一、准备阶段

通常情况下,MySQL在CentOS下主要使用glibc、rpm、yum等方式进行安装,使用mysql-5.7.21-el7-x86_64.tar.gz包进行安装的很少见,网上资料也较少。通过一上午的摸索,总结出如下安装方法。

下载安装包:

[root@GeekDevOps ~]# curl -C - -O https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.21-el7-x86_64.tar.gz
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  674M  100  674M    0     0  4311k      0  0:02:40  0:02:40 --:--:-- 4067k

创建安装账户:

[root@GeekDevOps ~]# useradd -s /bin/false -d /usr/local/mysql  mysql
[root@GeekDevOps ~]# id mysql
uid=1000(mysql) gid=1000(mysql) 组=1000(mysql)
二、安装过程
[root@GeekDevOps ~]# tar -xvzf mysql-5.7.21-el7-x86_64.tar.gz -C /usr/local/mysql/
[root@GeekDevOps mysql]# cd /usr/local/mysql/mysql-5.7.21-el7-x86_64/
[root@GeekDevOps mysql-5.7.21-el7-x86_64]# mv * ../
[root@GeekDevOps mysql-5.7.21-el7-x86_64]# cd ..
[root@GeekDevOps mysql]# rmdir mysql-5.7.21-el7-x86_64/
[root@GeekDevOps mysql]# mkdir data
[root@GeekDevOps mysql]# chown -R mysql.mysql ../mysql
[root@GeekDevOps mysql]# cd bin
[root@GeekDevOps bin]# ./mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --initialize
[root@GeekDevOps bin]# tail -100f ../data/error.log 
2018-03-14T06:32:34.966407Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2018-03-14T06:32:36.208273Z 0 [Warning] InnoDB: New log files created, LSN=45790
2018-03-14T06:32:36.367294Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2018-03-14T06:32:36.522777Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 7c405e3f-2751-11e8-8be8-000c29fb0102.
2018-03-14T06:32:36.525594Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
2018-03-14T06:32:36.526540Z 1 [Note] A temporary password is generated for root@localhost: 7Eu;dsRqkY.3
[root@GeekDevOps bin]# cp ../support-files/mysql.server /etc/init.d/mysqld
三、配置过程
[root@GeekDevOps ~]# vi /etc/my.cnf
[mysqld]
port = 3306
basedir = /usr/local/mysql
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
pid-file=/usr/local/mysql/data/mysql.pid
log-error=/usr/local/mysql/data/error.log
character_set_server=utf8
user=mysql
max_connections=1500
symbolic-links=0
!includedir /etc/my.cnf.d
四、启动服务并登陆
[root@GeekDevOps ~]# service mysqld start
Starting MySQL. SUCCESS! 
[root@GeekDevOps mysql]# ./bin/mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql> 

在此过程中要求输入密码,在第三步中我们可以看到安装完成后的密码:7Eu;dsRqkY.3,输入即可登陆成功。

五、修改密码
mysql> set password=password('GeekDevOps');
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> quit
Bye

下次登录即可使用新密码进行登录。安装过程至此结束,其他配置与我之前写的glibc版的别无二致,此处不再赘述,其他配置请在my.cnf按照自己的需求进行配置。

六、安装过程中出现的问题
  1. 在安装完成之后,查看日志我们看到:TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details)。这是一个常见问题,在配置文件/etc/my.cnf的mysqld块添加:explicit_defaults_for_timestamp=1,重启数据库服务。
  2. 在完成上一步操作的过程中,查看日志发现提示:--secure-file-priv is set to NULL. Operations related to importing and exporting data are disabled。意思是与导出、导入有关的操作都是被禁用的,我们需要导出、导入的话就需要设置,在配置文件/etc/my.cnf中mysqld下加入:secure_file_priv=/test(目录可以按需求更改),这一项也可以在安装初始化的时候加入:--secure-file-priv=/test。
七、总结

mysql-5.7.21-el7-x86_64.tar.gz该版本的MySQL安装教程在网上并不常见,我是通过tar.gz包内的文档(/usr/local/mysql/docs/INFO_BIN)受到启发才进行安装的,从文档中我们可以看到编译的详细信息。
