linux 环境RPM 安装MYSQL5.6

系统环境 CentOS7.2

1.关闭selinux 服务【SELinux是一种基于域-类型 模型（domain-type）的强制访问控制（MAC）安全系统】

[root@OperationsAnalysis ~]# vim /etc/selinux/config 
···
SELINUX=disabled
···

2.关闭防火墙服务，并且禁用开机启动

[root@OperationsAnalysis ~]# systemctl stop firewalld.service
[root@OperationsAnalysis ~]# systemctl disable firewalld.service

3.关闭NetworkManager服务，并且禁用开机启动【(NetworManager)是检测网络、自动连接网络的程序】

[root@OperationsAnalysis ~]# systemctl stop NetworkManager.service
[root@OperationsAnalysis ~]# systemctl disable NetworkManager.service

4.检查系统是否安装有mysql的安装包，如果有使用rpm -e 移除

[root@OperationsAnalysis ~]# rpm -qa| grep mysql

5.下载mysql5.6的安装包，并上传到服务器上

[root@OperationsAnalysis mysql]# ll
total 236180
-rw-r--r-- 1 root root 20278972 Sep 22 15:41 MySQL-client-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root  3529244 Sep 22 15:40 MySQL-devel-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root 92246408 Sep 22 15:44 MySQL-embedded-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root 61732192 Sep 22 15:42 MySQL-server-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root  2101912 Sep 22 15:42 MySQL-shared-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root  2299648 Sep 22 15:40 MySQL-shared-compat-5.6.31-1.el7.x86_64.rpm
-rw-r--r-- 1 root root 59644132 Sep 22 15:40 MySQL-test-5.6.31-1.el7.x86_64.rpm

6.安装mysql 的安装包

[root@OperationsAnalysis mysql]# rpm -ivh MySQL-server-5.6.31-1.el7.x86_64.rpm 
[root@OperationsAnalysis mysql]# rpm -ivh MySQL-devel-5.6.31-1.el7.x86_64.rpm 
[root@OperationsAnalysis mysql]# rpm -ivh MySQL-client-5.6.31-1.el7.x86_64.rpm

7.修改my.cnf配置文件位置

[root@OperationsAnalysis ~]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

8.修改字符集和数据存储路径 配置/etc/my.cnf文件,设置如下键值来启用一起有用的选项和 UTF-8 字符集.

[root@OperationsAnalysis ~]# cat /etc/my.cnf
[mysqld]
···
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

9.初始化MySQL及设置密码

[root@OperationsAnalysis ~]# /usr/bin/mysql_install_db
[root@OperationsAnalysis ~]# service mysql start
[root@OperationsAnalysis ~]# cat /root/.mysql_secret
# The random password set for the root user at Mon Dec 26 20:43:34 2016 (local time): 1dwIOrYEiaPsCyTM
[root@OperationsAnalysis ~]# mysql -uroot -p1dwIOrYEiaPsCyTM
mysql> SET PASSWORD = PASSWORD(‘abcd1234‘);
Query OK, 0 rows affected (0.00 sec)

10.设置mysql开机启动

[root@OperationsAnalysis ~]# systemctl restart mysqld.service
[root@OperationsAnalysis ~]# systemctl enable mysqld.service

11.设置mysql允许远程登陆

12.安装mysql出现安装包不兼容问题

[root@OperationsAnalysis mysql]# rpm -ivh MySQL-server-5.6.31-1.el7.x86_64.rpm
warning: MySQL-server-5.6.31-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

解决方法，删除不兼容安装包

[root@OperationsAnalysis mysql]# rpm -qa |grep mariadb*
mariadb-libs-5.5.41-2.el7_0.x86_64
[root@OperationsAnalysis mysql]# rpm -e mariadb-libs-5.5.41-2.el7_0.x86_64 （有依赖包，建议使用yum移除）
error: Failed dependencies:
