Linux下安装MySQL数据库(压缩包方式安装)

2024-09-09 03:10:23   216人阅读

1、这里我将Mysql安装在/usr/local/mysql目录里面，也可以安装在其他地方;

mkdir /usr/local/mysql

2、下载MySQL压缩包

wget http://dev.MySQL.com/get/Downloads/MySQL-5.7/mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz

3、解压并复制

tar -xvf mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz
mv mysql-5.7.11-Linux-glibc2.5-x86_64/* /usr/local/mysql/

4、创建data目录

mkdir /usr/local/mysql/data

5、创建mysql用户组及其用户

groupadd mysql
useradd -r -g mysql mysql

6、初始化数据

[root@localhost mysql] ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/
2016-01-20 02:47:35 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2016-01-20 02:47:45 [WARNING] The bootstrap log isn‘t empty:
2016-01-20 02:47:45 [WARNING] 2016-01-19T18:47:36.732678Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead
2016-01-19T18:47:36.750527Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)
2016-01-19T18:47:36.750560Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)

7、复制配置文件到 /etc/my.cnf

cp -a ./support-files/my-default.cnf /etc/my.cnf (选择y)

8、MySQL的服务脚本放到系统服务中

cp -a ./support-files/mysql.server /etc/init.d/mysqld
修改my.cnf文件
# These are commonly set, remove the # and set as required.
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
# server_id = .....
socket = /tmp/mysql.sock
character-set-server = utf8
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

9、创建In

ln -s /usr/local/mysql/  /usr/bin/

10、启动服务

service mysqld start

11、初始化密码

mysql5.7会生成一个初始化密码，在root中.mysql_secret文件中。

[root@localhost ~]# cat /root/.mysql_secret
# Password set for user ‘root@localhost‘ at 2017-03-16 00:52:34 
ws;fmT7yh0CM

12、登录并修改密码

[root@localhost ~]# mysql -u root -p

alter user root@localhost identified by ‘tiger‘;

flush privileges;

13、退出重新登录，完成

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+
4 rows in set (0.11 sec)

OK
