CentOS 7.5安装MySQL5.7.23

注：安装问题请参考文章最后！

1.服务器版本

# lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
Description:    CentOS Linux release 7.5.1804 (Core)
Release:    7.5.1804
Codename:   Core

2.下载MySQL

# cd /home/install-files
# wget http://ftp.kaist.ac.kr/mysql/Downloads/MySQL-5.7/mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz

3.解压修改安装名称

# tar zxvf mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
# cd /usr/local/
# ls
aegis  bin  etc  games  include  lib  lib64  libexec  mysql-5.7.23-linux-glibc2.12-x86_64  sbin  share  src
# mv mysql-5.7.23-linux-glibc2.12-x86_64/ mysql
# ls
aegis  bin  etc  games  include  lib  lib64  libexec  mysql  sbin  share  src

4.创建目录

# mkdir -p /mysql/data
# mkdir -p /mysql/sock
# mkdir -p /mysql/log
# mkdir -p /mysql/pid

5.创建组和用户

# groupadd mysql
# useradd mysql -g mysql -d /usr/local/mysql -s /sbin/nologin

6.安装

# /usr/local/mysql
# ls
COPYING  README  bin  docs  include  lib  man  share  support-files

6.1.配置文件

注：第一次，请注释“bind-address”，需要root本地登录，初始化mysql用户

[mysqld]
user=mysql
bind-address=192.168.80.168
port=3306
basedir=/usr/local/mysql
datadir=/mysql/data
socket=/mysql/sock/mysql.sock
pid-file=/mysql/pid/mysql.pid
log-error=/mysql/log/mysql-error.log

symbolic-links=0
default-storage-engine=INNODB
character_set_server=utf8
collation-server=utf8_general_ci
transaction_isolation=REPEATABLE-READ
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[mysql]
default-character-set=utf8
port=3306
socket=/mysql/sock/mysql.sock

注:禁用ssl mode，在[mysqld]下配置（独占一行）: skip_ssl

6.2.启动服务文件

# cd /usr/local/mysql/support-files/
# cp mysql.server /etc/init.d/mysql

注：修改启动文件：

# vim /etc/init.d/mysql
basedir=/usr/local/mysql
datadir=/mysql/data

6.3.更改涉及拥有者

# chown -R mysql:mysql /mysql
# chown -R mysql:mysql /etc/my.cnf
# chown -R mysql:mysql /usr/local/mysql

6.4.初始化 mysql 的数据库

注：mysq默认root本地登录密码: avi>2Wlg%Khz

# /usr/local/mysql/bin

6.6.启动mysql数据库

# chown -R mysql:mysql /mysql
# chown -R mysql:mysql /etc/my.cnf
# chown -R mysql:mysql /usr/local/mysql
# service mysql start
Starting MySQL.                                            [  OK  ]

# ps -ef |grep mysql
root      2320     1  0 12:10 pts/0    00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/mysql/data --pid-file=/mysql/pid/mysql.pid
mysql     2583  2320  1 12:10 pts/0    00:00:00 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/mysql/log/mysql-error.log --pid-file=/mysql/pid/mysql.pid --socket=/mysql/sock/mysql.sock --port=3306
root      2632  1016  0 12:11 pts/0    00:00:00 grep --color=auto mysql

6.7.本地root用户登录mysql，初始化远程登录用户

# ./mysql -uroot -p
Enter password:

7.设置mysql服务开机自启动

# chkconfig --add mysql
# chkconfig mysql on
# chkconfig --list | grep mysql

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off

8.配置mysql环境变量

# vim /etc/profile

注：最后添加

export MYSQL_HOME=/usr/local/mysql
export PATH=$MYSQL_HOME/bin:$PATH

注：生效环境变量

# source /etc/profile

9.测试mysql安装所有的安装成功？

# mysql --version

# mysql -h 192.168.80.168  -uidba -p

1.检查：配置文件没有问题
2.检查：所有涉及文件已归属mysql用户没问题
3.检查：数据库“bind-address”没闻到
4.清空“/mysql/data”下编译的所有，即数据库文件，重新执行：
./mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/data

-bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory
