Linux 安装 Nginx 并搭建 Tomcat 集群
1.安装Nginx
从官网下载一个nginx 的tar.gz 版
安装方式使用make 安装
第一步:解压
tar -zxvf nginx-1.7.4.tar.gz
第二步:进入nginx-1.7.4,执行./configure 命令
错误一:
[root@localhost nginx-1.7.4]# ./configure
checking for OS
+ Linux 2.6.32-431.el6.x86_64 x86_64
checking for C compiler ... not found
./configure: error: C compiler cc is not found
出现这个错误。
那么就是gcc 包没有安装。安装gcc 吧,骚年。
yum -y install gcc
错误二:
再次执行./configure,又出错
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
安装pcre-devel解决问题
yum install pcre-devel
错误三:
再次执行./configure,接着错
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.
则需要安装“zlib-devel”即可。SSH执行以下命令:
yum install -y zlib-devel
错误四:
还是错,错误提示:
./configure: error: the HTTP cache module requires md5 functions
from OpenSSL library. You can either disable the module by using
--without-http-cache option, or install the OpenSSL library into the system,
or build the OpenSSL library statically from the source with nginx by using
--with-http_ssl_module --with-openssl=<path> options.
解决办法:
yum -y install openssl openssl-devel
正确执行:
再次执行./configure
Configuration summary
+ using system PCRE library
+ OpenSSL library is not used
+ using builtin md5 code
+ sha1 library is not found
+ using system zlib library
安装openssl:
OK,现在可以执行make 了。如果你想使用openssl 功能,sha1 功能。那么安装openssl ,sha1 吧,骚年。安装opensslyum install openssl openssl-devel安装sha1
yum install perl-Digest-SHA1.x86_64
开启ssl 模块 执行./configure --with-http_ssl_module
启用“server+status"页,执行./configure --with-http_stub_status_module
两个都启动,不用我说了。执行./configure --with-http_stub_status_module --with-http_ssl_module
configre 通过执行 make
执行make 命令
执行make install 命令
至此,nginx 执行成功了
配置环境变量:
下来配置环境变量在/etc/profile 中加入:export NGINX_HOME=/usr/local/nginx
export PATH=$PATH:$NGINX_HOME/sbin保存,执行 source /etc/profile ,使配置文件生效。执行nginx -v,就能看到版本了,说明nginx 安装成功了
/usr/local/nginx-1.7.8/sbin/nginx
重启或关闭进程:
/usr/local/nginx-1.7.8/sbin/nginx-s reload
/usr/local/nginx-1.7.8/sbin/nginx-s stop
2. Nignx配置Tomcat
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;
}
}
}
3、启动nginx服务
访问http://192.168.1.208/应用名称
