Discuz! 7.2/Linux 环境搭建推
一、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:/var/lib/MySQL(可按情况设置)
Apache 网站根目录:/home/www/wwwroot(可按情况设置)
Apache 虚拟主机日志根目录:/home/www/logs(可按情况设置)
Apache 运行账户:www:www
二、系统环境部署及调整
1. 检查系统是否正常
# more /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.163.com(检查[[网络]]是否正常)
2. 关闭不需要的服务
# ntsysv
以下仅列出需要启动的服务,未列出的服务一律推荐关闭:
atd
crond
irqbalance
microcode_ctl
network
sendmail
sshd
syslog
3. 重新启动系统
# init 6
4. 配置 vim
# vi /root/.bashrc
在 alias mv='mv -i' 下面添加一行:alias vi='vim' 保存退出。
# echo 'syntax on' > /root/.vimrc
5. 使用 yum 程序安装所需开发包(以下为标准的 RPM 包名称)
# yum install ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel kernel
6. 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:
*/30 * * * * ntpdate 210.72.145.44
7. 源码编译安装所需包 (Source)
(1) GD2
# cd /usr/local/src # tar xzvf gd-2.0.34.tar.gz # cd gd-2.0.34 # ./configure --prefix=/usr/local/gd2 # make # make install
(2) LibXML2
# cd /usr/local/src # tar xjvf libxml2-2.6.30.tar.bz2 # cd libxml2-2.6.30 # ./configure --prefix=/usr/local/libxml2 # make # make install
(3) LibMcrypt
# cd /usr/local/src # tar xjvf 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 xzvf cronolog-1.7.0-beta.tar.gz # cd cronolog-1.7.0-beta # ./configure –prefix=/usr/local/cronolog # make # make install
8. 升级OpenSSL和OpenSSH
# cd /usr/local/src # tar xzvf openssl-0.9.8e.tar.gz # cd openssl-0.9.8e # ./config --prefix=/usr/local/openssl # make # make test # make install # cd .. # tar xzvf openssh-4.7p1.tar.gz # cd openssh-4.7p1 # ./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)禁止root直接登录
此处先建立一个普通系统用户:
# useradd username
# passwd username
找到:
#PermitRootLogin yes
改为:
PermitRootLogin no
(3)禁用服务器端GSSAPI
找到以下两行,并将它们注释:
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes
(4)禁用 DNS 名称解析
找到:
#UseDNS yes
改为:
UseDNS no
(5)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。
三、编译安装L.A.M.P环境
1. 下载软件
# cd /usr/local/src
httpd-2.2.6.tar.bz2
MySQL-5.0.45-linux-i686-glibc23.tar.gz
php-5.2.4.tar.bz2
ZendOptimizer-3.3.0-linux-glibc21-i386.tar.gz
2. 安装MySQL
# tar xzvf MySQL-5.0.45-linux-i686-glibc23.tar.gz # mv MySQL-5.0.45-linux-i686-glibc23 /usr/local/ # ln -s /usr/local/ MySQL-5.0.45-linux-i686-glibc23 /usr/local/MySQL # useradd MySQL # chown -R MySQL:root /usr/local/MySQL/ # cd /usr/local/MySQL # ./scripts/MySQL_install_db --user=MySQL # cp ./support-files/MySQL.server /etc/rc.d/init.d/MySQLd # chown root:root /etc/rc.d/init.d/MySQLd # chmod 755 /etc/rc.d/init.d/MySQLd # chkconfig --add MySQLd # chkconfig --level 3 5 MySQLd on # cp ./support-files/my-huge.cnf /etc/my.cnf # mv /usr/local/MySQL/data /var/lib/MySQL # chown -R MySQL:MySQL /var/lib/MySQL/ # vi /etc/my.cnf
修改以下内容:
(1) 在 [MySQL] 段增加一行:
default-character-set = GBK | latin1 | utf8 | BIG5
(2) 在 [MySQLd] 段增加或修改: datadir = /var/lib/MySQL --skip-innodb default-character-set = GBK | latin1 | utf8 | BIG5 --wait-timeout = 3 | 5 | 10 max_connections = 256 | 384 | 512 max_connect_errors = 10000000 thread_concurrency = CPU个数×2
将 log-bin 注释
# bin/MySQLadmin -u root password 'password_for_root'
3. 编译安装Apache
