一、Mysql安装
http://mirrors.sohu.com/mysql/MySQL-5.1/ Mysql下载网站 cd /usr/local/src/ wget http://mirrors.sohu.com/mysql/MySQL-5.1/mysql-5.1.72-linux-i686-glibc23.tar.gz tar zxvf mysql-5.1.72-linux-i686-glibc23.tar.gz mv mysql-5.1.72-linux-i686-glibc23 /usr/local/mysql cd ../ ll useradd -s /sbin/nologin -M mysql mkdir -p /data/mysql chown -R mysql:mysql /data/mysql cd mysql/ ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql #初始化数据 echo $? cp /etc/my.cnf /etc/my.cnf.bak #备份配置文件 cp support-files/my-large.cnf /etc/my.cnf #复制配置模板到 vim /etc/my.cnf 编译MySql配置文件 #log-bin=mysql-bin #记录查询、删除、更新数据时记录日志，配置MySql主从时需要，这里暂时不需要，先注释 #binlog_format=mixed #server-id = 1 cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld #复制启动脚本到init.d目录下 vim /etc/init.d/mysqld #编辑启动配置文件，指定数据目录 basedir=/usr/local/mysql datadir=/data/mysql vim /etc/profile.d/path.sh #将mysql添加进PATH路径#!/bin/bashexport PATH=$PATH:/usr/local/mysql/bin/source !$ #更新PATH路径echo $PATH #查看是否生效/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/mysql/bin/ chkconfig --add mysqld #开机启动 chkconfig mysqld on /etc/init.d/mysqld start #启动服务 Starting MySQL... SUCCESS! netstat -tnplu | grep mysql tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 1282/mysqld 如果启动不了，请到 /data/mysql/ 下查看错误日志，这个日志通常是主机名.err. 错误1： Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory 解决方法： yum install libaio-devel –y 错误2： ./bin/my_print_defaults: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory 解决方法: 下载64位数据库 错误3： Starting MySQL.Manager of pid-file quit without updating fi[FAILED] 解决方法： vim /etc/init.d/mysqld #编辑启动配置文件，指定数据目录 basedir=/usr/local/mysql datadir=/data/mysql
二、安装Apache
yum install -y pcre pcre-devel apr apr-devel zlib-devel #安装相关依赖包cd /usr/local/src/ wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.2.31.tar.gz tar xvf httpd-2.2.31.tar.gz cd httpd-2.2.31 ./configure --prefix=/usr/local/apache2 --with-included-apr --enable-so --enable-deflate=shared --enable-expires=shared --enable-rewrite=shared --with-pcre echo $? make echo $? make install echo $?
vim /etc/profile.d/path.sh #将apache添加进PATH路径#!/bin/bashexport PATH=$PATH:/usr/local/mysql/bin/:/usr/local/apache2/bin/source !$ #更新PATH路径 echo $PATH #查看是否生效 /usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/mysql/bin/ apachectl start #启动服务 ps aux | grep httpd #查看进程 root 32632 0.0 0.1 4200 1936 ? Ss 07:54 0:00 /usr/local/apache2/bin/httpd -k start daemon 32670 0.0 0.1 4200 1100 ? S 08:02 0:00 /usr/local/apache2/bin/httpd -k start root 32679 0.0 0.0 6048 776 pts/0 S+ 08:05 0:00 grep httpd netstat -tnlp | grep httpd #查看端口 tcp 0 0 :::80 :::* LISTEN 32632/httpd
2.1、编译参数详解：
--prefix=/usr/local/apache2 #安装目录
--with-included-apr #依赖的组件模块，支持跨平台
--enable-rewrite=shared #动态扩展的模式安装
--with-pcre #正则的支持库
2.2、错误信息：
安装错误
2.2.1.configure: error: mod_deflate has been requested but can not be built due to prerequisite failures 解决方法： yum install zlib-devel -y wget ftp://rpmfind.net/linux/centos/6.7/os/i386/Packages/zlib-devel-1.2.3-29.el6.i686.rpm rpm -ivh zlib-devel-1.2.3-29.el6.i686.rpm
2.2.2checking for APR-util... reconfig configure: error: Cannot use an external APR with the bundled APR-util 解决方法： yum install apr apr-util -y
启动错误：
2.2.3:httpd: apr_sockaddr_info_get() failed for lab-1-c6.7-x32 httpd: Could not reliably determine the server‘s fully qualified domain name, using 127.0.0.1 for ServerName 解决方法： vim /etc/hosts #编辑hosts文件，增加主机名 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 lab-1-c6.7-x32
2.2.4：httpd: Could not reliably determine the server‘s fully qualified domain name, using lab-1-c6.7-x32 for ServerName 解决方法： cp /usr/local/apache2/conf/httpd.conf /usr/local/apache2/conf/httpd.conf.bak #备份配置文 找到以下内容，取消注释#ServerName www.example:80 /usr/local/apache2/bin/apachectl restart #重启服务
2.3、配置Apache
apachectl -t #查看Apache配置文件语法是否错误
apachectl start\restart\stop\graceful 开启\重启\关闭\重载
apachectl -M #查看Apache模块
ls /usr/local/apache2/modules/ #绿色的是动态加载模块
httpd.exp mod_deflate.so mod_expires.so mod_rewrite.so
ls /usr/local/apache2/bin/httpd #橙色的是静态态加载模块
/usr/local/apache2/bin/httpd
apachectl -l #查看Apache静态模块和工作模式
三、Apache的工作模式
/usr/local/src/httpd-2.2.31/./configure --help | less
--with-mpm=MPM Choose the process model for Apache to use.
