2、安装步骤
解压：
groupadd mysql useradd -r -g mysql -s /bin/false mysql cd /usr/local tar zxvf /path/to/mysql-VERSION-OS.tar.gz mv full-path-to-mysql-VERSION-OS mysql chown -R mysql mysql/ chgrp -R mysql mysql/ cd mysql mkdir mysql-files chown mysql:mysql mysql-files chmod 750 mysql-files
创建配置文件：
#先安装一下这个，要不然初始化有可能会报错
yum install libaio
my.cnf配置：
#创建配置文件，内容如下，可以添加你需要的配置：
vim /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
[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
#
# 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

初始化数据库：
mkdir /data/log chown -R mysql:mysql /data cd /var/run/ mkdir mysqld chmod 777 mysqld cd mysqld vim mysqld.pid chmod 777 mysqld.pid chown mysql:mysql mysqld.pid /usr/local/mysql/bin/mysqld --initialize --user=mysql
查看初始密码：
cat /data/log/mysqld.log
#执行后关注最后一点：root@localhost: 这里就是初始密码
启动服务，进入mysql，修改初始密码，运行远程连接（这里执行完后，密码将变成：123456）
/usr/local/mysql/support-files/mysql.server start #vim /etc/mysql/my.cnf #在[mysqld]项下添加 #skip-grant-tables #service mysqld restart cd /usr/local/mysql/bin ./mysql -uroot -p 执行后输入初始密码 alter user 'root'@'localhost' identified by '123456'; flush privileges; use mysql; #设置远程登录 GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; flush privileges;
开机自启：
cd /usr/local/mysql/ cp support-files/mysql.server /etc/init.d/mysqld chkconfig --add mysqld 8、使用service mysqld命令启动/停止服务 service mysqld start/stop/restart
防火墙开开放3309端口：
vim /etc/sysconfig/iptables
service iptables restart
service mysqld restart
配置全局环境变量：
vi /etc/profile PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH export PATH 设置环境变量立即生效 # source /etc/profile
查看安装路径：
find / -name mysql
