前端1台Nginx:负载均衡+nfs
中间2台php:php-fpm
后端1台数据库:MySQL
安装略,参考
192.168.112安装Tengine
192.168.1.113/192.168.1.115安装php
192.168.1.114安装MySQL
nfs配置
nfs服务端:192.168.1.112
检查nfs否已安装,这里我已经都安装了。
- [root@linux2 ~]# rpm -qa | grep nfs
- nfs-utils-1.0.9-66.el5
- nfs-utils-lib-1.0.8-7.9.el5
- [root@linux2 ~]# rpm -qa | grep portmap
- portmap-4.0-65.2.2.1
如果你检查发现没有安装,可以使用一下命令进行安装;
- yum -y install nfs-utils portmap
- cat /etc/exports
- /home/wwwroot 192.168.1.0/24(rw)
设置固定端口,方便配置iptables
- cat >> /etc/sysconfig/nfs << EOF
- RQUOTAD_PORT=50001
- LOCKD_TCPPORT=50002
- LOCKD_UDPPORT=50002
- MOUNTD_PORT=50003
- STATD_PORT=50004
- EOF
- iptables -I INPUT 5 -s 192.168.1.0/24 -p tcp -m state --state NEW -m tcp --dport 111 -j ACCEPT
- iptables -I INPUT 6 -s 192.168.1.0/24 -p udp --dport 111 -j ACCEPT
- iptables -I INPUT 7 -s 192.168.1.0/24 -p tcp -m state --state NEW -m tcp --dport 2049 -j ACCEPT
- iptables -I INPUT 8 -s 192.168.1.0/24 -p udp --dport 2049 -j ACCEPT
- iptables -I INPUT 9 -s 192.168.1.0/24 -p tcp -m state --state NEW -m tcp --dport 50001:50004 -j ACCEPT
- iptables -I INPUT 10 -s 192.168.1.0/24 -p udp --dport 50001:50004 -j ACCEPT
- service iptables save
开机自动启动nfs
- chkconfig portmap on
- chkconfig nfs on
- service portmap start
- service nfs start
现在看看启动的端口:
- rpcinfo -p localhost
nfs客户端:192.168.1.113,192.168.1.115
- yum -y install portmap
- chkconfig portmap on
- service portmap start
查看远程nfs共享信息
- showmount -e 192.168.1.112
在/etc/fstab配置文件中添加如下,开机自动挂载
- 192.168.1.112:/home/wwwroot /home/wwwroot nfs defaults 0 0
重新读取/etc/fstab配置文件挂载所有
- mount -a
数据库:192.168.1.114
如:举例网站程序是discuz,创建数据库、赋权,让php能远程访问,如下:
- # mysql -uroot -p
- mysql> create database linuxeye_bbs;
- mysql> grant all privileges on linuxeye_bbs.* to linuxeye_user@'192.168.1.%' identified by 'linuxeye_password';
- mysql> flush privileges;
iptables配置
- iptables -I INPUT 5 -s 192.168.1.0/24 -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
- service iptables save
php:192.168.113
lnmp脚本用的是本机127.0.0.1,为了支持让前端Tengine访问,修改配置文件/usr/local/php/etc/php-fpm.conf
- listen = 192.168.1.113:9000
- listen.allowed_clients = 192.168.1.112
- service php-fpm restart
iptables配置
- iptables -I INPUT 5 -s 192.168.1.112 -p tcp -m state --state NEW -m tcp --dport 9000 -j ACCEPT
- service iptables save
php:192.168.115
同理,修改/usr/local/php/etc/php-fpm.conf
- listen = 192.168.1.115:9000
- listen.allowed_clients = 192.168.1.112
- service php-fpm restart
iptables配置
- iptables -I INPUT 5 -s 192.168.1.112 -p tcp -m state --state NEW -m tcp --dport 9000 -j ACCEPT
- service iptables save
Tengine:192.168.112
配置Tengine负载均衡,在主配置文件/usr/local/tengine/conf/nginx.conf中http段添加如下
- upstream cluster_discuz {
- ip_hash;
- server 192.168.1.112:9000;
- server 192.168.1.115:9000;
- }
添加虚拟主机文件
运行lnmp/vhost.sh,创建虚拟主机(我这里添加的直接是ip192.168.1.112)
修改虚拟主机配置文件/usr/local/tengine/conf/vhost/192.168.1.112.conf
- location ~ .*\.(php|php5)?$ {
- fastcgi_pass cluster_discuz;
- fastcgi_index index.php;
- include fastcgi.conf;
- }
重启nginx
- service nginx restart
