1.解压mysql

tar -xf mysql-5.6.30-linux-glibc2.5-x86_64.tar.gz  -C /usr/local

mv mysql-5.6.30-linux-glibc2.5-x86_64 mysql-5.6.30

 

2.添加用户与组

groupadd mysql

useradd -g mysql mysql  -s /sbin/nologin 

chown -R mysql:mysql mysql-5.6.30

 

3.安装数据库

mkdir /usr/local/mysql-5.6.30/data3306

cd mysql-5.6.21/scripts

./mysql_install_db  --user=mysql --basedir=/usr/local/mysql-5.6.30/ --datadir=/usr/local/mysql-5.6.30/data3306/

 

4.配置文件

cd /usr/local/mysql-5.6.30/support-files

cp my-default.cnf /etc/my.cnf

cp mysql.server /etc/init.d/mysql

vim /etc/init.d/mysql

修改文件中的两个变更值

[mysqld]

port        = 3306

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

max-connections = 800

key_buffer_size = 384M

max_allowed_packet = 1073M

table_open_cache = 512

sort_buffer_size = 512K

innodb_data_home_dir = /usr/local/mysql-5.6.30/data3306

innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend

innodb_log_group_home_dir = /usr/local/mysql-5.6.30/data3306

innodb_buffer_pool_size = 5972M

innodb_additional_mem_pool_size = 10M

innodb_flush_method = O_DIRECT

innodb_file_per_table = 1

5.配置环境变量

vi /etc/profile

export MYSQL_HOME="/usr/local/mysql-5.6.30"

export PATH="$PATH:$MYSQL_HOME/bin"

 

6.添加自启动服务

chkconfig mysql on

 

7.启动mysql

service mysql start

 

8.登录mysql及改密码

mysqladmin -u root password 'your_password'     #修改root用户密码

mysql -u root -p     #登录mysql,需要输入密码
