mysql5.7二进制安装（linux下mysql二进制安装附资料及配置文件）

一、准备资料

• 资料
  
• 环境

  操作系统 CentOS7.6
  数据库：mysql-5.7.29-linux-glibc2.12-x86_64（二进制文件）

二、准备工作

• 安装mysql依赖扩展

  yum -y install ncurses-devel  libaio-devel
  

• 创建mysql组及用户

  [root@NGINX ~]# groupadd mysql
  [root@NGINX ~]# useradd -s /sbin/nologin -g mysql -M mysql
  

• 上传mysql文件至家目录
  上传文件并解压

  [root@NGINX ~]# tar -zxvf mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz 
  [root@NGINX ~]# mv mysql-5.7.29-linux-glibc2.12-x86_64 /usr/local/mysql
  ##
  [root@NGINX ~]# mkdir /usr/local/mysql/data -p
  [root@NGINX ~]# chown mysql.mysql /usr/local/mysql/data/
  [root@NGINX ~]# chown mysql.mysql /usr/local/mysql/ -R
  
  

三、安装

• 初始化数据库

  [root@NGINX ~]#/usr/local/mysql/bin/mysqld --initialize \
  --basedir=/usr/local/mysql/ \
  --datadir=/usr/local/mysql/data/ --user=mysql
  

• 提示如下说明初始化成功

• 配置环境变量

[root@NGINX ~]# echo 'export PATH=/usr/local/mysql/bin:$PATH'>>/etc/profile
[root@NGINX ~]# source /etc/profile

• 配置服务

[root@NGINX ~]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
[root@NGINX ~]# service mysql start
Starting MySQL.2020-02-03T17:28:22.352928Z mysqld_safe error: log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.
 ERROR! The server quit without updating PID file (/var/lib/mysql/NGINX.pid).
###添加些日志权限修改pid文件写权限

• 故障处理全过程

[root@NGINX ~]# service mysql start
Starting MySQL.2020-02-03T17:28:22.352928Z mysqld_safe error: log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.
 ERROR! The server quit without updating PID file (/var/lib/mysql/NGINX.pid).
[root@NGINX ~]# mkdir /var/log/mariadb/ -p
[root@NGINX ~]# echo ''>/var/log/mariadb/mariadb.log|xargs chown mysql.mysql
chown: missing operand after ‘mysql.mysql’
Try 'chown --help' for more information.
[root@NGINX ~]# ^C
[root@NGINX ~]# mkdir /var/log/mariadb/ -p
[root@NGINX ~]# echo ''>/var/log/mariadb/mariadb.log
[root@NGINX ~]# chown mysql.mysql /var/log/mariadb/mariadb.log
[root@NGINX ~]# chown mysql.mysql /var/lo
local/ lock/  log/   
[root@NGINX ~]# chown mysql.mysql /var/log/mysql
chown: cannot access ‘/var/log/mysql’: No such file or directory
[root@NGINX ~]# mkdir /var/log/mysql
[root@NGINX ~]# chown mysql.mysql /var/log/mysql
[root@NGINX ~]# service mysql start

[root@NGINX ~]# mkdir /var/lib/mysql

[root@NGINX ~]# service mysql start
Starting MySQL..... ERROR! The server quit without updating PID file (/var/lib/mysql/NGINX.pid).
###还是启动不起来发现my.cnf中datadir没有修改将datadir=/var/lib/mysql
###改成/usr/local/mysql/data
[root@NGINX ~]# vi /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/data
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# 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]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

#
# include all files from the config directory
#
#!includedir /etc/my.cnf.d
"/etc/my.cnf" 19L, 578C written
[root@NGINX ~]# service mysql start
Starting MySQL. SUCCESS! 

• 服务已经成功起来
  

• 连接数据库
  依旧很坎坷
