CentOS 6.5 源码安装MySQL5.6.26

1：下载安装cmake （mysql5.5以后是通过cmake来编译的）

2：创建mysql的安装目录及数据库存放目录

#mkdir /usr/mysql                 //安装mysql

#mkdir /usr/mysql/data            //存放数据库

3：创建mysql用户及用户组

#groupadd mysql

#useradd -g mysql -s /bin/false -M mysql

4：安装mysql

tar -zxv -f /root/mysql-5.6.26.tar.gz

cd mysql-5.6.26

cmake -DCMAKE_INSTALL_PREFIX=/usr/mysql -DMYSQL_DATADIR=/usr/mysql/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1

---

centos7 需要执行

cmake -DCMAKE_INSTALL_PREFIX=/usr/mysql -DMYSQL_DATADIR=/usr/mysql/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost

---

 

如果报错则需要安装

yum -y install ncurses-devel

rm -f CMakeCache.txt

make

make install

5：配置MySQL

cd /usr/mysql

chown -R root:mysql .

chown -R mysql:mysql data

6：

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

7：初始化权限表

scripts/mysql_install_db --user=mysql --basedir=/usr/mysql --datadir=/usr/mysql/data

8：启动MySQL服务

cd /usr/mysql/support-files

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

chmod 755 /etc/init.d/mysqld

service mysqld start

---

 8. centos7 mysql5.7按照上述步骤完成安装后权限设置

sevice mysqld stop

cd /usr/mysql/bin

mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
mysql -u root mysql

update user set authentication_string=password('123456') where user='root';
FLUSH PRIVILEGES;
exit;

service mysql restart  #必须是重启服务器

mysql -uroot -p
Enter password: 123456

mysql>                 #出现此界面说明成功

mysql> SET PASSWORD = PASSWORD('1234567'); #再次登入之后需要重新修改默认密码

mysql> use mysql;

mysql>update user set host = '%' where user ='root';#修改任意IP可以访问
mysql>select host, user from user;
mysql>flush privileges;
