MYSQL 5.7.17 安裝：
軟件獲取：
官網下載 mysql-advanced-5.7.17-linux-glibc2.5-x86_64.tar.gz
解壓安裝：
解壓 mysql-advanced-5.7.17-linux-glibc2.5-x86_64.tar.gz
tar -xvzf mysql-advanced-5.7.17-linux-glibc2.5-x86_64.tar.gz
將解壓的安裝文件拷貝到安裝目錄（可自定義）
[root@VMOS01 mysql]# cp -r mysql-advanced-5.7.17-linux-glibc2.5-x86_64 /usr/local/
[root@VMOS01 mysql]# cd /usr/local
[root@VMOS01 local]# mv mysql-advanced-5.7.17-linux-glibc2.5-x86_64 mysql-5.7.17
建立軟鏈接：
[root@VMOS01 local]# ln -s mysql-5.7.17 mysql
[root@VMOS01 local]# ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql
添加 MYSQL 運行用戶：
[root@VMOS01 local]# useradd -r -M -u 496 -s /sbin/nologin mysql
將軟件、目錄賦權給運行用戶 mysql:
[root@VMOS01 local]# chown -R mysql.mysql /usr/local/mysql-5.7.17/
[root@VMOS01 local]# chown -R mysql.mysql /usr/local/mysql
[root@VMOS01 local]# chgrp -R mysql /usr/local/mysql-5.7.17/
初始化 mysql db:
[root@VMOS01 local]# cd /usr/local/mysql
[root@VMOS01 bin]# cd ..
[root@VMOS01 mysql]# ./bin/mysql_install_db –user=mysql –basedir=/usr/local/mysql/ –datadir=/usr/local/mysql/data/
2017-04-09 22:38:11 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld –initialize
2017-04-09 22:38:20 [WARNING] The bootstrap log isn t empty:
2017-04-09 22:38:20 [WARNING] 2017-04-10T05:38:12.530858Z 0 [Warning] –bootstrap is deprecated. Please consider using –initialize instead
mysql5.7 新特性：由上面可以看出， mysql_install_db 已經不再推薦使用了，建議改成 mysqld –initialize 完成實例初始化。
[root@VMOS01 mysql]# ./bin/mysqld –defaults-file=/etc/my.cnf –user=mysql –basedir=/usr/local/mysql/ –datadir=/usr/local/mysql/data/ –initialize
2017-04-10T06:12:09.706181Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use –explicit_defaults_for_timestamp server option (see documentation for more details).
2017-04-10T06:12:11.269373Z 0 [Warning] InnoDB: New log files created, LSN=45790
2017-04-10T06:12:11.496771Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.

2017-04-10T06:12:11.566539Z 0 [Warning] Gtid table is not ready to be used. Table mysql.gtid_executed cannot be opened.
2017-04-10T06:12:12.196832Z 0 [Warning] CA certificate ca.pem is self signed.
2017-04-10T06:12:12.439938Z 1 [Note] A temporary password is generated for root@localhost: S8t6ikvw t1E【記住初始密碼】
啟動 mysql：
[root@VMOS01 support-files]# ./mysql.server start
Starting MySQL SUCCESS!
***
將 mysql 添加到系統服務管理：
[root@VMOS01 support-files]# cp -v mysql.server /etc/init.d
`mysql.server – `/etc/init.d/mysql.server
[root@VMOS01 support-files]# cd /etc/init.d
[root@VMOS01 init.d]# chkconfig –add mysql.server
[root@VMOS01 init.d]# service mysql.server status
SUCCESS! MySQL running (33215)
[root@VMOS01 init.d]# service mysql.server stop
Shutting down MySQL.. SUCCESS!
[root@VMOS01 init.d]# service mysql.server start
Starting MySQL. SUCCESS!
注意點：
編輯 my.cnf 讓本地命令行登陸管理 mysql，不會提示找不到 mysql.sock 文件錯誤：
[root@VMOS01 mysql]# more /etc/my.cnf
[client]
socket=/var/lib/mysql/mysql.sock
[root@VMOS01 init.d]# mysql -uroot -p
Enter password:【輸入初始 DB 的密碼】
**************************
需要更改 root@localhost 初始密碼：
第一次登陸 mysql, 需要更改 root@localhost 密碼，否則會出現如下錯誤：
[root@VMOS01 support-files]# mysql -ur0ot -p
Enter password:
mysql show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql alter user root@localhost identified by Root15()
mysql show databases;
+——————–+
| Database |

至此 mysql 5.7.17 安裝完成。
