时间:2016-04-03 20:42 来源:linux.it.net.cn 作者:IT网

安装中文包支持

yum groupinstall chinese-support

在CentOS linux 正常配置 tomcat7

启动tomcat7，访问地址为：

192.168.1.207:8080

192.168.1.208:8080

下载nginx 相关版本，地址如下：http://nginx.org/en/download.html，个人使用的是nginx-1.6.2.tar.gz
将nginx 安装文件上传至linux 服务器。
执行命令进行解压：tar -zxvf nginx-1.6.2.tar.gz
安装nginx必须的相关包命令：
yum install -y pcre-devel openssl-devel
yum install gcc-c++

配置nginx安装环境：

执行如下命令：

cd nginx-1.6.2
./configure --with-http_stub_status_module --with-http_ssl_module

如果出现以下信息表示配置安装环境成功。

nginx path prefix: "/usr/local/nginx"
nginx binary file: "/usr/local/nginx/sbin/nginx"
nginx configuration prefix: "/usr/local/nginx/conf"
nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
nginx pid file: "/usr/local/nginx/logs/nginx.pid"
nginx error log file: "/usr/local/nginx/logs/error.log"
nginx http access log file: "/usr/local/nginx/logs/access.log"
nginx http client request body temporary files: "client_body_temp"
nginx http proxy temporary files: "proxy_temp"
nginx http fastcgi temporary files: "fastcgi_temp"
nginx http uwsgi temporary files: "uwsgi_temp"
nginx http scgi temporary files: "scgi_temp"

安装nginx

执行命令：make && make install

出现如下信息表示安装成功：

test -f '/usr/local/nginx/conf/nginx.conf' || cp conf/nginx.conf '/usr/local/nginx/conf/nginx.conf'
cp conf/nginx.conf '/usr/local/nginx/conf/nginx.conf.default'
test -d '/usr/local/nginx/logs' || mkdir -p '/usr/local/nginx/logs'
test -d '/usr/local/nginx/logs' || mkdir -p '/usr/local/nginx/logs'
test -d '/usr/local/nginx/html' || cp -R html '/usr/local/nginx'
test -d '/usr/local/nginx/logs' || mkdir -p '/usr/local/nginx/logs'
make[1]: Leaving directory `/web/nginx-1.6.2'

启动：/usr/local/nginx/sbin/nginx
关闭：/usr/local/nginx/sbin/nginx -s stop

重启 nginx 服务:/usr/nginx/sbin/nginx -s reload

配置nginx负载均衡

执行命令：vi /usr/local/nginx/sbin/nginx/conf/nginx.conf

修改为：

worker_processes 2;
events {
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
#start
upstream 192.168.1.208{
#解决session的问题
ip_hash;
server 192.168.1.207:8080 weight=1;
server 192.168.1.208:8080 weight=1;
}
#end
server {
listen 80;
server_name 192.168.1.208;
location / {
root html;
index index.html index.htm;
#请求转向mysvr 定义的服务器列表
proxy_pass http://192.168.1.208;
proxy_redirect default;
#跟代理服务器连接的超时时间，必须留意这个time out时间不能超过75秒，当一台服务器当掉时，过10秒转发到另外一台服务器。
proxy_connect_timeout 10;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}

保存退出。

启动nginx服务，

访问http://192.168.1.208/应用名称
