大纲: 一、系统安装 二、编译安装基本环境 三、配置虚拟主机及基本性能调优 四、基本安全设置 五、附录及相关介绍
一、系统安装 1. 分区 /boot 100M左右 SWAP 物理内存的2倍(如果你的物理内存大于4G以上,分配4G即可) / 15G /usr/local 20G (用于安装软件) /data 剩余所有空间
2. 系统初始化脚本(根据具体需求关闭不需要的服务)- #vi init.sh
- -------------------cut begin-------------------------------------------
- #welcome
- cat << EOF
- +--------------------------------------------------------------+
- | === Welcome to Centos System init === |
- +--------------http://www.linuxtone.org------------------------+
- +----------------------Author:NetSeek--------------------------+
- EOF
- #disable ipv6
- cat << EOF
- +--------------------------------------------------------------+
- | === Welcome to Disable IPV6 === |
- +--------------------------------------------------------------+
- EOF
- echo "alias net-pf-10 off" >> /etc/modprobe.conf
- echo "alias ipv6 off" >> /etc/modprobe.conf
- /sbin/chkconfig --level 35 ip6tables off
- echo "ipv6 is disabled!"
- #disable selinux
- sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config
- echo "selinux is disabled,you must reboot!"
- #vim
- sed -i "8 s/^/alias vi='vim'/" /root/.bashrc
- echo 'syntax on' > /root/.vimrc
- #zh_cn
- sed -i -e 's/^LANG=.*/LANG="zh_CN.GB18030"/' /etc/sysconfig/i18n
- #tunoff services
- #--------------------------------------------------------------------------------
- cat << EOF
- +--------------------------------------------------------------+
- | === Welcome to Tunoff services === |
- +--------------------------------------------------------------+
- EOF
- #---------------------------------------------------------------------------------
- for i in `ls /etc/rc3.d/S*`
- do
- CURSRV=`echo $i|cut -c 15-`
- echo $CURSRV
- case $CURSRV in
- crond | irqbalance | microcode_ctl | network | random | sendmail | sshd | syslog | local | mysqld )
- echo "Base services, Skip!"
- ;;
- *)
- echo "change $CURSRV to off"
- chkconfig --level 235 $CURSRV off
- service $CURSRV stop
- ;;
- esac
- done
- -------------------cut end-------------------------------------------
- #sh init.sh (执行上面保存的脚本,仍后重启)
复制代码 二、编译安装基本环境
1. 安装准备 1) 系统约定 软件源代码包存放位置 /usr/local/src 源码包编译安装位置(prefix) /usr/local/software_name 脚本以及维护程序存放位置 /usr/local/sbin MySQL 数据库位置 /data/mysql/data(可按情况设置) Apache 网站根目录 /data/www/wwwroot(可按情况设置) Apache 虚拟主机日志根目录 /data/www/logs(可按情况设置) Apache 运行账户 www:www (useradd -d /data/www/;chown www.www /data/www/wwwroot)
2) 系统环境部署及调整 检查系统是否正常 # tail -n100 /var/log/messages (检查有无系统级错误信息) # dmesg (检查硬件设备是否有错误信息) # ifconfig(检查网卡设置是否正确) # ping www.linuxtone.org (检查网络是否正常)
3) 使用 yum 程序安装所需开发包(以下为标准的 RPM 包名称) #rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #yum install ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel \ ncurses-devel zlib-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel libXpm-devel \ gettext-devel pam-devel kernel
4) 定时校正服务器时钟,定时与中国国家授时中心授时服务器同步 # crontab -e 加入一行: 15 3 * * * /usr/sbin/ntpdate 210.72.145.44 > /dev/null 2>&1
2. 编译安装软件包 源码编译安装所需包(Source) 1) GD2 # cd /usr/local/src # tar xvf gd-2.0.35.tar.gz # cd gd-2.0.35 # ./configure --prefix=/usr/local/gd2 # make # make install
2) LibXML2 # cd /usr/local/src # tar xvf libxml2-2.6.29.tar.bz2 # cd libxml2-2.6.29 # ./configure --prefix=/usr/local/libxml2 # make # make install
3) LibMcrypt # cd /usr/local/src # tar xvf libmcrypt-2.5.8.tar.bz2 # cd libmcrypt-2.5.8 # ./configure --prefix=/usr/local/libmcrypt # make # make install
4) Apache日志截断程序 # cd /usr/local/src # tar xvf cronolog-1.6.2.tar.gz # cd cronolog-1.6.2 # ./configure --prefix=/usr/local/cronolog # make # make install
3. 升级OpenSSL和OpenSSH # cd /usr/local/src # tar xvf openssl-0.9.8g.tar.gz # cd openssl-0.9.8g # ./config --prefix=/usr/local/openssl # make # make test # make install # cd .. # tar xvf openssh-5.0p1.tar.gz # cd openssh-5.0p1 # ./configure \ "--prefix=/usr" \ "--with-pam" \ "--with-zlib" \ "--sysconfdir=/etc/ssh" \ "--with-ssl-dir=/usr/local/openssl" \ "--with-md5-passwords" # make # make install 1) 禁用 SSH V1 协议 找到#Protocol 2,1改为:Protocol 2
2) 禁用服务器端GSSAPI 找到以下两行,并将它们注释: GSSAPIAuthentication yes GSSAPICleanupCredentials yes
3) 禁用 DNS 名称解析 找到:#UseDNS yeas改为:UseDNS no
4)禁用客户端 GSSAPI # vi /etc/ssh/ssh_config 找到:GSSAPIAuthentication yes 将这行注释掉。 最后,确认修改正确后重新启动 SSH 服务 # service sshd restart # ssh -v 确认 OpenSSH 以及 OpenSSL 版本正确。
以上SSH配置可利用以下脚本自动修改:- -------------------cut begin-------------------------------------------
- #init_ssh
- ssh_cf="/etc/ssh/sshd_config"
- sed -i -e '74 s/^/#/' -i -e '76 s/^/#/' $ssh_cf
- sed -i "s/#UseDNS yes/UseDNS no/" $ssh_cf
- #client
- sed -i -e '44 s/^/#/' -i -e '48 s/^/#/' $ssh_cf
- echo "ssh is init is ok.............."
- -------------------cut end---------------------------------------------
