centos 6 mysql 5.6 源码安装

1. 安装必要的组件

yum install –y autoconf automake imake libxml2-devel
 expat-devel cmake gcc gcc-c++ libaio libaio-devel bzr bison libtool ncurses5-devel

2. 下载解压mysql软件

# cd /usr/local/src
# wget -c http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz/from/http://cdn.mysql.com/ -O mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz
# tar zxvf mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz –C ../
# cd /usr/local/
# ln -s mysql-5.6.14-linux-glibc2.5-x86_64 mysql

3. 创建Mysql用户组和用户，及数据库存放目录：

# mkdir -p /data/mysql_data_3306
# mkdir -p /data/mysql_log
# mkdir -p /data/log-bin
# groupadd mysql
# useradd mysql -g mysql -M -s /sbin/nologin
# chown -R mysql.mysql /data/mysql_data_3306 /data/mysql_log /data/log-bin
# chown -R mysql.mysql /usr/local/mysql-5.6.14-linux-glibc2.5-x86_64

4. 配置文件（依具体环境）

# vim /etc/my.cnf

[mysqld]
# GENERAL #
user = mysql
default-storage-engine = InnoDB
socket = /data/mysql_data_3306/mysql.sock
pid-file = /data/mysql_data_3306/mysql.pid
port = 3306
# MyISAM #
key_buffer_size = 1344M
myisam_recover = FORCE,BACKUP

slow-query-log = 1
long_query_time = 1
slow-query-log-file = /data/mysql_log/mysql-slow-3306.log
# FOR SLAVE #
#binlog-format = ROW
#log-slave-updates = true
#gtid-mode = on

　5. 系统服务

# cp -af /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld_3306
# vi /etc/init.d/mysqld_3306
修改两处位置：
basedir=/usr/local/mysql
datadir=/data/mysql_data_3306
 
执行如下命令
# chmod 755 /etc/init.d/mysqld_3306
# chkconfig --add mysqld_3306
# chkconfig --level 345 mysqld_3306 on

　

6. 初始化数据库

# cd /usr/local/mysql
# ./scripts/mysql_install_db --user=mysql --defaults-file=/etc/my.cnf

　　

7. 启动数据库进程

# service mysqld_3306 start

　

8. 创建sock软连接

ln -s /data/mysql_data_3306/mysql.sock /tmp/mysql.sock

　　

9. 修改root密码

# /usr/local/mysql/bin/mysql -p -uroot -S /tmp/mysql.sock #这里直接回车就能进入数据库系统
Mysql> delete from mysql.user where user='';
Mysql> update mysql.user set password=PASSWORD(‘xxxxxxxx’) where user='root';
Mysql>flush privileges;
