先上个规划图，自己随便画的，大家也随便看看
192.168.1.119为nginx做反向代理并处理静态页面，apache处理动态页面，nfs共享网站家目录，svn代码管理。
192.168.101为apache处理动态页面，挂载192.168.1.119的共享目录。
192.168.1.96为mysql数据库，允许两台web服务的连接权限。
系统使用centos6.5
一,配置192.168.1.119
1.首先在192.168.1.119上安装nginx+apache+php+nfs+svn
yum install -y nginx httpd php php-mysql nfs-utils portmap subversion
2.修改nginx配置文件
vim /etc/nginx/nginx.conf
user www www;
worker_processes auto;
error_log /home/wwwlogs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 51200;
events
{
use epoll;
worker_connections 51200;
multi_accept on;
}
http
{
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 256k;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
gzip_proxied expired no-cache no-store private auth;
gzip_disable "MSIE [1-6]\.";
#limit_conn_zone $binary_remote_addr zone=perip:10m;
##If enable limit_conn_zone,add "limit_conn perip 10;" to server section.
#log format
log_format access ‘$remote_addr - $remote_user [$time_local] "$request" ‘
‘$status $body_bytes_sent "$http_referer" ‘
‘"$http_user_agent" $http_x_forwarded_for‘;
upstream backend_http {
server 192.168.1.101:80;
server 127.0.0.1:88;
}
server
{
listen 80 default;
#listen [::]:80 default ipv6only=on;
server_name 192.168.1.119;
index index.html index.htm index.php;
root /home/wwwroot/repo;
access_log logs/access.log combined;
#location / {
# try_files $uri @apache;
# }
#location @apache {
# internal;
# proxy_pass http://127.0.0.1:88;
# include proxy.conf;
# }
location ~ [^/]\.php(/|$)
{
proxy_pass http://backend_http;
include proxy.conf;
}
location /nginx_status {
stub_status on;
access_log off;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 12h;
}
access_log /home/wwwlogs/access.log access;
}
include vhost/*.conf;
}
检查配置文件
nginx -t
启动服务
nginx
重新加载配置
nginx -s reload
3.修改apache配置文件
vim /etc/httpd/conf/httpd.conf <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot /home/wwwroot/repo ServerName 192.168.1.119 </VirtualHost> 启动服务 service httpd start chkconfig httpd on
4.创建svn仓库
mkdir /opt/svn && svnadmin create /opt/svn/repo 使用密码认证 vim /opt/svn/repo/conf/svnerve.conf password = 取消这行的注释 添加用户和密码 echo "charlie = charlie" >> /opt/svn/repo/conf/passwd 启动服务 svnserve -d -r /opt/svn 取出svn仓库 cd /home/wwwroot svn co svn://localhost/repo 修改svn更新后直接到网站家目录 cd /opt/svn/repo/hooks cp post-commit.tmpl post-commit vim post-commit export LANG=en_CN.UTF-8 svn update /home/wwwroot/repo --username charlie --password charlie --no-auth-cache #mailer.py commit "$REPOS" "$REV" /path/to/mailer.conf （此行注释） 添加执行权限 chmod +x post-commit
5.配置共享目录
vim /etc/exports /home/wwwroot/repo 192.168.1.0/24(sync,rw,no_root_squash) 启动服务 /etc/init.d/rpcbind start /etc/init.d/nfs start 查看共享目录 exportfs -v 加载共享目录使生效 exportfs -r
二,配置192.168.1.101
6.安装httpd
yum install -y httpd php php-mysql
7.配置apache
vim /etc/httpd/conf/httpd.conf <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot /home/wwwroot/repo ServerName 192.168.1.101 </VirtualHost>
8.挂载共享目录
mkdir /home/wwwroot/repo -pv mount -t nfs 192.168.1.119:/home/wwwroot/repo /home/wwwroot/repo
9.启动服务
service httpd start chkconfig httpd on
三,安装mysql
10.安装mysql
yum install -y mysql mysql-server
11.启动服务
service mysqld start chkconfig mysqld on
12.mysql创建密码
mysqladmin -uroot -password charlie
13.授权用户
mysql -uroot -pcharlie grant all on *.* to [email protected]‘192.168.1.%‘ identified by ‘charlie‘; flush privileges;
四,测试网站
14.svn导出到本地
新建个测试页面
然后访问测试
刷新后版本不同，证明客户端请求php页面会轮询给后端的apache服务器。
如果客户端请求的页面不能保持会话，会经常切换页面导致用户账户登录等问题，所以需要更改nginx配置
添加ip_hash保持会话连接，然后重启nginx -s reload
再次刷新页面不会切换
测试连接数据库，下面页面是测试页
添加并确认
到两台网站服务器上查看是否存在该文件，并检查内容是否一致！
然后访问，证明成功连接后端数据库
