咱们以模拟实际需求的形式来复习。需求以下：
1. 准备两台centos 6，其中一台机器跑mysql，另一台机器跑apache和nginx + php
2. 同时安装apache和nginx，其中nginx启动80端口，用来跑静态对象（图片、js、css），apache监听88端口，负责跑动态页（php相关的），而且须要由nginx代理对外访问
3. mysql服务器须要开启慢查询日志
4. 搭建discuz、wordpress以及phpmyadmin，域名分别为bbs.abc.com, blog.abc.com, pma.abc.com
5. 配置discuz的伪静态(nginx)
6. apache不须要记录日志，nginx记录日志，但不记录图片等静态页的日志，而且配置日志切割
7. 配置图片防盗链(nginx)
8. 配置图片缓存7天，js，css缓存1天(nginx)
9. discuz和wordpress访问后台限制一下ip白名单，好比只容许192.168.1.100访问(nginx)
10. phpmyadmin整个站点须要配置用户认证(nginx)
11. 写一个mysql备份的脚本，天天5点执行，须要远程拷贝到web机器上
12. 把除了百度、google外的其余常见搜索引擎蜘蛛封掉，好比（bingbot/2.0、Sogou web spider/4.0、360Spider、YisouSpider、YandexBot/3.0）(nginx)你们好，里面的图片仅供参考，只是一种思路，不要照搬！！
对代理名词的理解：举个例子吧！你是供应商，你手下有一个业务代理，它帮你销售东西出去，若是你想不卖这个东西给某个公司或者地方，是否是给代理说说就行了。那我这里apache是供应商，nginx是代理商，因此nginx响应客户端，他知道客户的请求
实验环境：
一、VMware Workstation 10
二、设备A：MySQL，IP地址：192.168.137.102，HostName：mysql
三、设备B：LAMP环境+nginx代理，IP地址：192.168.137.107，HostName：lanp
四、Linux发行版：Centos 6.7 x86_64；
五、Nginx：http://nginx.org/download/nginx-1.6.2.tar.gz
六、Apache：httpd-2.2.16.tar.gz
七、PHP：php-5.3.28.tar.gz
八、MySQL:mysql-5.5.42-linux2.6-x86_64.tar.gz
九、discuz：Discuz_X3.2_SC_UTF8.zip
十、wordpress：wordpress-4.2.2-zh_CN.tar.gz
十一、phpmyadmin：phpMyAdmin-4.0.8-all-languages.zip
实验步骤：
设备A：mysqljavascript
cd /usr/local/src/ tar zxvf mysql-5.5.42-linux2.6-x86_64.tar.gz mv mysql-5.5.42-linux2.6-x86_64 /usr/local/mysql cd /usr/local/mysql mkdir -p /data/mysql useradd -s /sbin/nologin -M mysql chown -R mysql:mysql /data/mysql cp support-files/my-large.cnf /etc/my.cnf cp support-files/mysql.server /etc/init.d/mysqld chmod 755 /etc/init.d/mysqld vi /etc/init.d/mysql，basedir=/usr/local/mysql，datadir=/data/mysql ./scripts/mysql_install_db –user=mysql –datadir=/data/mysql vim /etc/profile.d/mysql.sh加入export PATH=$PATH:/usr/local/mysql/bin chkconfig –add mysqld chkconfig mysqld on service mysqld start
登陆mysql受权：grant all on *.* to ‘aming’@’192.168.137.107’ identified by ‘aminglinux.com’;php
设备B：LAMP
1. 安装apachecss
cd /usr/local/src/ tar zvxf httpd-2.2.16.tar.gz cd httpd-2.2.16 ./configure –prefix=/usr/local/apache2 –enable-mods-shared=most –enable-so make&make install
apache加入chkconfightml
cp /usr/local/apache2/bin/apachectl /etc/init.d/httpd vim /etc/init.d/httpd
在第一行#!/bin/sh下增长两行文字java
# chkconfig: 35 70 30 # description: Apache chkconfig –level 35 httpd on
2. 安装phpnode
cd /usr/local/src/ tar zxvf php-5.3.28.tar.gz cd php-5.3.28 ./configure –prefix=/usr/local/php –with-apxs2=/usr/local/apache2/bin/apxs –with-config-file-path=/usr/local/php/etc –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 –with-mysql=mysqlnd –with-mysqli=mysqlnd –with-pdo-mysql=mysqlnd make&make install cp /usr/local/src/php-5.3.28/php.ini-production /usr/local/php/etc/php.ini
三、 配置apache结合phpmysql
vim /usr/local/apache2/conf/httpd.conf
找到:linux
AddType application/x-gzip .gz .tgz
在该行下面添加:nginx
AddType application/x-httpd-php .php
找到:web
DirectoryIndex index.html
将该行改成:
