L.A.M.P环境配置文档--CentOS
L.A.M.P 环境部署详细步骤本文所用的操作系统为 CentOS 3.8，如果使用 Red Hat AS3/4 则不能使用 yum RPM 包管理命令！
推荐使用 CentOS 3.8 系统。
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
Apache 网站根目录
/data/wwwroot
Apache 虚拟主机日志根目录
/data/logs/www
Apache 运行账户
www:www
yum RPM包信息文件
/etc/yum.list
二、系统环境部署及调整
1. 检查系统是否正常
# more /var/log/messages （检查有无系统内核级错误信息）
# 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，未列出的服务一律关闭：
crond
irqbalance （仅当服务器CPU为S.M.P架构或支持双核心、HT技术时，才需开启，否则关闭。）
microcode_ctl
network
random
sendmail
sshd
syslog
3. 对TCP/IP网络参数进行调整，加强抗SYN Flood能力
# echo 'net.ipv4.tcp_syncookies = 1' >> /etc/sysctl.conf
# sysctl -p
4. 配置yum
# rpm --import /usr/share/doc/centos-release-3/RPM-GPG-KEY-CentOS-3
# yum list | tee /etc/yum.list
5. 修改命令history记录
# vi /etc/profile
找到 HISTSIZE=1000 改为 HISTSIZE=50
6. 定时校正服务器时间
# yum install ntp
# crontab -e
加入一行：
*/15 * * * * ntpdate 210.72.145.44
## 210.72.145.44 为中国国家授时中心服务器地址。
7. 重新启动系统
# init 6
8. 使用 yum 程序安装所需开发包（以下为标准的 RPM 包名称）
gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel zlib-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel
9. 源码编译安装所需包(Source)
(1) GD2
# cd /usr/local/src
# wget http://download.discuz.net/env/gd-2.0.33.tar.gz
# tar xzvf gd-2.0.33.tar.gz
# cd gd-2.0.33
# ./configure --prefix=/usr/local/gd2
# make
# make install
(2) LibXML2
# cd /usr/local/src
# wget http://download.discuz.net/env/libxml2-2.6.26.tar.bz2
# tar xjvf libxml2-2.6.26.tar.bz2
# cd libxml2-2.6.26
# ./configure --prefix=/usr/local/libxml2
# make
# make install
(3) Apache日志截断程序
# cd /usr/local/src
# wget http://download.discuz.net/env/cronolog-1.6.2.tar.gz
# tar xzvf cronolog-1.6.2.tar.gz
# cd cronolog-1.6.2
# ./configure –prefix=/usr/local/cronolog
# make
# make install
10. 升级OpenSSL和OpenSSH
# cd /usr/local/src
# wget http://download.discuz.net/env/openssl-0.9.7j.tar.gz
# wget http://download.discuz.net/env/openssh-4.2p1.tar.gz
# tar xzvf openssl-0.9.7j.tar.gz
# cd openssl-0.9.7j
# ./config --prefix=/usr/local/openssl
# make
# make test
# make install
# cd ..
# tar xzvf openssh-4.2p1.tar.gz
# cd openssh-4.2p1
# ./configure\
"--prefix=/usr" \
"--with-pam" \
"--with-zlib" \
"--with-ssl-dir=/usr/local/openssl" \
"--with-md5-passwords"
# make
# make install
禁止root直接登录，此处先建立一个普通系统用户：
# useradd username
# passwd username
# echo 'Protocol 2' >> /etc/ssh/sshd_config
# echo 'Protocol 2' >> /usr/etc/sshd_config
# echo 'PermitRootLogin no' >> /etc/ssh/sshd_config
# echo 'PermitRootLogin no' >> /usr/etc/sshd_config
# /etc/rc.d/init.d/sshd restart
三、编译安装L.A.M.P环境
1. 下载软件
# cd /usr/local/src
# wget http://download.discuz.net/env/httpd-2.2.3.tar.bz2
# wget http://download.discuz.net/env/mysql-5.0.27.tar.gz
# wget http://download.discuz.net/env/php-5.2.0.tar.bz2
# wget http://download.discuz.net/env/Z ... glibc21-i386.tar.gz
2. 编译安装MySQL
# tar xzvf mysql-5.0.27.tar.gz
# cd mysql-5.0.27
# ./configure \
"--prefix=/usr/local/mysql" \
"--localstatedir=/var/lib/mysql" \
"--with-comment=Source" \
"--with-server-suffix=-Comsenz" \
"--with-mysqld-user=mysql" \
"--without-debug" \
"--with-big-tables" \
"--with-charset=" \ #这个后边需要指定你所需要的字符集参数(gbk,utf8......)
"--with-collation= " \ #字符集校正码(gbk_chinese_ci，......)
"--with-extra-charsets=all" \
"--with-pthread" \
"--enable-static" \
"--enable-thread-safe-client" \
"--with-client-ldflags=-all-static" \
"--with-mysqld-ldflags=-all-static" \
"--enable-assembler" \
"--without-isam" \
"--without-innodb" \
"--without-ndb-debug"
# make
# make install
# useradd mysql
# cd /usr/local/mysql
# bin/mysql_install_db --user=mysql
# chown -R root:mysql .
# chown -R mysql /var/lib/mysql
# cp share/mysql/my-huge.cnf /etc/my.cnf
# cp share/mysql/mysql.server /etc/rc.d/init.d/mysqld
# chmod 755 /etc/rc.d/init.d/mysqld
# chkconfig --add mysqld
# /etc/rc.d/init.d/mysqld start
# bin/mysql -u root password "password_for_root"
3. 编译安装Apache
# cd /usr/local/src
# tar xjvf httpd-2.2.3.tar.bz2
# cd httpd-2.2.3
# ./configure \
"--prefix=/usr/local/apache2
