一小时前我安装了mysql社区版。我不知道是否与此有关。我也有mamp安装在我的电脑上，但我关闭了它，所以我不认为端口3306是占领。下面是xampp mysql错误日志

2018-10-26 23:53:31 160c InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED. This option may be removed in future releases, together with the option innodb_use_sys_malloc and with the InnoDB's internal memory allocator.

InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

这是配置文件，请检查是否有错误的设置我做了。提前谢谢大家

# 

# 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>
