设置好/etc/yum.conf (需要设置代理的完成这里的设置)
proxy=http://IP:端口
proxy_username=XXXX
proxy_password=1987@qwe
开始安装:
[root@sample ~]# yum -y install mysql-server ← 安装MySQL
[root@sample ~]# yum -y install php-mysql ← 安装php-mysql
配置MySQL
[root@sample ~]#vim /etc/my.cnf ← 编辑MySQL的配置文件
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1 ← 找到这一行,在这一行的下面添加新的规则,让MySQL的默认编码为UTF-8
default-character-set = utf8 ← 添加这一行
然后在配置文件的文尾填加如下语句:
[mysql]
default-character-set = utf8
启动MySQL服务
[root@sample ~]# chkconfig mysqld on ← 设置MySQL服务随系统启动自启动
[root@sample ~]# chkconfig --list mysqld ← 确认MySQL自启动
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off ← 如果2--5为on的状态就OK
[root@sample ~]#/etc/rc.d/init.d/mysqld start ← 启动MySQL服务
Initializing MySQL database: [ OK ]
Starting MySQL: [ OK ]
MySQL初始环境设定
[1]为MySQL的root用户设置密码
MySQL在刚刚被安装的时候,它的root用户是没有被设置密码的。首先来设置MySQL的root密码。
[root@sample ~]# mysql -u root ← 用root用户登录MySQL服务器
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2 to server version: 4.1.20
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> select user,host,password from mysql.user; ← 查看用户信息
+------+------------------------------+---------------+
| user | host | password |
+------+------------------------------+---------------+
| root | localhost | | ← root密码为空
| root | sample.centospub.com | | ← root密码为空
| | sample.centospub.com | |
| | localhost | |
|root | % |XXX |
| | | |
+------+------------------------------+---------------+
4 rows in set (0.00 sec)
mysql> set password for root@localhost=password('在这里填入root密码'); ← 设置root密码
Query OK, 0 rows affected (0.01 sec)
mysql> set password for root@'sample.centospub.com'=password('在这里填入root密码'); ← 设置root密码
Query OK, 0 rows affected (0.01 sec)只有设置了这个才可以,才可以通过数据库来安装网址
mysql> set password for root@'xxx'=password('xxx'); ← 设置root密码
Query OK, 0 rows affected (0.01 sec)
mysql> select user,host,password from mysql.user; ← 查看用户信息
+------+--------------------------------+--------------------------+
| user | host | password |
+------+--------------------------------+--------------------------+
| root | localhost | 19b68057189b027f | ← root密码被设置
| root | sample.centospub.com | 19b68057189b027f | ← root密码被设置
| | sample.centospub.com | |
| | localhost | |
+------+--------------------------------+--------------------------+
4 rows in set (0.01 sec)
mysql> exit ← 退出MySQL服务器
Bye
然后,测试一下root密码有没有生效。
