本站教程收集整理的这篇文章主要介绍了centos6.7 64位环境下部署MySQL-5.7.13，本站教程本站觉得挺不错的，现在分享给大家，也给大家做个参考。
系统环境:
@H_403_9@[root@localhost ~]# cat /etc/redhat-release
@H_403_9@CentOS release 6.7 (Final)
@H_403_9@[root@localhost tools]# uname -a
@H_403_9@Linux localhost 2.6.32-573.22.1.el6.x86_64 #1 SMP Wed Mar 23 03:35:39 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
@H_403_9@[root@localhost tools]#
软件准备:
@H_403_9@[root@localhost tools]# pwd
@H_403_9@/opt/tools
@H_403_9@[root@localhost tools]# ll
@H_403_9@@R_349_10586@l 674208
@H_403_9@-rw-r–r– 1 root root 639864682 Jul 22 17:47 MysqL-5.7.13-linux-glibc2.5-x86_64.tar.gz
@H_403_9@-rw-r–r– 1 root root 50516207 May 25 12:01 MysqL-5.7.13.tar.gz
解压安装:
@H_403_9@[root@localhost tools]# tar xf MysqL-5.7.13-linux-glibc2.5-x86_64.tar.gz
@H_403_9@@R_349_10586@l 674212
@H_403_9@drwxr-xr-x 9 7161 wheel 4096 May 25 15:04 MysqL-5.7.13-linux-glibc2.5-x86_64
@H_403_9@-rw-r–r– 1 root root 50516207 May 25 12:01 MysqL-5.7.13.tar.gz
@H_403_9@[root@localhost tools]#
@H_403_9@[root@localhost tools]# mv MysqL-5.7.13-linux-glibc2.5-x86_64 /usr/local/MysqL
初始化操作(生成初始密码):
@H_403_9@[root@localhost MysqL]# ./bin/MysqLd –initialize –user=MysqL –basedir=/usr/local/MysqL –datadir=/data/MysqL/data
@H_403_9@2016-07-22T09:58:15.001776Z 0 [Warning] InnoDB: New log files created,LSN=45790

@H_403_9@2016-07-22T09:58:15.074370Z 0 [Warning] Gtid table is not ready to be used. Table ‘Mysql.gtid_executed’ cAnnot be opened.
@H_403_9@2016-07-22T09:58:15.075736Z 1 [Note] A temporary password is generated for root@localhost: k_1ljzVh3<-,
@H_403_9@[root@localhost MysqL]#
PS:MysqL5.7新特性：由上面可以看出， MysqL_inst@R_607_10636@db 已经不再推荐使用了，建议改成 MysqLd –initialize 完成实例初始化。
@H_403_9@
加入MysqL为系统服务:
@H_403_9@[root@localhost MysqL]# cp support-files/Mysql.server /etc/init.d/MysqLd
@H_403_9@[root@localhost MysqL]# chkconfig MysqLd on
@H_403_9@[root@localhost MysqL]# chkconfig –list|grep MysqLd
@H_403_9@mysqLd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
@H_403_9@[root@localhost MysqL]#chmod 755 /etc/init.d/MysqLd
@H_462_39@mysqL服务启动、重启、停止
@H_403_9@[root@localhost MysqL]# serivce MysqLd start
@H_403_9@[root@localhost MysqL]# serivce MysqLd stop
@H_403_9@[root@localhost MysqL]# serivce MysqLd restart
@H_403_9@[root@localhost MysqL]#
设置环境变量:
@H_403_9@[root@localhost MysqL]# vim /etc/profile
@H_403_9@export PATH=/usr/local/MysqL/bin:$PATH
@H_403_9@[root@localhost MysqL]#
检查MysqL是否能开启
[root@localhost MysqL]# cd /usr/local/MysqL
[root@localhost MysqL]# cd support-files/
[root@localhost support-files]# ./Mysql.server start
StarTing Mysql.. succesS!
@H_403_9@若改用了， 则在启动服务时会出现如下错误：
@H_403_9@# ./support-files/Mysql.server start
@H_403_9@./support-files/Mysql.server: line 276: cd: /usr/local/MysqL: No such file or directory
@H_403_9@StarTing MysqL ERROR! Couldn’t find MysqL server (/usr/local/MysqL/bin/MysqLd_safE)
@H_403_9@这时候我们需要修改/support-files/Mysql.server文件的basedir和datadir目录路径为我们正确的MysqL的basedir和datadir路径， 如下：
@H_403_9@# vim support-files/Mysql.server
@H_403_9@————————–
@H_403_9@…
@H_403_9@basedir=/usr/local/MysqL
@H_403_9@datadir=/data/MysqL/data
@H_403_9@# ./support-files/Mysql.server start
@H_403_9@StarTing Mysql.. succesS!
@H_403_9@创建配置文件
将默认生成的my.cnf备份
# mv /etc/my.cnf /etc/my.cnf.bak
[root@localhost support-files]# cp my-default.cnf /etc/my.cnf
初始化MysqL用户root的密码
先将MysqL服务停止
# service MysqLd stop
进入MysqL安装目录， 执行：
# cd /usr/local/MysqL
# ./bin/MysqLd_safe –skip-grant-tables –skip-networking&香港vps
[1] 6225
[root@localhost MysqL]# 151110 02:46:08 MysqLd_safe Logging to ‘/data/MysqL/data/localhost.localdomain.err’.
151110 02:46:08 MysqLd_safe StarTing MysqLd daemon with databases from /data/MysqL/data
另外打开一个终端(p.s. 如果是ssh连接登录的,另外创建一个ssh连接即可）， 执行操作如下：
# MysqL -u root MysqL

@H_29_1@mysqL>
到此， 设置完MysqL用户root的密码且确保MysqL编码集是utf8,注意上面， 新版本的Mysql.user表里的密码字段是authentication_String
@H_710_2@mysqL远程授权
格式如下：
@H_29_1@mysqL> grant all [privileges] on db_name.table_name to ‘username’@’host’ identified by ‘password’;
示例如下：
@H_29_1@mysqL> grant all privileges on *.* to ‘root’@’%’ identified by ‘123456’;
Query OK,0 rows affected,1 warning (0.04 seC)
@H_29_1@mysqL> FLUSH PRIVILEGES;
Query OK,0 rows affected (0.00 seC)
@H_29_1@mysqL>
或用
@H_29_1@mysqL> grant all on *.* to ‘root’@’%’ identified by ‘123456’;
到此， 完成了MysqL的安装 及配置！！！
