#解壓安裝包
[[email protected] Mysql]# tar -xf mysql-5.7.18.tar.gz
[[email protected] Mysql]# tar -xf mysql-boost-5.7.18.tar.gz
注意：要加壓兩個壓縮檔案，當解壓boots時，若mysql安裝包與boots在同一目錄下，解壓後會自動放到安裝包內，若兩個壓縮包不在同一路徑下，需要將boots解壓到mysql安裝包內

#檢查是否掛載映象，若無掛載，手工掛載即可

#設定啟動指令碼，開機自啟動
[[email protected] mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
[[email protected] mysql]# chmod +x /etc/init.d/mysql
[[email protected] mysql]# chown -R mysql:mysql /usr/local/mysql/

#修改etc目錄下my.cnf檔案，並初始化資料庫
修改內容如下：
[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/usr/local/mysql/mysqld.sock

[mysqld_safe]
log-error=/usr/local/mysql/mysql.log
pid-file=/usr/local/mysql/mysql.pid

[mysql]
no-auto-rehash
socket=/usr/local/mysql/mysqld.sock

儲存並退出

初始化資料庫
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

注意：初始化後，自動生成密碼

#配置環境變數並啟動服務
[[email protected] mysql]# vim /etc/profile
編輯環境變數，輸入以下內容：
PATH=/usr/local/mysql/bin:$PATH
export PATH
重新整理生效
[[email protected] mysql]# source /etc/profile

#啟動資料庫
[[email protected] mysql]# service mysql start

注意：若是啟動時出現這個問題，是mysql.log沒有，手工建立一個

Starting MySQL.2018-06-15T17:09:16.784027Z mysqld_safe error: log-error set to ‘/usr/local/mysql/mysql.log’, however file don’t exists. Create writable for user ‘mysql’.
ERROR! The server quit without updating PID file (/usr/local/mysql/data/kvm122102.pid).

手工建立mysql.log步驟如下：
