二、Mysql的配置
1、在安装完mysql数据库以后，会发现会多出一个mysqld的服务，这个就是数据库服务，输入 service mysqld start 命令就可以启动的mysql服务。
[root@iZbp19m6s0kz1ktg5okuauZ ~] # service mysqld start
初始化 MySQL 数据库： WARNING: The host 'xiaoluo' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !
Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h xiaoluo password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script![确定]
正在启动 mysqld： [确定]
2、第一次启动mysql服务器以后会提示非常多的信息，目的就是对mysql数据库进行初始化操作，重新启动mysql服务，就不会提示这么多信息了，如：
[root@iZbp19m6s0kz1ktg5okuauZ ~]# service mysqld start
停止 mysqld： [确定]
正在启动 mysqld： [确定]
3、在使用mysql数据库时，首先启动mysqld服务，可以使用chkconfig --list | grep mysqld 命令查看mysql服务是不是开机自动启动
[root@iZbp19m6s0kz1ktg5okuauZ ~]# chkconfig --list | grep mysqld
mysqld 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭
4、如果mysqld服务并没有开机自动启动，可以使用 chkconfig mysqld on 命令来将其设置成开机启动
[root@iZbp19m6s0kz1ktg5okuauZ ~]# chkconfig mysqld on
[root@iZbp19m6s0kz1ktg5okuauZ ~]# chkconfig --list | grep mysqld
mysqld 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭
5、mysql数据库安装以后只会有一个root管理员账号，此时root账号没有设置密码，在第一次启动mysql服务时，会进行数据库的一些初始化工作，会输出信息
/usr/bin/mysqladmin -u root password 'new-password' // 为root账号设置密码
6、使用mysqladmin -u root password命令给root账号设置密码
[root@iZbp19m6s0kz1ktg5okuauZ ~]# mysqladmin -u root password
'root'
mysql的主配置文件是/etc/my.cnf /var/lib/mysql mysql数据库的数据库文件存放位置
[root@iZbp19m6s0kz1ktg5okuauZ ~]# ls my.cnf
my.cnf
[root@iZbp19m6s0kz1ktg5okuauZ ~]# cat my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
/var/lib/mysql mysql数据库的数据库文件存放位置
[root@iZbp19m6s0kz1ktg5okuauZ ~ ]# cd /var/lib/mysql/
[root@iZbp19m6s0kz1ktg5okuauZ mysql ]# ls -l

Mysql的优化
mysql的优化分为两方面：
-
服务器使用前的优化
-
服务使用中的优化
优化数据库对象
1、 根据需求选择正确的存储引擎，比如MySAM、InnoDB
2、 默认值尽可能的使用 NOT NULL
3、尽量少的使用VARCHAR，TEXT，BLOB这三个字段，效率，char>varchar>text
4、优化索引
普通索引、唯一索引、主索引、外键索引、复合索引
5、表的设计符合3NF
优化SQL
show status命令提高sql的执行频率
show status like 'Com_%';
建立合适的索引
使用show status like 'Handler_%'命令查看索引的使用情况
show status like 'Handler_%';
"test_table"为测试表
analyze table test_table;
check table test_table;
设置权限
mysql -r /var/lib/mysql
允许 root远程登录
grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
flush privileges;
优化mysql数据库性能参数
(1)、max_connections：
(2)、record_buffer：
(3)、key_buffer_size：
(4)、back_log：
(5)、interactive_timeout：
(6)、sort_buffer：
(7)、table_cache：
(8)、thread_cache_size：
