nginx安装

安装类库

yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

安装pcre

PCRE 作用是让 Ngnix 支持 Rewrite 功能。

1、下载 PCRE 安装包，下载地址：

http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

获取

[root@bogon src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

2、解压安装包:

[root@bogon src]# tar zxvf pcre-8.35.tar.gz

3、进入安装包目录

[root@bogon src]# cd pcre-8.35

4、编译安装

[root@bogon pcre-8.35]# ./configure
[root@bogon pcre-8.35]# make && make install

5、查看pcre版本

[root@bogon pcre-8.35]# pcre-config --version

安装 nginx_ upstream_ jvm_route

1、解压nginx-upstream-jvm-route-0.1.tar.gz

tar zxvf nginx-upstream-jvm-route-0.1.tar.gz

安装nginx

1、下载 Nginx、nginx-goodies-nginx-sticky-module-ng-08a395c66e42.zip，下载地址：http://nginx.org/download/nginx-1.6.2.tar.gz

[root@bogon src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz

2、解压安装包

cd /opt/nginx/
tar zxvf nginx-1.11.6.tar.gz
unzip nginx-goodies-nginx-sticky-module-ng-08a395c66e42.zip

3、nginx-sticky-module用来保证同一个客户端访问的都是同一个后端服务器，重命名nginx-goodies-nginx-sticky-module-ng-08a395c66e42为nginx-sticky-module-ng

mv nginx-goodies-nginx-sticky-module-ng-08a395c66e42 nginx-sticky-module-ng

4、编译安装

cd nginx-1.6.2
./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/opt/nginx/pcre-8.35 --add-module=/opt/nginx/nginx-sticky-module-ng

make
make install

5、将nginx执行文件加入path

[root@tjsw10 nginx]# vi /etc/profile
export PATH=$PATH:/usr/local/webserver/nginx/sbin/
[root@tjsw10 nginx]# source /etc/profile

6、查看nginx版本

[root@bogon nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v

nginx配置

创建 Nginx 运行使用的用户 nuser：

    [root@bogon conf]# /usr/sbin/groupadd ngroup 
    [root@bogon conf]# /usr/sbin/useradd -g ngroup nuser

配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容

    [root@bogon conf]#  cat /usr/local/webserver/nginx/conf/nginx.conf
    
    user nuser ngroup;
    worker_processes 4;
    error_log /usr/local/webserver/nginx/logs/nginx_error.log;

       }
      
    }

检查配置文件ngnix.conf的正确性命令：

    [root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t
