MySQL 5.7.21基于OEL6.9 平台的通用二进制安装方法

下文主要给大家带来MySQL 5.7.21基于OEL6.9 平台的通用二进制安装方法，希望MysqL 5.7.21基于OEL6.9 平台的通用二进制安装方法能够带给大家实际用处，这也是我编辑这篇文章的主要目的。好了，废话不多说，大家直接看下文吧。
前提准备 (关闭防火墙，selinux，安装libaio)
```
shell> chkconfig --level 2345 iptables off
shell> service iptables stop
shell> vi /etc/selinux/config
SELINUX=disabled
```

shell> yum install libaio

1. 配置用户属组 (MysqL用户不需要登录操作系统)

shell> groupadd MysqL
shell> useradd -r -g MysqL -s /bin/false MysqL

2. 解压二进制软件

shell> cd /usr/local
shell> mv ~/MysqL-5.7.21-linux-glibc2.12-x86_64.tar.gz ./

shell> tar zxvf MysqL-5.7.21-linux-glibc2.12-x86_64.tar.gz
or
shell> gunzip < MysqL-5.7.21-linux-glibc2.12-x86_64.tar.gz | tar xvf -

shell> mv MysqL-5.7.21-linux-glibc2.12-x86_64 MysqL-5.7.21

3. 修改软件权限创建链接

shell> chmod -R 750 ./MysqL-5.7.21
shell> chown -R MysqL:MysqL ./MysqL-5.7.21
shell> ln -s /usr/local/MysqL-5.7.21 MysqL

4. 创建MysqL数据目录 (提前touch日志文件，否则启动的时候会报错)

shell> mkdir -p /MysqL/{data,log,binlog}
shell> chown -R MysqL:MysqL /MysqL/
shell> touch /MysqL/log/MysqLd.log
shell> chown MysqL:MysqL /MysqL/log/MysqLd.log

5. 编辑数据库云服务器参数 (指定数据初始化目录，也可以通过命令行指定初始化目录)

shell> vi /etc/my.cnf
[MysqLd]
datadir=/MysqL/data
socket=/MysqL/log/MysqL .sock

[MysqLd_safe]
log_error=/MysqL/log/MysqLd.log
pid_file=/MysqL/log/MysqLd.pid

6. 初始化数据库

shell> cd MysqL
shell> bin/MysqLd --initialize --user=MysqL (m3gfb<1gKDZ%)
shell> bin/MysqL_ssl_rsa_setup
shell> bin/MysqLd_safe --user=MysqL &

7. 修改默认root口令

[root@crmdb1 MysqL]# MysqL -u root -p -S /MysqL/log/MysqL .sock
MysqL> ALTER USER 'root'@'localhost' IDENTIFIED BY 'oracle';
MysqL> FLUSH PRIVILEGES;

8. 关闭数据库
`[root@crmdb1 MysqL]# bin/MysqLadmin -u root -p -S /MysqL/log/MysqL.sock shutdown`

9. 修改环境变量

shell> vi ~/.bash_profile
export PATH=/usr/local/MysqL/bin:$PATH
export MysqL_PS1="(\u@\h) [\d]> "

[root@crmdb1 MysqL]# . ~/.bash_profile

10. 配置MysqL服务

shell> cp support-files/MysqL.server /etc/init.d/MysqL
shell> chkconfig --add MysqL
shell> chkconfig --level 2345 MysqL on

11. 编辑数据库客户端参数

[client]
host=localhost
user=root
password=oracle
socket=/MysqL/log/MysqL .sock

12. 启动MysqL服务
`shell> service MysqL start`

13. 登录数据库验证

shell> MysqL
(root@localhost) [(none)]> show databases;

错误解决：
1.

2018-03-15T13:38:06.902460Z 0 [ERROR] SSL error: Unable to get private key from 'server-key.pem'
2018-03-15T13:38:06.902470Z 0 [Warning] Failed to set up SSL because of the following SSL library error: Unable to get private key

MysqL 用户没有权限访问'server-key.pem'文件，修改权限后错误解决：
[root@crmdb1 security]# cd /MysqL/data/
[root@crmdb1 data]# ls -la server-key.pem
-rw------- 1 root root 1679 Mar 15 21:24 server-key.pem
[root@crmdb1 data]# chmod 644 server-key.pem
[root@crmdb1 data]# service MysqL restart

2018-03-15T14:29:38.605619Z 0 [Note] Found ca.pem, server-cert.pem and server-key.pem in data directory. Trying to enable SSL support using them.
null

2.
2018-03-15T13:38:06.767757Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_time
stamp server option (see documentation for more details).

通过设置参数解决该告警：
explicit_defaults_for_timestamp=1

Note
explicit_defaults_for_timestamp is itself deprecated because its only purpose is to permit control over deprecated TIMESTAMP behaviors that are to be removed in a future MysqL release. When removal of those behaviors occurs, explicit_defaults_for_timestamp will have no purpose and will be removed as well.
