linux centos离线安装mysql5.7详细方法
文章来源https://www.cnblogs.com/yy3b2007com/p/10497787.html感谢分享centos7下使用mysql离线安装包安装mysql5.7
服务器环境：
centos7 x64
需要安装mysql5.7+
一、卸载CentOS7系统自带mariadb
# 查看系统自带的Mariadb
# rpm -qa|grep mariadb
mariadb-libs-5.5.44-2.el7.centos.x86_64
# 卸载系统自带的Mariadb
# rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64
# 删除etc目录下的my.cnf
# rm /etc/my.cnf二、检查mysql是否存在
# 检查mysql是否存在
# rpm -qa | grep mysql
# 三、查看用户和组是否存在1）检查mysql组合用户是否存在
# 检查mysql组和用户是否存在，如无则创建
# cat /etc/group | grep mysql
# cat /etc/passwd | grep mysql # 查询全部用户（只是做记录，没必要执行）
# cat /etc/passwd|grep -v nologin|grep -v halt|grep -v shutdown|awk -F ":" '{print $1 "|" $3 "1" $4}' | more

#2）若不存在，则创建mysql组和用户
# 创建mysql用户组
# groupadd mysql
# 创建一个用户名为mysql的用户，并加入mysql用户组
# useradd -g mysql mysql
# 制定password 为111111
# passwd mysql
Changing password for user mysql.
New password:
BAD PASSWORD: The password is a palindrome
Retype new password:
passwd: all authentication tokens updated successfully.四、下载mysql离线安装包tar文件
官网下载地址：https://dev.mysql.com/downloads/mysql/5.7.html#downloads
版本选择，可以选择一下两种方式：
1）使用Red Hat Enterprise Linux
Select Version:5.7.25
Select Operating System:Red Hat Enterprise Linux / Oracle Linux
Select OS Version:Red Hat Enterprise Linux 7 / Oracle Linux 7 (x86, 64-bit)
列表中下载：
Compressed TAR Archive：(mysql-5.7.25-el7-x86_64.tar.gz)
2）使用Linux - Generic
Select Version:5.7.25
Select Operating System:Linux - Generic
Select OS Version:Linux - Generic (glibc 2.12) (x86, 64-bit)
列表中下载：
Compressed TAR Archive：(mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz)【本文中使用的是这个版本】
注意：上边两种方式找mysql离线安装包的方式都可以。
五、上传第四步下载的mysql TAR包
# 进入/usr/local/文件夹
# cd /usr/local/
# 上传mysql TAR包
# rz
# 解压mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz
# ls

# ls

# 更改所属的组和用户
# cd /usr/local/
# chown -R mysql mysql/
# chgrp -R mysql mysql/
# cd mysql/
# mkdir data
# chown -R mysql:mysql data七、在/etc下创建my.cnf文件
# 进入/usr/local/mysql文件夹下
# cd /usr/local/mysql
# 创建my.cnf文件
# touch my.cnf #或者cd ''>my.conf
# 编辑my.cnf
# vi my.conf
socket=/var/lib/mysql/mysql.sock
# set mysql client default chararter
default-character-set=utf8
socket=/var/lib/mysql/mysql.sock
# set mysql server port
port = 3323 #默认是3306，这里发现3306已经被占用，因此防止这种情况发生，可以避免使用3306mysql默认端口
# set mysql install base dir
basedir=/usr/local/mysql
# set the data store dir
datadir=/usr/local/mysql/data
# set the number of allow max connnection
max_connections=200
# set server charactre default encoding
character-set-server=utf8
# the storage engine
default-storage-engine=INNODB
lower_case_table_names=1
max_allowed_packet=16M
explicit_defaults_for_timestamp=true
user=mysql
basedir=/usr/local/mysql
#八、进入mysql文件夹，并安装mysql
# 进入mysql
# cd /usr/local/mysql
# 安装mysql
# bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/
2019-03-08 18:11:07 mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2019-03-08 18:11:24 The bootstrap log isn't empty:
2019-03-08 18:11:24 2019-03-08T10:11:07.208602Z 0 --bootstrap is deprecated. Please consider using --initialize instead设置文件及目录权限：
# cp ./support-files/mysql.server /etc/init.d/mysqld
# chown 777 my.cnf
# ls
binCOPYINGdatadocsincludelibmanmy.cnfREADMEsharesupport-files
# ls -l

# chmod +x /etc/init.d/mysqld
#
# mkdir data
#
# chown -R mysql:mysql data
#九、启动mysql
# 启动mysql
# /etc/init.d/mysqld restart
MySQL server PID file could not be found!
Starting MySQL.Logging to '/usr/local/mysql/data/CDH-141.err'.
..The server quit without updating PID file (/usr/local/mysql/data/CDH-141.pid).
#出现错误，解决方案如下：
#找到是否已经有进程占用
# ps aux|grep mysql

#十一、修改配置文件
# 进入/etc/profile文件夹
# vim /etc/profile
修改/etc/profile，在最后添加如下内容
# 修改/etc/profile文件
#set mysql environment
export PATH=$PATH:/usr/local/mysql/bin
# 使文件生效
# source /etc/profile十二、获得mysql初始密码
1）获得mysql初始密码
#cat /root/.mysql_secret
# Password set for user 'root@localhost' at 2019-03-08 17:40:42
poc3u0mO_luv
# 2）修改密码
# mysql -uroot -p
Enter password: #此处填写上边获取到的初始密码‘poc3u0mO_luv’
