x /etc/init.d/mysqld

【初始化MySQL】sql

[root@test support-files]# /app/mysql/scripts/mysql_install_db --basedir=/app/mysql --datadir=/app/mysql/data --user=mysql

8、將 /application/mysql/bin/mysqld_safe和/etc/init.d/mysqld中的/usr/local/mysql改成/app/mysq

[root@test support-files]# sed -i 's#/usr/local/mysql#/app/mysql#g' /app/mysql/bin/mysqld_safe /etc/init.d/mysqld

9、啓動mysql

[root@test support-files]# /etc/init.d/mysqld start
Starting MySQL.Logging to '/app/mysql/data/test.err'.
.. SUCCESS!

10、檢查mysql是否啓動

[root@test support-files]# netstat -lntup | grep mysql
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      5478/mysqld

11、設置環境變量

[root@test support-files]# echo 'export PATH=/app/mysql/bin:$PATH' >>/etc/profile
[root@test support-files]# source /etc/profile

12、進入mysql

[root@test support-files]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1

mysql>

十3、修改root密碼

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');

十4、退出MySQL,使用用戶名和密碼再次登陸MySQL

mysql> Ctrl-C -- exit!
Aborted
[root@test support-files]# mysql -uroot -p
Enter password:

十5、建立數據庫和表(指定utf-8編碼格式)

mysql> create database userInfo DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
Query OK, 1 row affected (0.00 sec)

mysql> use userInfo;
Database changed

mysql> create table test (
    -> name varchar(10) not null,
    -> address varchar(100) default null)
    -> ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
Query OK, 0 rows affected (0.06 sec)

十6、導入sql文件(若須要執行此步驟)

mysql> source /app/cloud_note.sql
mysql> show databases;