# cd /usr/local/src # tar xjvf httpd-2.2.6.tar.bz2 # cd httpd-2.2.6 # ./configure \ "--prefix=/usr/local/apache2" \ "--with-included-apr" \ "--enable-so" \ "--enable-deflate=shared" \ "--enable-expires=shared" \ "--enable-rewrite=shared" \ "--enable-static-support" \ "--disable-userdir" # make # make install # echo '/usr/local/apache2/bin/apachectl start ' >> /etc/rc.local
4. 编译安装PHP
# cd /usr/local/src # tar xjvf php-5.2.4.tar.bz2 # cd php-5.2.4 # ./configure \ "--prefix=/usr/local/php" \ "--with-apxs2=/usr/local/apache2/bin/apxs" \ "--with-config-file-path=/usr/local/php/etc" \ "--with-MySQL=/usr/local/MySQL" \ "--with-libxml-dir=/usr/local/libxml2" \ "--with-gd=/usr/local/gd2" \ "--with-jpeg-dir" \ "--with-png-dir" \ "--with-bz2" \ "--with-freetype-dir" \ "--with-iconv-dir" \ "--with-zlib-dir " \ "--with-openssl=/usr/local/openssl" \ "--with-mcrypt=/usr/local/libmcrypt" \ "--enable-soap" \ "--enable-gd-native-ttf" \ "--enable-ftp" \ "--enable-mbstring" \ "--enable-exif" \ "--disable-ipv6" \ "--disable-cgi" \ "--disable-cli" # make # make install # mkdir /usr/local/php/etc # cp php.ini-dist /usr/local/php/etc/php.ini
5. 安装Zend Optimizer
# cd /usr/local/src # tar xzvf ZendOptimizer-3.3.0-linux-glibc21-i386.tar.gz # ./ZendOptimizer-3.3.0-linux-glibc21-i386/install.sh
安装Zend Optimizer过程的最后不要选择重启Apache。
6. 整合Apache与PHP
# vi /usr/local/apache2/conf/httpd.conf
找到:
AddType application/x-gzip .gz .tgz
在该行下面添加
AddType application/x-httpd-php .php
找到: DirectoryIndex index.html
将该行改为 DirectoryIndex index.html index.htm index.php
找到:
#Include conf/extra/httpd-mpm.conf #Include conf/extra/httpd-info.conf #Include conf/extra/httpd-vhosts.conf #Include conf/extra/httpd-default.conf
去掉前面的“#”号,取消注释。
注意:以上 4 个扩展配置文件中的设置请按照相关原则进行合理配置!
修改完成后保存退出。
# /usr/local/apache2/bin/apachectl restart
7. 查看确认L.A.M.P环境信息、提升 PHP 安全性
在网站根目录放置 phpinfo.php 脚本,检查phpinfo中的各项信息是否正确。
确认 PHP 能够正常工作后,在 php.ini 中进行设置提升 PHP 安全性。
# vi /etc/php.ini
找到:
disable_functions =
设置为:
phpinfo,passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,pfsockopen,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server
四、服务器安全性设置
1. 设置系统防火墙
# vi /usr/local/sbin/fw.sh
将以下脚本命令粘贴到 fw.sh 文件中。
#!/bin/bash # Stop iptables service first service iptables stop # Load FTP Kernel modules /sbin/modprobe ip_conntrack_ftp /sbin/modprobe ip_nat_ftp # Inital chains default policy /sbin/iptables -F -t filter /sbin/iptables -P INPUT DROP /sbin/iptables -P OUTPUT ACCEPT # Enable Native Network Transfer /sbin/iptables -A INPUT -i lo -j ACCEPT # Accept Established Connections /sbin/iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # ICMP Control /sbin/iptables -A INPUT -p icmp -m limit --limit 1/s --limit-burst 10 -j ACCEPT # WWW Service /sbin/iptables -A INPUT -p tcp --dport 80 -j ACCEPT # FTP Service /sbin/iptables -A INPUT -p tcp --dport 21 -j ACCEPT # SSH Service /sbin/iptables -A INPUT -p tcp --dport 22 -j ACCEPT
# chmod 755 /usr/local/sbin/fw.sh # echo '/usr/local/sbin/fw.sh' >> /etc/rc.local # /usr/local/sbin/fw.sh
