centos7安裝mysql5.7解壓縮版
CentOS7 安裝Mysql5.7(解壓縮版)
2.檢查庫檔案是否存在，如有刪除。
[root@localhost Desktop]$ rpm -qa | grep mysql
mysql-libs-5.1.52-1.el6_0.1.x86_64
[root@localhost ~]$ rpm -e mysql-libs-5.1.52.x86_64 --nodeps
[root@localhost ~]$3.檢查mysql組和使用者是否存在，如無建立。
[root@localhost ~]$ cat /etc/group | grep mysql
mysql:x:490:
[root@localhost 以上為預設存在的情況，如無，執行新增命令：
[root@localhost ~]$groupadd mysql
[root@localhost ~]$useradd -r -g mysql mysql
//useradd -r引數表示mysql使用者是系統使用者，不可用於登入系統。4.解壓TAR包，更改所屬的組和使用者
[[email protected] ~]$ cd /usr/local/
[[email protected] local]$ tar xvf mysql-5.7 5.安裝和初始化資料庫
[[email protected]alhost mysql]$bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

2016-06-01 15:23:30 [WARNING] The bootstrap log isn't empty:

[root@localhost mysql]$
[root@localhost mysql]$ cp -a ./support-files/my-default.cnf /etc/my.cnf
[root@localhost mysql]$ cp -a ./support-files/mysql.server /etc/init.d/mysqld[root@localhost mysql]$ cd bin/

[root@localhost bin]$6.初始化密碼
mysql5.7會生成一個初始化密碼，而在之前的版本首次登陸不需要登入。
[[email protected] bin]$ cat /root/.mysql_secret
# Password set for user '[email protected]' at 2016-06-01 15:23:25

遇到的問題：
找不到mysql.sock，mysql.sock丟失問題解決方法
連線Mysql時，機器上找不到mysql.sock檔案你可以簡單地通過重啟伺服器重新建立得到它。因為伺服器在啟動時重新建立它。[[email protected] mysql-5.7.13]# ./bin/mysql_install_db --user=mysql
2016-06-26 02:47:09 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2016-06-26 02:47:09 [ERROR] The data directory needs to be specified.
解決：需要新建data目錄，指定安裝目錄(在非預設目錄時需要指定，預設路徑：/usr/local/mysql，同時需要指定./support-files/mysql.server中的basedir和datadir為相應路徑)。
[[email protected] mysql-5.7.13]# ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql-5.7.13/ --datadir=/usr/local/mysql-5.7.13/data/

以上報錯均因未在mysql.server中指定自定義的路徑。
若是還提示已經有data檔案了 刪除了它，新建即可
