配置服务器CentOS

root帐号登录服务器

查看版本
cat /etc/issue
#CentOS release 5.2 (Final)
调整时区时间
sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
sudo /usr/sbin/ntpdate us.pool.ntp.org
很简单吧,解析一下,第一句是把当前时区调整为上海就是+8区,想改其他时区也可以去看看/usr/share/zoneinfo目录;然后第二句 是利用ntpdate同步标准时间.
没有ntpdate的可以yum一下: yum install -y ntpdate

新建用户

#test
su app
sudo ls -all

配置自动登录
su app
cd /home/app/
mkdir .ssh
touch .ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

#回到本地机器

MySQL

version 5.1.37:

cd
cd src
wget http://mirrors.dedipower.com/www.mysql.com/Downloads/MySQL-5.1/mysql-5.1.43.tar.gz
tar xzf mysql-5.1.43.tar.gz
cd mysql-5.1.43
./configure --prefix=/usr/local/mysql --with-plugins=innobase
make
sudo make install

sudo cp support-files/my-medium.cnf /etc/my.cnf
cd /usr/local/mysql
sudo bin/mysql_install_db --user=mysql

sudo chown -R root /usr/local/mysql
sudo chown -R mysql /usr/local/mysql/var
sudo chgrp -R mysql /usr/local/mysql

sudo /usr/local/mysql/bin/mysqld_safe --user=mysql &

cd /usr/bin
sudo ln -s /usr/local/mysql/bin/mysql

#等待几秒
/usr/bin/mysqladmin -u root password 'new-password'

#test
cd /usr/local/mysql/mysql-test ;sudo perl mysql-test-run.pl


------
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/local/mysql/bin/mysqladmin -u root password 'new-password'
/usr/local/mysql/bin/mysqladmin -u root -h alimonitor3.alimonitor.com password 'new-password'

Alternatively you can run:
/usr/local/mysql/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/local/mysql ; /usr/local/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/local/mysql/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/local/mysql/bin/mysqlbug script!

To Temporarily disable enforcement on a running system

To permanently disable enforcement during a system startup
change "enforcing" to "disabled" in ''/etc/selinux/config'' and reboot.
.
By default, CentOS 5 has the SE Linux feature set to "enforcing". We are looking into ways to removing these steps.
