CentOS 6.9上安装MySQL 5.6.36 笔记

[日期:2017-07-18] 来源:Linux社区  作者:Linux [字体: ]

分享一篇在CentOS 6.9上安装MySQL 5.6.36 的心得笔记,供大家参考。

1、准备数据存放的文件系统

新建一个逻辑卷,并将其挂载至特定目录即可。这里不再给出过程。

这里假设其逻辑卷的挂载目录为/data,而后需要创建/data/mysqldata目录做为mysql数据的存放目录。

[root@001 /]# mkdir -p /data/mysqldata

2、新建用户以安全方式运行进程:

[root@001 ~]# groupadd -r mysql

[root@001 ~]# useradd -g mysql -r -s /sbin/nologin -M -d /data/mysqldata mysql

[root@001 ~]# chown -R mysql:mysql /data/mysqldata

3、安装并初始化mysql-5.6.23

首先下载linux64位二进制版本的MySQL5.6至本地,mysql-advanced-5.6.23-linux-glibc2.5-x86_64.tar.gz

[root@001 ~]# tar zxf mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz -C /usr/local/ #根据实际情况修改

[root@001 ~]# cd /usr/local/

[root@001 ~]# ln -sv mysql-5.6.36-linux-glibc2.5-x86_64/ mysql #根据实际情况修改

[root@001 ~]# cd mysql

[root@001 ~]# chown -R mysql:mysql .

4.为mysql提供主配置文件: #默认初始化后会在/etc下有my.cnf,如有内容删除覆盖即可

以下为配置文件:

[root@001 mysql]# vim /etc/my.cnf

-----------------------------------------------------------------------------------------------------------

[client]

#user=mysql #根据实际情况设置用户名

#password=123456

[mysqld]

innodb_log_group_home_dir = /data/mysqldata #根据实际情况修改

innodb_undo_directory = /data/mysqldata #根据实际情况修改

innodb_undo_logs = 128

innodb_undo_tablespaces = 3

-----------------------------------------------------------------------------------------------------------------------------------------------------------

[root@001 mysql]# scripts/mysql_install_db --user=mysql --datadir=/data/mysqldata/

[root@001 mysql]# chown -R root .

5、为mysql提供sysv服务脚本:

[root@master ~]# cd /usr/local/mysql

[root@master ~]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld

[root@master ~]# ldconfig

6、修改PATH环境变量,让系统可以直接使用mysql的相关命令。

[root@master ~]# echo "PATH=$PATH:/usr/local/mysql/bin" > /etc/profile.d/mysql.sh

[root@master ~]# source /etc/profile.d/mysql.sh

 

7、最后启动服务添加开机启动

[root@master ~]# service mysqld start

[root@001 mysql]# chkconfig mysqld on

[root@001 bin]# mysql -u root -p #密码空

8、修改密码

mysql> set password = password('123456')