DirectoryIndex index.html index.htm index.php
找到:
#ServerName www.example.com:80
修改成:
ServerName localhost:80
vim /usr/local/apache2/conf/httpd.conf找到：
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
改成：
Options FollowSymLinks
AllowOverride None
Order deny,allow
Allow from all
测试LAMP环境：在浏览器访问192.168.137.107，若是显示IT Works！表示LAMP环境搭建成功
mkdir data cd data
在data目录分别建立bbs、blog、pma目录
4.解压discuz并把upload下的内容移到bbs下
cd /usr/local/src unzip Discuz_X3.2_SC_UTF8.zip mv upload/* /data/bbs
5.解压wordpress并把wordpress下的内容移到blog下
[root@lanp src]# tar zxvf wordpress-4.2.2-zh_CN.tar.gz [root@lanp src]# mv wordpress/* /data/blog
6.解压phpmyadmin并把phpMyAdmin-4.0.8-all-languages下的内容移到pma下
[root@lanp src]# unzip phpMyAdmin-4.0.8-all-languages.zip [root@lanp src]# mv phpMyAdmin-4.0.8-all-languages/* /data/pma
7.把apache端口改为88：进入apache主配置文件，把lisen 80改为88
8.[root@lanp ~]# vim /usr/local/apache2/conf/extra/httpd-vhosts.conf（添加三个虚拟主机，并把80端口改为88）
#ServerAdmin webmaster@dummy-host.example.com DocumentRoot “/data/bbs” ServerName bbs.abc.com #ServerAlias www.dummy-host.example.com ErrorLog “logs/bbs.abc.com-error_log” CustomLog “logs/bbs.abc.com-access_log” common #ServerAdmin webmaster@dummy-host2.example.com DocumentRoot “/data/blog” ServerName blog.abc.com ErrorLog “logs/blog.abc.com-error_log” CustomLog “logs/blog.abc.com-access_log” common #ServerAdmin webmaster@dummy-host2.example.com DocumentRoot “/data/pma” ServerName pma.abc.com ErrorLog “logs/pma.abc.com-error_log” CustomLog “logs/pma.abc.com-access_log” common
检查配置文件是否有语法错误：
[root@lanp ~]# /usr/local/apache2/bin/apachectl -t
Syntax OK
检查88端口是否监听
[root@lanp ~]# /usr/local/apache2/bin/apachectl restart
[root@lanp ~]# netstat -lnp
9.在真机win上的host文件里绑定ip和虚拟主机域名（host文件路径：C/windows/System32/drivers/etc/hosts
192.168.137.107 bbs.abc.com blog.abc.com pma.abc.com
10.安装discuz
在浏览器访问bbs.abc.com/install/，会出现discuz图形安装界面，点我赞成，出现不少目录不可写，为啥不可写呢？由于ps aux |grep httpd，httpd是以daemon用户运行。因此须要把discuz中不可写的目录的属主和属组改为daemon，chown -R daemon:daemon config/ data uc_client/data uc_server/data
回到浏览器刷新，下一步，再全新安装discuz
在mysql中建立discuz库并受权一个用户
mysql> create database discuz; mysql> grant all on *.* to ‘aming’@’192.168.137.107’ identified by ‘aminglinux.com’; mysql> flush privileges;
回到discuz浏览器，数据库名为discuz，数据库用户名为aming，数据库密码aminglinux.com
到此discuz论坛安装完毕
11.安装wordpress
在mysql中建立blog库
mysql> create database blog;
在浏览器中访问blog.abc.com：88进行安装http://s1.51cto.com/wyfs02/M00/78/4C/wKiom1Z6BiTyW7WFAAD-3ngXLGQ414.png根据错误提示，在blog目录下建立wp-config.php而后把浏览器中方框内信息拷贝至wp-config.php目录
12.安装phpmyadmin
cp libraries/config.default.php config.inc.php
更改
$cfg[‘Servers’][$i][‘user’] = ‘root’; $cfg[‘Servers’][$i][‘password’] = ‘yourrootpassword’; $cfg[‘Servers’][$i][‘host’] = ‘yourdbip’; $cfg[‘Servers’][$i][‘auth_type’] = ‘config’;##认证模式
在浏览器中访问pma.abc.com：88进行安装
13.安装nginx
[root@lanp src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz [root@lanp src]# tar zxvf nginx-1.6.2.tar.gz [root@lanp nginx-1.6.2]# ./configure –prefix=/usr/local/nginx –with-pcre make &make install
