一.nginx代理服务器部署
1.在nginx代理服务器上装上nginx软件（下载地址：http://nginx.org/en/download.html）
2.在linux系统中下载nginx安装包
切换目录：cd /usr/local
执行如下命令：wget http://nginx.org/download/nginx-1.10.3.tar.gz
3.解压nginx压缩包并重命名
tar -zxvf nginx-1.10.3.tar.gz ps:解压缩包
rm nginx-1.10.3.tar.gz ps:删除下载的压缩包
mv nginx-1.10.3.tar.gz nginx ps:重命名
4.进入nginx目录
编译安装nginx
执行命令：.cd nginx ps:切换到nginx软件目录
./configure --prefix=/usr/local/nginx ps:配置nginx软件
make ps:编译nginx软件
make install ps:安装nginx软件
5.新建日志目录及文件
在nginx目录下新建logs
mkdir logs 新建logs目录
cd logs
vi error.log 新建error.log文件
vi access.log 新建access.log文件
6.修改nginx/conf下面的nginx.conf文件配置代理，及负载均衡配置
#user nobody;
worker_processes 1; #工作进程数 #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include 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 logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; #配置负载均衡 域名localhost后面的也要保持一致 #通过ip哈希来实现负载均衡 upstream localhost { #ip_hash server 192.168.33.11 weight=2; #敷在服务器1 weight权重越大访问的几率越高 server 192.168.33.12:80;#敷在服务器2 可以指定端口 server 192.168.33.13;#敷在服务器3 } server { listen 80; server_name localhost; #与upstream后面的保持一致 #charset koi8-r; #access_log logs/host.access.log main; location / { #设置主机头和客户端真实地址，以便服务器获取客户端真实IP proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #禁止缓存 proxy_buffering off; #设置反向代理地址同时与上面的域名保持一致 proxy_pass http://localhost; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } }
6.启动nginx代理
./sbin/nginx ps:启动nginx代理服务
./sbin/nginx -s reload 重启nginx代理服务
可能遇到的问题：
80端口被占用：
netstat -an |grep 80 查看端口
ps -ef |grep nginx 查看服务进程
kill -9 进程号 删死进程
二，负载服务器部署（以192.168.33.13服务器为例，其它服务器一样）
1.在nginx代理服务器上装上nginx软件（下载地址：http://nginx.org/en/download.html）
2.在linux系统中下载nginx安装包
切换目录：cd /usr/local
执行如下命令：wget http://nginx.org/download/nginx-1.10.3.tar.gz
3.解压nginx压缩包并重命名
tar -zxvf nginx-1.10.3.tar.gz ps:解压缩包
rm nginx-1.10.3.tar.gz ps:删除下载的压缩包
mv nginx-1.10.3.tar.gz nginx ps:重命名
4.进入nginx目录
编译安装nginx
执行命令：.cd nginx ps:切换到nginx软件目录
./configure --prefix=/usr/local/nginx ps:配置nginx软件
make ps:编译nginx软件
make install ps:安装nginx软件
5.新建日志目录及文件
在nginx目录下新建logs
mkdir logs 新建logs目录
cd logs
vi error.log 新建error.log文件
vi access.log 新建access.log文件
7.配置nginx.conf文件
#user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 80; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { index index.html index.htm index.php; root html; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ .php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ .php$ { root html;#指定php文件存放的目录 fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; # $document_root 代表当前请求在root指令中指定的值 include fastcgi_params; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
8.启动nginx代理
./sbin/nginx ps:启动nginx代理服务
./sbin/nginx -s reload 重启nginx代理服务
9.安装 php和php-fpm管理工具
yum install php 安装php
yum install php-fpm安装fpm管理工具
10.启动php-fpm
systemctl start php-fpm
service php-fpm status 查看服务状态
11.部署完成之后访问代理服务器http://192.168.33.10/test.php
ps:如果访问不通关闭防火墙 或者防火墙打开需要的80端口 关闭防火墙的命令为：systemctl stop firewalld.service
问题处理：
访问报错connect() failed (111: Connection refused) 可能是因为php-fpm未启动