MPM={beos|event|worker|prefork|mpmt_os2|winnt}#常见的工作模式有worker、prefork两种，2.2默认是prefork，2.4默认是event
/usr/local/apache2/bin/apachectl -l #查看Apache当前工作模式 prefork.c
3.1、prefork模式
[root@lab-1-c6 ~]# ps aux | grep httpd #一个主进程，多个子进程 root 32632 0.0 0.1 4200 1944 ? Ss 07:54 0:00 /usr/local/apache2/bin/httpd -k start daemon 32696 0.0 0.1 4200 1100 ? S 08:21 0:00 /usr/local/apache2/bin/httpd -k start daemon 32697 0.0 0.1 4200 1100 ? S 08:21 0:00 /usr/local/apache2/bin/httpd -k start daemon 32698 0.0 0.1 4200 1100 ? S 08:21 0:00 /usr/local/apache2/bin/httpd -k start daemon 32699 0.0 0.1 4200 1100 ? S 08:21 0:00 /usr/local/apache2/bin/httpd -k start daemon 32700 0.0 0.1 4200 1100 ? S 08:21 0:00 /usr/local/apache2/bin/httpd -k start root 332 0.0 0.0 6048 772 pts/1 S+ 08:40 0:00 grep httpd
3.2、worker模式
不仅有主进程和子进程，而且每个子进程下面还有线程
线程的优点：
线程之间共享一段内存，当高并发的情况下，线程很占优势，占用很少的内存
线程的缺点：
一个进程的所有内存会共享给下面所有的线程，若进程下面的某一个线程出现故障，则进程下面其他所有的线程就会收到牵连
3.3、event模式
和worker一样，也是线程的工作形式，但是优化了许多
3.4、worker、prefork和event模式对比
prefork：进程之间故障，不会影响其他进程，但高并发时占用内存较大
worker：同一进程下的线程故障，会影响整个进程，但高并发时占用内存可观
3.5、Apache工作模式的配置
--with-mpm=worker #编译时指定工作模式
四、PHP编译安装
cd /usr/local/src/ wget http://mirrors.sohu.com/php/php-5.5.31.tar.gz tar xf php-5.5.31.tar.gz yum install zlib libxml libjpeg freetype libpng gd curl libiconv zlib-devel libxml2-devel libjpeg-devel freetype-devel libpng-devel gb-devel gb-devel curl-devel libxslt-devel openssl-devel bzip2 bzip2-devel libmcrypt-devel.x86_64 -y #安装依赖包 cd php-5.5.31 ./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 --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif --disable-ipv6 #编译参数 echo $? make echo $? make install echo $?

cp /usr/local/src/php-5.5.31/php.ini-production /usr/local/php/etc/php #复制配置文件 apachectl graceful 重新加载PHP配置文件
六、Discuz安装
mkdir /data/www cd /data/www wget http://download.comsenz.com/DiscuzX/3.2/Discuz_X3.2_SC_GBK.zip unzip Discuz_X3.2_SC_GBK.zip mv upload/* ./ rm -rf readme/ utility/ upload/ Discuz_X3.2_SC_GBK.zip vim /usr/local/apache2/conf/httpd.conf 找到以下内容，取消注释 #Include conf/extra/httpd-vhosts.conf #启用虚拟主机配置文件 cp /usr/local/apache2/conf/extra/httpd-vhosts.conf /usr/local/apache2/conf/extra/httpd-vhosts.conf.bak #备份配置文件 vim /usr/local/apache2/conf/extra/httpd-vhosts.conf <VirtualHost *:80> #ServerAdmin webmaster@dummy-host.example.com #管理员邮箱，不使用先注释 DocumentRoot "/data/www" #指定文件目录 ServerName www.szk.com #指定域名 ServerAlias www.test.com #指定域名别名 #ErrorLog "logs/dummy-host.example.com-error_log" #错误日志和访问日志先注释 #CustomLog "logs/dummy-host.example.com-access_log" common </VirtualHost> apachectl -t #检查配置文件语法 httpd: Could not reliably determine the server‘s fully qualified domain name, using lab-1-c6.7-x32 for ServerName Syntax OK vim /usr/local/apache2/conf/httpd.conf 找到以下内容，取消注释 #ServerName www.example:80 /usr/local/apache2/bin/apachectl start 访问报403错误，不允许访问 vim /usr/local/apache2/conf/httpd.conf #找到Deny from all改成Allow from all /usr/local/apache2/bin/apachectl graceful #重载服务,进入Discuz安装页面，发现很多目录没有权限
