MySQL 5.7.21 在 OEL6.9 平台上的二進位安裝

標籤：MySQL5.7   OEL6.9   MySQL二進位安裝   

前提準備 (關閉防火牆，selinux，安裝libaio)

shell> chkconfig --level 2345 iptables offshell> service iptables stopshell> vi /etc/selinux/configSELINUX=disabled

shell> yum install libaio

1. 配置使用者屬組 (MySQL使用者不需要登入作業系統)

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

2. 解壓二進位軟體

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. 修改軟體許可權建立連結

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. 建立MySQL資料目錄 (提前touch記錄檔，否則啟動的時候會報錯)

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. 編輯資料庫伺服器參數 (指定資料初始化目錄，也可以通過命令列指定初始化目錄)

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. 初始化資料庫

shell> cd mysql
shell> bin/mysqld --initialize --user=mysql (m3gfb<1gKDZ%)
shell> bin/mysql_ssl_rsa_setup
shell> bin/mysqld_safe --user=mysql &

7. 修改預設root口令

[[email protected] mysql]# mysql -u root -p -S /mysql/log/mysql.sock
mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘oracle‘;
mysql> FLUSH PRIVILEGES;

8. 關閉資料庫`[[email protected] mysql]# bin/mysqladmin -u root -p -S /mysql/log/mysql.sock shutdown`9. 修改環境變數

shell> vi ~/.bash_profile
export PATH=/usr/local/mysql/bin:$PATH
export MYSQL_PS1="(\[email protected]\h) [\d]> "

[[email protected] mysql]# . ~/.bash_profile

10. 配置MySQL服務

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

11. 編輯資料庫用戶端參數

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

12. 啟動MySQL服務`shell> service mysql start`13. 登入資料庫驗證

shell> mysql
([email protected]) [(none)]> show databases;

錯誤解決：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使用者沒有許可權訪問‘server-key.pem‘檔案，修改許可權後錯誤解決：
[[email protected] security]# cd /mysql/data/
[[email protected] data]# ls -la server-key.pem
-rw------- 1 root root 1679 Mar 15 21:24 server-key.pem
[[email protected] data]# chmod 644 server-key.pem
[[email protected] data]# service mysql restart

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).

通過設定參數解決該警示：
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.
