1.從官網下載mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz

2.建立mysql的使用者組/使用者，data目錄及其使用者目錄

#mkdir /usr/local/mysql #在/usr/local資料夾下建立mysql檔案

#mkdir /usr/local/mysql/data #在mysql資料夾下建立data檔案

#groupadd mysql #建立一個名為mysql的使用者組

#useradd -g mysql -d #在使用者組下 建立使用者

3.解壓安裝包並將解壓包裡的內容拷貝到mysql的安裝目錄/usr/local/mysql

#tar -zxvf mysql-5.7.18-linux-glib2.5-x86_64.tar.gz #解壓檔案

#cd mysql-5.7.18-linux-glib2.5-x86_64 #進入解壓檔案

#mv * /usr/local/mysql #移動到之前的mysql檔案下

4.初始化mysql資料庫

#cd /usr/local/myslq

#./bin/mysql –user=mysql –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data

記住上面的隨機密碼，如上mjT,#x_5sW修改密碼時需要用到
5. 檢測下是否能啟動mysql服務
#cd /usr/local/myslq
#./support-files/mysql.server start
Starting MySql..ok!
以上是正常情況，啟動如果出錯，會出現下面資訊
# ./support-files/mysql.server start
./support-files/mysql.server: line 276: cd: /usr/local/mysql: No such file or directory
Starting MySQL ERROR! Couldn't find MySQL server (/usr/local/mysql/bin/mysqld_safe)
這時候我們需要修改/support-files/mysql.server檔案的basedir和datadir目錄路徑為我們環境所在的mysql的basedir和datadir路徑， 如下：

# vim support-files/mysql.server
————————–
…
basedir=/home/mysql
datadir=/home/mysql/data
…
————————–
# ./support-files/mysql.server start
start Starting MySQL.. OK!

6. 建立配置檔案 
a．將預設生成的my.cnf備份
# mv /etc/my.cnf /etc/my.cnf.bak
b、進入mysql的安裝目錄支援檔案目錄
# cd /home/mysql/support-files
c、拷貝配置檔案模板為新的mysql配置檔案,
# cp my-default.cnf /etc/my.cnf
d、設定編碼，可按需修改新的配置檔案選項， 不修改配置選項， mysql則按預設配置引數執行. 修改配置檔案/etc/my.cnf， 設定編碼為utf8以防亂碼
# vim /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data

character_set_server=utf8
init_connect='SET NAMES utf8'

[client]
default-character-set=utf8
有的時候使用這個命令後，前3步有問題的這裡可能my.cnf檔案是空的，這個不要緊，既然沒有生成，那麼就自己編輯

7.配置mysql服務開機自動啟動 
#cp/usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
# 拷貝啟動檔案到/etc/init.d/下並重命令為mysqld
# chmod 755 /etc/init.d/mysqld # 增加執行許可權
# chkconfig –list mysqld # 檢查自啟動項列表中沒有mysqld
# chkconfig –add mysqld # 如果沒有就新增mysqld：
# chkconfig mysqld on # 用這個命令設定開機啟動：
8. mysql服務的啟動/重啟/停止 
# service mysqld start # 啟動服務
# service mysqld restart # 重啟服務
# service mysqld stop # 停止服務
9. 初始化mysql使用者root的密碼

#mysql -u root -p
