ubuntu16.04下的MySQL離線安裝

正常狀況下，ubuntu下在線安裝mysql都是採用apt方式，幾句命令就搞定了，網上教程不少，這裏就很少說了，命令以下：

apt-get install mysql-server

apt-get install mysql-client

apt-get install libmysqlclient-dev
複製代碼

我這裏要介紹的是非正常狀況，因爲咱們服務器的緣由，沒法隨意鏈接外網，也就不能使用apt在線安裝方式，只能使用離線安裝，網上搜了一下，相關教程不是不少，這裏介紹一下個人操做。

首先是相關文件下載，下載以後上傳到服務器，服務器環境：ubuntu16.04 64位

mysql免安裝包：mirrors.sohu.com/mysql/MySQL…

依賴包：archive.ubuntu.com/ubuntu/pool…

1. 安裝依賴

dpkg -i libaio1_0.3.110-2_amd64.deb
複製代碼

2. 建立目錄存放數據庫文件data和日誌log

mkdir /mysql /mysql/data /mysql/log
複製代碼

3. 解壓mysql

tar zxf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
複製代碼

4. 移到默認目錄

mv mysql-5.7.17-linux-glibc2.5-x86_64  /usr/local/mysql
複製代碼

5. 增長用戶和組

groupadd mysql

useradd -g mysql mysql
複製代碼

6. 修改目錄權限

chown -R mysql:mysql /usr/local/mysql /mysql
複製代碼

7. 建立配置文件

vi /etc/my.cnf

[client]
port = 3306
socket = /tmp/mysql.sock
[mysqld]
server_id=10
port = 3306
user = mysql
socket = /tmp/mysql.sock
basedir = /usr/local/mysql
datadir = /mysql/data
pid-file = /mysql/data/mysql.pid
max_connections = 1000
max_connect_errors = 1000
table_open_cache = 1024
max_allowed_packet = 128M
open_files_limit = 65535
#####====================================[innodb]==============================
innodb_buffer_pool_size = 1024M
innodb_file_per_table = 1
innodb_write_io_threads = 4
innodb_read_io_threads = 4
innodb_purge_threads = 2
innodb_flush_log_at_trx_commit = 1
innodb_log_file_size = 512M
innodb_log_files_in_group = 2
innodb_log_buffer_size = 16M
innodb_max_dirty_pages_pct = 80
innodb_lock_wait_timeout = 30
innodb_data_file_path=ibdata1:1024M:autoextend
#####====================================[log]==============================
log_error = /mysql/log/mysql-error.log
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /mysql/log/mysql-slow.log
sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
複製代碼

8. 添加執行權限

chmod +x /usr/local/mysql/bin/*
複製代碼

9. 配置環境變量

vim /etc/profile

export PATH=$PATH:/usr/local/mysql/bin

source /etc/profile
複製代碼

10. 配置啓動文件

cp /usr/local/mysqlsupport-files/mysql.server /etc/init.d/mysql
複製代碼

11. 系統默認啓動

update-rc.d mysql defaults
複製代碼

12. 初始化數據庫（5.7.6以後的版本初始化數據庫再也不使用mysql_install_db）

mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/home/fabric/mysql/data --innodb_undo_tablespaces=3 --explicit_defaults_for_timestamp
複製代碼

13. 啓動服務

cd /usr/local/mysql/support-files

./mysql.server start

./mysql.server status（查看狀態，若是顯示【 * MySQL running】則說明啓動成功）
複製代碼

14. 能夠在/mysql/log/mysql-error.log中查看root用戶的初始化密碼

A temporary password is generated for root@localhost: *****************
複製代碼

15. 修改root密碼和遠程訪問權限

mysql -u root -p
輸入14中查看的默認密碼

mysql>SET PASSWORD = PASSWORD('your new password');
mysql>update mysql.user set authentication_string=password('your new password') where user='root';
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'your new password';
mysql>FLUSH PRIVILEGES;
複製代碼

大功告成！！！
