本机版本:
安装MysqL5.7.16:
1、火狐浏览器访问官网http://dev.MysqL.com/downloads/MysqL/,点击downloads然后点击MysqL Community Server,切换Linux- generic
2、点击download按钮跳转按钮,按F12,点击网络,然后点击No thanks,just start my download,在网络那里查看请求的url
3、复制请求的url,在服务器上输入
wget http://dev.MysqL.com/get/Downloads/MysqL-5.7/MysqL-5.7.16-linux-glibc2.5-x86_64.tar.gz
tar -zxvf MysqL-5.7.16-linux-glibc2.5-x86_64.tar.gz解压后输入:ll命令查看:
mv MysqL-5.7.16-linux-glibc2.5-x86_64 /usr/local/MysqL
5、添加系统MysqL组和MysqL用户以及修改目录的权限:
groupadd MysqL useradd -r -g MysqL MysqL cd /usr/local chown -R MysqL MysqL/ chgrp -R MysqL MysqL/ mkdir /usr/local/MysqL/data /usr/local/MysqL/log
6、创建cnf文件
vim /etc/my.cnf清除内容,复制粘贴以下内容,然后按esc输入:wq进行保存退出
[client] port = 3306 socket = /tmp/MysqL.sock [MysqLd] server_id=10 port = 3306 user = MysqL socket = /tmp/MysqL.sock basedir = /usr/local/MysqL datadir = /usr/local/MysqL/data pid-file = /usr/local/MysqL/data/MysqL.pid max_connections = 1000 max_connect_errors = 1000 table_open_cache = 1024 max_allowed_packet = 128M open_files_limit = 65535 #####====================================[innodb]============================== innodb_buffer_pool_size = 1024M innodb_file_per_table = 1 innodb_write_io_threads = 4 innodb_read_io_threads = 4 innodb_purge_threads = 2 innodb_flush_log_at_trx_commit = 1 innodb_log_file_size = 512M innodb_log_files_in_group = 2 innodb_log_buffer_size = 16M innodb_max_dirty_pages_pct = 80 innodb_lock_wait_timeout = 30 innodb_data_file_path=ibdata1:1024M:autoextend #####====================================[log]============================== log_error = /usr/local/MysqL/log/MysqL-error.log slow_query_log = 1 long_query_time = 1 slow_query_log_file = /usr/local/MysqL/log/MysqL-slow.log sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
7、安装数据库
cd MysqL/ bin/MysqLd --initialize --user=MysqL --basedir=/usr/local/MysqL --datadir=/usr/local/MysqL/data --innodb_undo_tablespaces=3 --explicit_defaults_for_timestamp
cp support-files/MysqL.server /etc/init.d/MysqL /etc/init.d/MysqLd restart
vi /etc/profile
添加行:MysqL_HOME=/usr/local/MysqL
PATH添加::$MysqL_HOME/bin
export添加:MysqL_HOME
然后按esc输入:wq进行保存退出
10、进入MysqL与修改密码
查看初始密码
cat /root/.MysqL_secret
登录
bin/MysqL -uroot -p输入cat查看的密码
修改密码
update MysqL.user set authentication_string=password('root') where user='root'; SET PASSWORD=PASSWORD('root');
use MysqL GRANT ALL PRIVILEGES ON *.* TO 'test'@'%' IDENTIFIED BY 'test' WITH GRANT OPTION; flush privileges;
CREATE DATABASE `zp` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
GRANT ALL ON zp.* TO zp@'%' IDENTIFIED BY '123456';
13、防火墙开放相关端口
firewall-cmd --add-port=3306/tcp --permanent firewall-cmd --query-port=3306/tcp
如果query的命令执行结果为no,则把add命令的--permanent去掉(这个permanent选项是指永久打开端口,即重启机器也会自动打开端口,去掉后重启机器不会自动打开端口)
如果防火墙没有启动则会提示FirewallD is not running,启动防火墙命令:
systemctl start firewalld
14、连接工具测试是否成功连接数据库
本人使用Navicat Premium测试,输入ip地址和端口,用户和密码
