WampServer - MySQL 服务未启动

WampServer - MySQL service doesn't start

提问by eeadev

I cannot use WAMP properly as MySQL service is not starting neither when I click on wampserver/mysql/StartResume Service.

我无法正确使用 WAMP，因为当我单击 wampserver/mysql/StartResume 服务时，MySQL 服务也没有启动。

Please note:

请注意：

1. WampServer icon is orange
2. I can use MySQL console and see all of my databases
3. PhpMyAdmin works when I browse on http://localhost/phpmyadmin
4. innodb_additional_mem_pool_sizeis not in my.ini
5. Mysql.log is emptystrong text
6. innodb_force_recovery = 1does not change anything

1. WampServer 图标为橙色
2. 我可以使用 MySQL 控制台查看我的所有数据库
3. 当我浏览http://localhost/phpmyadmin 时，PhpMyAdmin 工作
4. innodb_additional_mem_pool_size不在my.ini 中
5. Mysql.log 是空的强文本
6. innodb_force_recovery = 1不会改变任何东西

What else shall I try?

我还要尝试什么？

#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended
#log-bin=mysql-bin

# Point the following paths to different dedicated disks
#tmpdir     = /tmp/

In your question you say :-

在您的问题中，您说：-

• I can use MySQL console and see all of my databases*

• PhpMyAdmin works when I browse on http://localhost/phpmyadmin*

• 我可以使用 MySQL 控制台查看我的所有数据库*

• 当我浏览http://localhost/phpmyadmin* 时，PhpMyAdmin 工作

In that case MySQL must be running

在这种情况下，MySQL必须正在运行

So that makes me think that you have got a second MySQL Server running on your system.

所以这让我觉得你的系统上运行了第二个 MySQL 服务器。

MySQL can be installed as part of some other tools/apps. If that is the case they normally set the service name to MYSQLand set it to start automaticallyso it is probably running before you get to start WAMPServer and therefore blocking port 3306. The WAMPServer MySQL instance is called wampmysqld(or wampmysqld64if you run the 64bit WAMPSever). Have a look at what services are running using the services.mscsnapin.

MySQL 可以作为一些其他工具/应用程序的一部分安装。如果是这种情况，他们通常将服务名称MYSQL设置为并将其设置为启动，automatically因此它可能在您启动 WAMPServer 之前运行，因此会阻塞端口 3306。调用 WAMPServer MySQL 实例wampmysqld（或者wampmysqld64如果您运行 64 位 WAMPSever）。使用services.msc管理单元查看正在运行的服务。

WINDOWS KEY + R
enter services.msc
Press the OK button    

You only need one MYSQL Server to serve many databases, so you need to decide which one you want to use. If you decide to remove the non WAMPServer MySQL then dont forget to backup your databases before removing the old MySQL

您只需要一台 MYSQL Server 即可为多个数据库提供服务，因此您需要决定要使用哪一台。如果您决定删除非 WAMPServer MySQL，那么在删除旧 MySQL 之前不要忘记备份您的数据库

In my case the problem was other multiple instances of MySQL. I have installed MySQL Workbench from Oracle. Turns out I could only have one MySQL service running at a time.

在我的情况下，问题是其他多个 MySQL 实例。我已经从 Oracle 安装了 MySQL Workbench。结果我一次只能运行一个 MySQL 服务。

Okay, I did some research online and it mentioned that you need to do the following:

好的，我在网上做了一些研究，它提到您需要执行以下操作：

Search for mysql-bin.index file, delete it, then restart MySQL

搜索 mysql-bin.index 文件，删除它，然后重启 MySQL

I had exactly the same issue with my new Wamp 3.1.9 installation. Somehow the datadir was missing in mysql5.7.26. A quick fix was to run this command from bindir: mysqld --initialize-insecure

我的新 Wamp 3.1.9 安装遇到了完全相同的问题。不知何故，data目录在mysql5.7.26. 快速修复是从bin目录运行此命令：mysqld --initialize-insecure