nginx启动脚本和配置文件
vim /etc/init.d/nginx //加入以下内容 #!/bin/bash # chkconfig: – 30 21 # description: http service. # Source Function Library . /etc/init.d/functions # Nginx Settings NGINX_SBIN=”/usr/local/nginx/sbin/nginx” NGINX_CONF=”/usr/local/nginx/conf/nginx.conf” NGINX_PID=”/usr/local/nginx/logs/nginx.pid” RETVAL=0 prog=”Nginx” start() { echo -n $”Starting $prog: “ mkdir -p /dev/shm/nginx_temp daemon $NGINX_SBIN -c $NGINX_CONF RETVAL=$? echo return $RETVAL } stop() { echo -n $”Stopping $prog: “ killproc -p $NGINX_PID $NGINX_SBIN -TERM rm -rf /dev/shm/nginx_temp RETVAL=$? echo return $RETVAL } reload(){ echo -n $”Reloading $prog: “ killproc -p $NGINX_PID $NGINX_SBIN -HUP RETVAL=$? echo return $RETVAL } restart(){ stop start } configtest(){ $NGINX_SBIN -c $NGINX_CONF -t return 0 } case “$1” in start) start ;; stop) stop ;; reload) reload ;; restart) restart ;; configtest) configtest ;; *) echo $”Usage: $0 {start|stop|reload|restart|configtest}” RETVAL=1 esac exit $RETVAL
chmod 755 /etc/init.d/nginx chkconfig –add nginx chkconfig nginx on service nginx start service nginx configtest#（检测配置文件，configtest至关于-t） vim /usr/local/nginx/conf/nginx.conf #清空原来的配置，加入以下内容
user nobody nobody; worker_processes 2; error_log /usr/local/nginx/logs/nginx_error.log crit; pid /usr/local/nginx/logs/nginx.pid; worker_rlimit_nofile 51200; events { use epoll; worker_connections 6000; } http { include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 3526; server_names_hash_max_size 4096; log_format combined_realip ‘$remote_addr $http_x_forwarded_for [$time_local]’ ‘$host “$request_uri” $status’ ‘”$http_referer” “$http_user_agent”‘; sendfile on; tcp_nopush on; keepalive_timeout 30; client_header_timeout 3m; client_body_timeout 3m; send_timeout 3m; connection_pool_size 256; client_header_buffer_size 1k; large_client_header_buffers 8 4k; request_pool_size 4k; output_buffers 4 32k; postpone_output 1460; client_max_body_size 10m; client_body_buffer_size 256k; client_body_temp_path /usr/local/nginx/client_body_temp; proxy_temp_path /usr/local/nginx/proxy_temp; fastcgi_temp_path /usr/local/nginx/fastcgi_temp; fastcgi_intercept_errors on; tcp_nodelay on; gzip on; gzip_min_length 1k; gzip_buffers 4 8k; gzip_comp_level 5; gzip_http_version 1.1; gzip_types text/plain application/x-javascript text/css text/htm application/xml; include vhosts/*.conf; } cd /usr/local/nginx/conf/ mkdir vhosts touch discuz.conf touch pma.conf touch blog.conf 14.discuz.conf server { listen 80; server_name bbs.abc.com; index index.html index.htm index.php; root /data/bbs; #根据user_agent控制 if ($http_user_agent ~ ‘bingbot/2.0|MJ12bot/v1.4.2|Spider/3.0|YoudaoBot|Tomato|Gecko/20100315’){ return 403; } location ~ admin.php { allow 192.168.31.141; deny all; proxy_pass http://127.0.0.1:88; proxy_set_header Host $host; } location ~ \.php$ { proxy_pass http://127.0.0.1:88; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location ~ .