Linux6.5编译安装mysql5.7.19

一、准备工作

1.下载mysql安装包并传到服务器上进行解压后得到如下一系列安装包：

[root@HZHG-P mysql]# ls
data                                            mysql-community-libs-5.7.19-1.el6.x86_64.rpm
mysql-community-client-5.7.19-1.el6.x86_64.rpm  mysql-community-libs-compat-5.7.19-1.el6.x86_64.rpm
mysql-community-common-5.7.19-1.el6.x86_64.rpm  mysql-community-server-5.7.19-1.el6.x86_64.rpm
mysql-community-devel-5.7.19-1.el6.x86_64.rpm

//由于是采用编译式安装，所以是rpm包的形式

2.安装前检查下是否有操作系统自带的mysql版本，如果有的话现卸载：

[root@HZHG-P mysql]# rpm -qa|grep mysql
mysql-libs-5.1.71-1.el6.x86_64

[root@HZHG-P mysql]# rpm -ev mysql-libs-5.1.71-1.el6.x86_64 --nodeps    //--nodeps表示强制删除，忽略依赖
[root@HZHG-P mysql]# rpm -qa|grep mysql  //再次检查，无任何输出，表示已卸载
[root@HZHG-P mysql]#

二、安装：

1.安装rpm包

[root@HZHG-P mysql]# rpm -ivh mysql-community-libs-5.7.19-1.el6.x86_64.rpm mysql-community-client-5.7.19-1.el6.x86_64.rpm mysql-community-libs-compat-5.7.19-1.el6.x86_64.rpm mysql-community-common-5.7.19-1.el6.x86_64.rpm mysql-community-server-5.7.19-1.el6.x86_64.rpm mysql-community-devel-5.7.19-1.el6.x86_64.rpm

warning: mysql-community-libs-5.7.19-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:

//报错

[root@HZHG-P mysql]# yum install  numactl //解决方法

[root@HZHG-P mysql]# rpm -ivh mysql-community-libs-5.7.19-1.el6.x86_64.rpm mysql-community-client-5.7.19-1.el6.x86_64.rpm mysql-community-libs-compat-5.7.19-1.el6.x86_64.rpm mysql-community-common-5.7.19-1.el6.x86_64.rpm mysql-community-server-5.7.19-1.el6.x86_64.rpm mysql-community-devel-5.7.19-1.el6.x86_64.rpm
warning: mysql-community-libs-5.7.19-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

//出现以上情况表示安装成功 由于这几个包有顺序依赖，所以建议全部一起安装，系统会自动识别

2.修改配置文件：

[root@HZHG-P mysql]# vi /etc/my.cnf   //默认mysql配置文件路径

datadir=/backup/mysql/data    //mysql数据存储目录
socket=/var/lib/mysql/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
log-bin=/backup/mysql/data/mysql-bin      //开启binlog日志，为搭建主从做准备
server_id=123458                        //设定server_id，为搭建主从做准备

3.启动mysql服务，初始化数据库和密码：

[root@HZHG-P mysql]# service mysqld start    //启动mysql服务
Initializing MySQL database:                               [  OK  ]
Starting mysqld:                                           [  OK  ]

[root@HZHG-P mysql]# mysqld --defaults-file=/etc/my.cnf --initialize-insecure --user=mysql
2019-04-17T07:08:18.494959Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use

2019-04-17T07:08:18.496950Z 0 [ERROR] --initialize specified but the data directory has files in it. Aborting.
2019-04-17T07:08:18.496973Z 0 [ERROR] Aborting
/* 由于启动mysql服务时已经初始化了，导致配置文件中datadir路径下已经存在数据，该问题可以通过删除datadir路径下的所有东西来解决，初始化成功后可在mysql日志中
查看初始化的临时密码*/   

[root@HZHG-P data]# rm -rf *  /*执行该操作中在第一步启动mysql服务时提示了已初始化数据库，安装的时候没查看日志是否已初始化，
                                下次安装时可以先检查一下，再进行后续的删除文件，初始化步骤*/
[root@HZHG-P data]# mysqld --defaults-file=/etc/my.cnf --initialize-insecure --user=mysql   //初始化

[root@HZHG-P data]# ls  
auto.cnf ibdata1 ib_logfile1 mysql-bin.000001 performance_schema
ib_buffer_pool ib_logfile0 mysql mysql-bin.index sys

//初始化成功后可在mysql日志中查看临时密码

[root@HZHG-P data]# vi /var/log/mysqld.log

2019-04-17T07:07:38.928820Z 1 [Note] A temporary password is generated for root@localhost: 9sqss4;Klp1y  
//该密码是初始化时随机生成的，只用于首次登陆

[root@HZHG-P data]# mysql -uroot -p9sqss4;Klp1y      //登陆mysql

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

mysql> set password = password('Password');  //设定密码

mysql> grant all privileges on *.* to root@"%" identified by "Password" with grant option; //授权可远程登陆mysql

mysql> flush privileges;

                                                                                   导致user表被损坏，可用如下方式修复表*/

mysql> repair table user; //修复表

+------------+--------+----------+------------------------------------+
| Table      | Op     | Msg_type | Msg_text                           |
+------------+--------+----------+------------------------------------+
| mysql.user | repair | warning  | Number of rows changed from 3 to 4 |
| mysql.user | repair | status   | OK                                 |
+------------+--------+----------+------------------------------------+

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

至此，rpm方式安装mysql成功。
