1.首先关闭linux的防火墙,查看linux防火墙博客 https://www.cnblogs.com/liuyi-clover/p/9755966.html
2.将下载好的mysql压缩文件放置在linux的/usr/local文件夹下,解压该压缩文件
tar -zxvf mysql-5.6.44-linux-glibc2.12-x86_64.tar.gz
3.将解压后的文件重命名为mysql
mv mysql-5.6.44-linux-glibc2.12-x86_64 mysql
4.创建mysql用户组及用户
groupadd mysql
useradd -r -g mysql mysql
5、进入到mysql目录,执行添加MySQL配置的操作
cd mysql
cp support-files/my-default.cnf /etc/my.cnf
是否覆盖?按y 回车
6、编辑/etc/my.cnf文件
可用工具下载文件到桌面,修改后再上传到服务器替换
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # These are commonly set, remove the # and set as required. basedir = /usr/local/mysql datadir = /usr/local/mysql/data port = 3306 # server_id = ..... socket = /tmp/mysql.sock character-set-server = utf8 skip-name-resolve log-err = /usr/local/mysql/data/error.log pid-file = /usr/local/mysql/data/mysql.pid # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
7.在mysql当前目录下设定目录的访问权限(注意后面的小点,表示当前目录)
cd /usr/local/mysql
chown -R mysql .
chgrp -R mysql .
scripts/mysql_install_db --user=mysql
chown -R root .
chown -R mysql data
8、初始化数据(在mysql/bin或者mysql/scripts下有个 mysql_install_db 可执行文件初始化数据库),进入该目录下,执行下面命令
cd /usr/local/mysql/scripts
安装autoconf库
yum -y install autoconf
初始化mysql
./mysql_install_db --verbose --user=root --defaults-file=/etc/my.cnf --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql --pid-file=/usr/local/mysql/data/mysql.pid --tmpdir=/tmp
9、启动mysql,进入/usr/local/mysql/bin目录,执行下面命令
cd /usr/local/mysql/bin
./mysqld_safe --defaults-file=/etc/my.cnf --socket=/tmp/mysql.sock --user=root &
注意,如果光标停留在屏幕上,表示启动成功,需要我们先关闭Xshell终端,再重新打开软件
10、设置开机启动,新开启shell中断后,进入mysql目录,执行下面命令
cd /usr/local/mysql
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql
chmod 700 /etc/init.d/mysql
chkconfig --add mysqld
chkconfig --level 2345 mysqld on
chown mysql:mysql -R /usr/local/mysql/
11.重启linux,查看mysql状态
reboot(可在控制台手动重启)
service mysqld status
mysql若没启动,则启动mysql
service mysql start
12、添加远程访问权限
添加mysql命令
ln -s /usr/local/mysql/bin/mysql /usr/bin (mysql的安装路径)
登录mysql,执行下面命令
mysql -u root -h 127.0.0.1 -P3306 -p (直接回车,可无密码登陆)
13.修改密码,执行下面命令
mysql> select host,user,password from mysql.user;
mysql> update mysql.user set password=password('12345') where user='root';
mysql> flush privileges;
mysql> quit
14.重新启动mysql,就可以使用 新密码登录了
service mysqld status
mysql若没启动,则启动mysql
service mysql start
mysql -u root -h 127.0.0.1 -P3306 -p
输入密码:12345
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '12345' WITH GRANT OPTION;
mysql> flush privileges;
15、连接Navicat