*\.(js|css)?$ { expires 24h; access_log off; } location ~* ^.+\.(gif|jpg|png|swf|flv|rar|zip|doc|pdf|gz|bz2|jpeg|bmp|xls)$ { expires 7d; valid_referers none blocked server_names *.abc.com *.a.com *.b.com *.baidu.com\ *.google.com *.google.cn *.soso.com ; if ($invalid_referer) { return 403; #rewrite ^/ http://www.example.com/nophoto.gif; } access_log off; } rewrite ^([^\.]*)/topic-(.+)\.html$ $1/portal.php?mod=topic&topic=$2 last; rewrite ^([^\.]*)/forum-(\w+)-([0-9]+)\.html$ $1/forum.php?mod=forumdisplay&fid=$2&page=$3 last; rewrite ^([^\.]*)/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html$ $1/forum.php?mod=viewthread&tid=$2&extra=page%3D$4&page=$3 last; rewrite ^([^\.]*)/group-([0-9]+)-([0-9]+)\.html$ $1/forum.php?mod=group&fid=$2&page=$3 last; rewrite ^([^\.]*)/space-(username|uid)-(.+)\.html$ $1/home.php?mod=space&$2=$3 last; rewrite ^([^\.]*)/(fid|tid)-([0-9]+)\.html$ $1/index.php?action=$2&value=$3 last; access_log /home/logs/discuz.log combined_realip;
检测nginx配置文件：
/usr/local/nginx/sbin/nginx -t
重启
nginx：service nginx restart
在浏览器访问bbs.abc.com，是能够正常进入discuz页面的。
15.blog.conf配置(参考 http://www.upupw.net/nginxhelp/n33.html)
server { listen 80; server_name blog.abc.com; index index.html index.htm index.php; root /data/blog; location /wp-admin/ { allow 127.0.0.1; deny all; location ~ \.php$ { proxy_pass http://127.0.0.1:88; proxy_set_header Host $host; } } location / { proxy_pass http://127.0.0.1:88/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }
检测nginx配置文件是否有语法错误：
/usr/local/nginx/sbin/nginx -t
重启nginx：
service nginx restart
在浏览器访问：blog.abc.com，是能够访问的
16.配置pma.conf
server { listen 80; server_name pma.abc.com; index index.html index.htm index.php; root /data/pma; location / { auth_basic “Auth”; auth_basic_user_file /usr/local/nginx/conf/htpasswd; location ~ \.php$ { proxy_pass http://127.0.0.1:88; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } }
检测nginx配置文件是否有语法错误：
/usr/local/nginx/sbin/nginx -t
重启nginx：
service nginx restart
浏览器访问：pma.abc.com是能够访问到的
1七、配置nginx的日志切割
[root@lanp vhosts]# vim /usr/local/sbin/logrotate.sh #!/bin/bash d=`date -d “-1 day” +%Y%m$d` /bin/mv /home/logs/discuz.log /home/logs/discuz_$d.log /etc/init.d/nginx reload >/dev/null 2>/dev/null cd /home/logs gzip discuz_$d.log
1八、mysql备份脚本无需密码经过ssh执行rsync来同步文件的方法能够参考http://www.jb51.net/article/60192.htm
vim mysqlbak.sh #!/bin/bash source /etc/profile d=`date +%F` /usr/local/mysql/bin/mysqldump -uroot -p838024 wordpress >/data/mysqlbak/$d.wordpresssql /usr/local/mysql/bin/mysqldump -uroot -p838024 discuz >/data/mysqlbak/$d.discuzsql /usr/local/mysql/bin/mysqldump -uroot -p838024 phpmyadmin >/data/mysqlbak/$d.phpmyadminsql rsync -avLupz -e “ssh -p 22” /data/mysqlbak/ 192.168.137.107:/tmp/
再把脚本放进crontab计划任务
chmod a+x mysqlbak.sh crontab -e */3 * * * * /root/shell/mysqlbak.sh
关于rsync命令：
本地和远程须要安装rsync和openssh-clients
yum install rsync和yum install openssh-clients
