php主机的复制
-------------------
servera:
scp /etc/sysconfig/spawn-fcgi 172.25.8.11:/etc/sysconfig/
tar czf /tmp/lemp.com.tgz /usr/share/nginx/lemp.com/
scp /tmp/lemp.com.tgz root@172.25.8.11:~
vim /etc/nginx/conf.d/www.lemp.com.conf
systemctl restart nginx.service
systemctl stop spawn-fcgi.service
vim /etc/nginx/nginx.conf
http {
   include       /etc/nginx/mime.types;
   default_type  application/octet-stream;
   log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                     '$status $body_bytes_sent "$http_referer" '
                     '"$http_user_agent" "$http_x_forwarded_for"';
   access_log  /var/log/nginx/access.log  main;
   sendfile        on;
   #tcp_nopush     on;
   keepalive_timeout  65;
   #gzip  on;
   upstream php_pool {
server 172.25.8.11:9000;
server 172.25.8.12:9000；
}
vim /etc/nginx/conf.d/www.lemp.com.conf
server {
listen 80;
server_name www.lemp.com;
root /usr/share/nginx/lemp.com;
index index.php index.html index.htm;
location ~ \.php$ {
#fastcgi_pass 127.0.0.1:9000;
#fastcgi_pass 172.25.8.11:9000;
fastcgi_pass php_pool;  #
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/lemp.com$fastcgi_script_name;
include fastcgi_params;
}
}
--------------------------
serverb:
scp /etc/sysconfig/spawn-fcgi 172.25.8.12:/etc/sysconfig/
tar czf /tmp/lemp.com.tgz /usr//share/nginx/lemp.com/
scp /tmp/lemp.com.tgz root@172.25.8.12:~
-------------------
serverc:
tar xf lemp.com.tgz -C /
ll /usr/share/nginx/lemp.com/
groupadd nginx -g 994
useradd nginx -u 996 -g nginx
systemctl start spawn-fcgi.service
mount 172.25.254.250:/content /mnt
cd /mnt/ula/nginx/nginx-rpms
rpm -ivh spawn-fcgi-1.6.3-5.el7.x86_64.rpm
yum -y install php php-mysql
systemctl start spawn-fcgi.service
测试：
serverb：
cd /usr/share/nginx/lemp.com/
echo bbbb>test.php
serverc：
cd /usr/share/nginx/lemp.com/
echo cccc>test.php
-----
www.lemp.com/test.php
cccc和bbbb交替显示代表成功
访问
www.lemp.com
发帖上传文件
图片会传到其中一个php服务器，另一个php服务器则无法访问到图片
find ./lemp.com/data/* -name "*.gif"
-------------------------------
数据的共享
serverb:
scp /tmp/lemp.com.tgz root@172.25.8.19:~
tar czf /tmp/lemp.com.tgz /usr/share/nginx/lemp.com/
serverj:
yum -y install nfs-utils
tar -xf lemp.com.tgz -C / 从b中网站根目录全备份拷贝过来
vim /etc/exports
/usr/share/nginx/lemp.com 172.25.8.0/24(rw,async)
systemctl start nfs
serverb:
mount 172.25.8.19:/usr/share/nginx/lemp.com /usr/share/nginx/lemp.com
serverc:
mount 172.25.8.19:/usr/share/nginx/lemp.com /usr/share/nginx/lemp.com
