本文实例讲述了CentOS7安装mysql5.7解压缩版的方法。分享给大家供大家参考，具体如下：

1.下载安装包

http://dev.mysql.com/downloads/mysql/#downloads
推荐下载通用安装方法的TAR包

2.检查库文件是否存在，如有删除。

[root@localhost Desktop]$ rpm -qa | grep mysql
mysql-libs-5.1.52-1.el6_0.1.x86_64
[root@localhost ~]$ rpm -e mysql-libs-5.1.52.x86_64 --nodeps
[root@localhost ~]$

3.检查mysql组和用户是否存在，如无创建。

[root@localhost ~]$ cat /etc/group | grep mysql
mysql:x:490:
[root@localhost ~]$ cat /etc/passwd | grep mysql
mysql:x:496:490::/home/mysql:/bin/bash
以上为默认存在的情况，如无，执行添加命令：
[root@localhost ~]$groupadd mysql
[root@localhost ~]$useradd -r -g mysql mysql
//useradd -r参数表示mysql用户是系统用户，不可用于登录系统。

4.解压TAR包，更改所属的组和用户

[root@localhost ~]$ cd /usr/local/
[root@localhost local]$ tar xvf mysql-5.7.12-linux-glibc2.5-x86_64.tar
[root@localhost local]$ ls -l
total 1306432
-rwxr--r--. 1 root root 668866560 Jun 1 15:07 mysql-5.7.12-linux-glibc2.5-x86_64.tar
-rw-r--r--. 1 7161 wheel 638960236 Mar 28 12:54 mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz
-rw-r--r--. 1 7161 wheel 29903372 Mar 28 12:48 mysql-test-5.7.12-linux-glibc2.5-x86_64.tar.gz
[root@localhost local]$ tar xvfz mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz
[root@localhost local]$ mv mysql-5.7.12-linux-glibc2.5-x86_64 mysql
[root@localhost local]$ ls -l
total 1306436
drwxr-xr-x. 2 root root    4096 Dec 4 2009 bin

drwxr-xr-x. 9 7161 wheel   4096 Mar 28 12:51 mysql
-rwxr--r--. 1 root root 668866560 Jun 1 15:07 mysql-5.7.12-linux-glibc2.5-x86_64.tar
-rw-r--r--. 1 7161 wheel 638960236 Mar 28 12:54 mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz
-rw-r--r--. 1 7161 wheel 29903372 Mar 28 12:48 mysql-test-5.7.12-linux-glibc2.5-x86_64.tar.gz
drwxr-xr-x. 2 root root    4096 Dec 4 2009 sbin
drwxr-xr-x. 6 root root    4096 Dec 2 14:36 share
drwxr-xr-x. 2 root root    4096 Dec 4 2009 src
[root@localhost local]$ chown -R mysql mysql/
[root@localhost local]$ chgrp -R mysql mysql/
[root@localhost local]$ cd mysql/

5.安装和初始化数据库

[root@localhost mysql]$ bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/
2016-06-01 15:23:25 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2016-06-01 15:23:30 [WARNING] The bootstrap log isn't empty:
2016-06-01 15:23:30 [WARNING] 2016-06-01T22:23:25.491840Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead
2016-06-01T22:23:25.492256Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)
2016-06-01T22:23:25.492260Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)

如果改变默认安装路径，则需要  1）/etc/my.cnf、/etc/init.d/mysqld中修改  basedir='/apps/mysql'  datadir='/apps/mysql/data'  2）创建ln  mkdir -p /usr/local/mysql/bin  ln -s /apps/mysql/bin/mysqld /usr/local/mysql/bin/mysqld

[root@localhost mysql]$
[root@localhost mysql]$ cp -a ./support-files/my-default.cnf /etc/my.cnf
[root@localhost mysql]$ cp -a ./support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]$ cd bin/
[root@localhost bin]# ./mysqld_safe --user=mysql &
[1] 2932
[root@localhost bin]# 2016-06-01T22:27:09.708557Z mysqld_safe Logging to '/usr/local/mysql/data/localhost.localdomain.err'.
2016-06-01T22:27:09.854913Z mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
[root@localhost bin]# /etc/init.d/mysqld restart
Shutting down MySQL..2016-06-01T22:27:50.498694Z mysqld_safe mysqld from pid file /usr/local/mysql/data/localhost.localdomain.pid ended
 SUCCESS!
Starting MySQL. SUCCESS!
[1]+ Done          ./mysqld_safe --user=mysql
[root@localhost bin]$
//设置开机启动
[root@localhost bin]$ chkconfig --level 35 mysqld on
[root@localhost bin]$

6.初始化密码

mysql5.7会生成一个初始化密码，而在之前的版本首次登陆不需要登录。

[root@localhost bin]$ cat /root/.mysql_secret
# Password set for user 'root@localhost' at 2016-06-01 15:23:25
,xxxxxR5H9
[root@localhost bin]$./mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.7.12

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> SET PASSWORD = PASSWORD('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

7.添加远程访问权限

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> update user set host = '%' where user = 'root';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select host, user from user;
+-----------+-----------+
| host   | user   |
+-----------+-----------+
| %     | root   |
| localhost | mysql.sys |
+-----------+-----------+
//一定要重启才会生效。
/etc/init.d/mysqld restart

遇到的问题：

找不到mysql.sock，mysql.sock丢失问题解决方法

连接Mysql时，机器上找不到mysql.sock文件你可以简单地通过重启服务器重新创建得到它。因为服务器在启动时重新创建它。

[root@localhost mysql-5.7.13]# ./bin/mysql_install_db --user=mysql
2016-06-26 02:47:09 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2016-06-26 02:47:09 [ERROR]  The data directory needs to be specified.

解决：需要新建data目录，指定安装目录(在非默认目录时需要指定，默认路径：/usr/local/mysql，同时需要指定./support-files/mysql.server中的basedir和datadir为相应路径)。

[root@localhost mysql-5.7.13]# ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql-5.7.13/ --datadir=/usr/local/mysql-5.7.13/data/
2016-06-26 02:48:47 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2016-06-26 02:49:19 [WARNING] The bootstrap log isn't empty:
2016-06-26 02:49:19 [WARNING] 2016-06-26T09:48:50.798592Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead
2016-06-26T09:48:50.898732Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)
2016-06-26T09:48:50.898778Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)

以上报错均因未在mysql.server中指定自定义的路径。

若是还提示已经有data文件了 删除了它，新建即可

希望本文所述对大家CentOS服务器维护有所帮助。
