mysql 7.5.8 服務無法啟動 服務沒有報告任何錯誤

你安裝的mysql位置不是c盤的話應該出現此問題。

1.打開bin下的mysql_config.pl文件，查找以下幾行，把目錄改成你安裝mysql的目錄即可。

my $ldata   = 'C:/Program Files/MySQL/MySQL Server 5.7/data';
my $execdir = 'C:/Program Files/MySQL/bin';
my $bindir  = 'C:/Program Files/MySQL/bin';

my $pkglibdir = fix_path('C:/Program Files/MySQL/lib',"libmysql/relwithdebinfo",
                         "libmysql/release","libmysql/debug","lib/mysql","lib");

my $pkgincludedir = fix_path('C:/Program Files/MySQL/include', "include/mysql", "include");

我是安裝在D盤所以改成了如一下幾行：

my $ldata   = 'D:/Program Files/MySQL/MySQL Server 5.7/data';
my $execdir = 'D:/Program Files/MySQL/bin';
my $bindir  = 'D:/Program Files/MySQL/bin';

my $pkglibdir = fix_path('D:/Program Files/MySQL/lib',"libmysql/relwithdebinfo",
                         "libmysql/release","libmysql/debug","lib/mysql","lib");

my $pkgincludedir = fix_path('D:/Program Files/MySQL/include', "include/mysql", "include");

 

2.以管理員身份運行cmd，輸入:mysqld -install(如果不用管理員身份運行，將會因為權限不夠而出現錯誤：Install/Remove of the Service Denied!)

3.運行mysqld  --initialize（標題問題所在，若沒有init則不存在data目錄，自然無法啟動成功）

4.安裝成功后就要啟動服務了，繼續在cmd中輸入:net start mysql,服務啟動成功！

5.服務啟動成功之后，就可以登錄了

在mysql目錄下搜索*.err，以文本形式打開才能看到如下內容：

016-02-25T15:09:43.033062Z 1 [Note] A temporary password is generated for root@localhost: >mso<k70mrWe

紅色字母即為第一次的登陸密碼，記得加雙引號。

輸入mysql -u root -p回撤輸入密碼即可登錄

6.修改密碼

格式：mysql> set password for 用戶名@localhost = password('新密碼');
