mysql5.7.13Generic安裝步驟

1.下載5.7.13Generic64位版本軟件

具體鏈接地址：http://dev.mysql.com/downloads/mysql/。我在寫這篇博客的時候剛好5.7.14出來了。

2.下載Generic版本

[root@localhost Csong]# ll
total 624872
drwxr-xr-x. 9 7161 wheel      4096 May 25 15:04 mysql-5.7.13-linux-glibc2.5-x86_64
-rw-r--r--. 1 root root  639864682 Aug  3 10:42 mysql-5.7.13-linux-glibc2.5-x86_64.tar.gz

3.用root登入Linux，並創建mysql用戶組和mysql用戶

[root@localhost local]# id mysql
uid=27(mysql) gid=27(mysql) groups=27(mysql)

3.解壓並拷貝至/usr/local/下，重命名爲mysql文件夾，修改mysql文件夾的權限爲mysql

[root@localhost local]# ll
total 4
drwxr-xr-x.  2 root  root     6 Aug 12  2015 bin
drwxr-xr-x.  2 root  root     6 Aug 12  2015 etc
drwxr-xr-x.  2 root  root     6 Aug 12  2015 games
drwxr-xr-x.  2 root  root     6 Aug 12  2015 include
drwxr-xr-x.  2 root  root     6 Aug 12  2015 lib
drwxr-xr-x.  2 root  root     6 Aug 12  2015 lib64
drwxr-xr-x.  2 root  root     6 Aug 12  2015 libexec
drwxr-xr-x. 11 mysql mysql 4096 Aug  4 23:05 mysql
drwxr-xr-x.  2 root  root     6 Aug 12  2015 sbin
drwxr-xr-x.  5 root  root    46 Aug  2 16:18 share
drwxr-xr-x.  2 root  root     6 Aug 12  2015 src
[root@localhost local]# cd mysql/
[root@localhost mysql]# ll
total 48
drwxr-xr-x.  2 mysql mysql  4096 Aug  7 06:33 bin

drwxr-xr-x.  3 mysql mysql    23 Aug  3 10:51 data
drwxr-xr-x.  2 mysql mysql    52 Aug  3 10:47 docs
drwxr-xr-x.  3 mysql mysql  4096 Aug  3 10:47 include
drwxr-xr-x.  5 mysql mysql  4096 Aug  3 10:46 lib
drwxr-xr-x.  4 mysql mysql    28 Aug  3 10:47 man
-rw-r--r--.  1 mysql mysql  2478 Aug  3 10:45 README
drwxr-xr-x. 28 mysql mysql  4096 Aug  3 10:46 share
drwxr-xr-x.  2 mysql mysql  4096 Aug  3 10:46 support-files

4.創建defaults-file文件

這個文件在初始化的時候可以用到，啓動的時候也可以用到，你可以改成你想要的任何名字，我這裏規定了我的mysql的端口號是3307，並且我單獨在根目錄下創建了一個給mysql使用的數據目錄，並且創建了我的defaults-file，名字爲mysql_3307.cnf。

[root@localhost mysql_3307]# pwd
/data/mysql_3307
[root@localhost mysql_3307]# ll
total 12
drwxr-x---. 5 mysql mysql 4096 Aug  7 07:35 data
drwxr-xr-x. 2 mysql mysql 4096 Aug  7 07:10 logs
-rw-r--r--. 1 mysql mysql  376 Aug  5 14:02 mysql_3307.cnf
drwxr-xr-x. 2 mysql mysql    6 Aug  7 07:10 tmp

[root@localhost mysql_3307]# cat mysql_3307.cnf 
[mysqld]
basedir = /usr/local/mysql/
datadir = /data/mysql_3307/data/
port = 3307
server-id = 2
socket = /tmp/mysql_3307.sock
binlog_format = mixed
gtid-mode = off
#gtid-mode=on  ##GTID type
#enforce-gtid-consistency=on  ##GTID type
#log_slave_updates  ##GTID type
log-bin = /data/mysql_3307/logs/mybinlog
tmpdir = /data/mysql_3307/tmp
log-error = error.log
log-output = file

5.初始化mysqld

[root@localhost mysql_3307]# /usr/local/mysql/bin/mysqld --defaults-file=/data/mysql_3307/mysql_3307.cnf --initialize --user=mysql
[root@localhost mysql_3307]# /usr/local/mysql/bin/mysql_ssl_rsa_setup --basedir=/usr/local/mysql/ --datadir=/data/mysql_3307/data

ca.pem           ib_buffer_pool  mysql               server-cert.pem
client-cert.pem  ibdata1         performance_schema  server-key.pem

6.啓動mysql實例

[root@localhost mysql_3307]# /usr/local/mysql/bin/mysqld --defaults-file=/data/mysql_3307/mysql_3307.cnf --user=mysql &
[1] 14452

7.連接mysql

[root@localhost mysql_3307]# /usr/local/mysql/bin/mysql -S /tmp/mysql_3307.sock -uroot -p
Enter password:         --注意，這裏的密碼，默認mysql會生成一個hash後的初始密碼，密碼在error.log中，這個error.log的位置在defaults-file中有定義。

[root@localhost mysql_3307]# /usr/local/mysql/bin/mysql -S /tmp/mysql_3307.sock -uroot -p
Enter password:

mysql> 

至此，mysql5.7.13已經安裝完畢了。但是，現在mysql中的root用戶，遠程是登入不了的，因爲權限沒開放。

可以在mysql命令窗口中輸入grant all on *.* to 'root'@'%' identified by '123456';

這樣就可以了。
