centos7 使用二进制安装mysql 5.7.23

1、下载二进制安装包 mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz

cd /usr/local/src

wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz

2、解压，创建用户

[root@8d83e8f22faa src]# tar -xzvf mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz

[root@8d83e8f22faa src]# ll

total 629300

drwxr-xr-x. 9 root root 129 Sep 4 13:41 mysql-5.7.23-linux-glibc2.12-x86_64

-rw-r--r--. 1 root root 644399365 Sep 4 13:38 mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz

[root@8d83e8f22faa src]# mv mysql-5.7.23-linux-glibc2.12-x86_64 /usr/local/mysql

[root@8d83e8f22faa src]# cd /usr/local/mysql/

[root@8d83e8f22faa mysql]# ll

total 36

drwxr-xr-x. 28 root root 4096 Sep 4 13:41 share

drwxr-xr-x. 2 root root 90 Sep 4 13:41 support-files

[root@8d83e8f22faa mysql]# groupadd mysql //创建用户组mysql

[root@8d83e8f22faa mysql]# useradd -r -g mysql mysql //-r参数表示mysql用户是系统用户，不可用于登录系统，创建用户mysql并将其添加到用户组mysql中

[root@8d83e8f22faa mysql]# chown -R mysql ../mysql/

[root@8d83e8f22faa mysql]# chgrp -R mysql ../mysql/

3、创建配置文件

cat > /etc/my.cnf << EOF

[client]

port = 3306

socket = /var/lib/mysql/mysql.sock

[mysqld]

character_set_server=utf8

init_connect='SET NAMES utf8'

basedir=/usr/local/mysql

datadir=/usr/local/mysql/data

socket=/var/lib/mysql/mysql.sock

log-error=/var/log/mysql/mysqld.log

#pid-file=/var/run/mysqld/mysqld.pid --会有问题

pid-file=/usr/local/mysql/data/mysqld.pid

lower_case_table_names = 1 #不区分大小写

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

max_connections=5000

default-time_zone = '+8:00'

EOF

4、初始化数据库

[root@8d83e8f22faa mysql]# yum install libaio numactl

[root@8d83e8f22faa log]# touch mysqld.log

[root@8d83e8f22faa log]# chown -R mysql:mysql mysqld.log

[root@8d83e8f22faa log]# vi /root/.bash_profile #增加mysql的bin目录

PATH=/usr/local/mysql/bin:/data/mysql/lib:$PATH

export PATH

[root@8d83e8f22faa log]#

[root@8d83e8f22faa log]# source /root/.bash_profile

[root@8d83e8f22faa log]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --lc_messages_dir=/usr/local/mysql/share --lc_messagges=en_US

5、查看初始密码

[root@8d83e8f22faa log]# cat mysqld.log

[root@8d83e8f22faa log]# mysql -uroot -p

Enter password:

[root@8d83e8f22faa log]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

[root@8d83e8f22faa log]#

[root@8d83e8f22faa log]# chkconfig --add mysqld

[root@8d83e8f22faa log]# chkconfig --list
