MySQL报错:The server quit without updating PID file的解决思路与方法

今天在学习mysql 二进制日志的时候需要在编辑my.cnf的文件，产生的一系列报错，个人的排错思路和方法，仅供参考。

重启damon、重启mysql 发现报错

Starting MySQL. ERROR! The server quit without updating PID file (/usr/local/mysql/data/mysqld.pid).

发现注释这三行配置之后发现可以正常启动，那么问题就出现在这三行代码上

log-bin = mysql-bin  
#binlog_expire_logs_seconds = 600
#max_binlog_size = 200M

查询日志发现报错：You have enabled the binary log, but you haven't provided the mandatory server-id. Please refer to the proper server start-up parameters documentation#您已经启用了二进制日志，但是没有提供必需的服务器id。请参考适当的服务器启动参数文档

经过百度发现：MySQL 5.7.3以后版本必须配置server-id，否则无法启用MySQL二进制日志

尝试启动 在my.cnf中添加 server-id = 1   唯一的服务辨识号,数值位于 1 到 2^32-1之间。此值在master和slave上都需要设置。

如果 “master-host” 没有被设置,则默认为1, 但是如果忽略此选项,MySQL不会作为master生效

添加参数，并尝试启动。 

发现又报错：Can't connect to local MySQL server through socket '/tmp/mysql.sock'

mysql的连接方式有两种:一种是TCP/IP、一种是socket连接

mysql.sock的作用是程序与mysqlserver处于同一台机器，发起本地连接时可用。 

连接localhost通常通过一个Unix域套接字文件进行，一般是/tmp/mysql.sock。

如果套接字文件被删除了，本地客户就不能连接。/tmp 文件夹属于临时文件，随时可能被删除。

每次mysql 启动的时候，都会生成一个mysql.sock 的文件，

socket = /var/lib/mysql/mysql.sock   建议将sock文件移动至下var/lib/mysql/  

尝试重新启动 发现还是报错 Starting MySQL. ERROR! The server quit without updating PID file

排错：

 1. 检查目录权限    

 2. selinux是否关闭  

 3. 检查my.cnf参数 port,datadir,basedir,socket 是否配置正常

排错发现是我配置sock目录时候，并没有给予权限

chown -R mysql:mysql /var/lib/mysql/   #设置权限，并查看
ls -alh | grep mysql
drwxr-xr-x.  2 mysql   mysql      6 Sep 14 16:19 mysql

再次尝试启动mysql 发现还是报错：Starting MySQL. ERROR! The server quit without updating PID file (/usr/local/mysql/data/mysqld.pid).

1. tail -f /usr/local/mysql/data/mysql.err  /查询MySQL自带的日志文件mysql.err

 #发现没有关键错误信息

 2. tail /var/log/messages  #记录了绝大多数的系统日志

 发现关键字 unknown variable 未知的变量  binlog_expire_logs_seconds

 我照着视频里面的单词一个个敲，不是我敲错。尝试寻找度娘

在mysql 8.0版本中新增了binlog_expire_logs_seconds，该参数表示binlog的失效日期单位秒。

8.0之前的版本，binlog的失效日志用expire_logs_days来配置，单位是天。

参考链接：mysql 8 新特性之binlog_expire_logs_seconds

因为我是学习了8.0和5.7版本的Mysql都有在学习，win端使用的是8.0 linux安装的是5.7

所以是我mysql版本的问题导致。更改参数 

[mysqld]
user = mysql
port = 3306
basedir = /usr/local/mysql  
# 创建目录
datadir = /usr/local/mysql/data   
# 数据库目录
pid-file = /usr/local/mysql/data/mysqld.pid 
# mysql进程
log-error = /usr/local/mysql/data/mysql.err   
# 错误日志
socket = /var/lib/mysql/mysql.sock
# 可以socket文件方式登录mysql
log-bin = /usr/local/mysql/data/bin-log/mysql-bin.log
server-id = 1
#binlog_expire_logs_seconds = 600
max_binlog_size = 200M
#Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links = 0
#禁止符号链接以防各种安全风险
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd
 
# [mysqld_safe]
 
#
# include all files from the config directory
#
!includedir /etc/my.cnf.d
explicit_defaults_for_timestamp=true

再再再再次尝试启动MySQL

尝试登录MySQL 发现又报错：错误2002 (HY000):无法通过套接字'/tmp/ MySQL连接到本地MySQL服务器

[root@master lib]# mysql -u root -p
