nginx部署及问题

部署：

安装步骤 (准备相关文件：jemalloc-3.6, pcre-8.37)

yum -y install gcc

yum -y install gcc-c++

yum install make

yum install openssl

yum install openssl-devel

tar xzvf pcre-8.37.tar.gz

cd pcre-8.37

./configure --prefix=/usr/local/pcre-8.37

make

make install

若: checking whether the C compiler works... no

1. yum install gdb

2. yum reinstall gcc

3. yum reinstall glibc

cd /usr/local

tar -xf jemalloc-3.6.0.tar.bz2 -C /usr/local/

tar xzvf tengine-2.1.2.tar.gz

cd /usr/local/tengine-2.1.2

./configure --prefix=/usr/local/tengine \--sbin-path=/usr/local/tengine/sbin/nginx --conf-path=/usr/local/tengine/conf/nginx.conf --error-log-path=/var/log/tengine/error.log --http-log-path=/var/log/tengine/access.log --pid-path=/var/run/tengine.pid --lock-path=/var/lock/subsys/tengine --user=nginx --group=nginx --with-pcre=../pcre-8.37 --with-http_ssl_module --with-http_upstream_check_module --dso-path=/usr/local/tengine/modules --with-jemalloc --with-jemalloc=/usr/local/jemalloc-3.6.0 --add-module=../nginx_concat_module/

make

make install

mkdir -pv /var/tmp/tengine/{proxy,fastcgi,uwsgi}

查询版本： /usr/local/tengine/sbin/nginx ?v

启动：. /usr/local/tengine/sbin/nginx

出错提示：[emerg] getpwnam("nginx") failed

添加用户组->nginx : useradd -r -M nginx

后，使用url访问可看到 “ Welcome to tengine!”,

如：http://192.168.1.103/

实例1:反向代理指定端口

在 server{} 内加入:

listen       80;
server_name  ELK;

proxy_pass http://192.168.1.78:9100/;
}

直接跳过原端口直接访问原带有端口的地址:

即:

http://192.168.1.78/elk_head/   => http://192.168.1.78:9100/

实例2:二级域名反向代理不同后端服务

server {
        listen 80;
        server_name  project1.example.com;
        location / {
                proxy_pass http://127.0.0.1:8001;
        }       
    }
    server {
        listen 80;
        server_name project2.example.com;
        location / {
               proxy_pass http://127.0.0.1:8002;
        }
    }

问题1：mongodb 加载图片只显示部分

原因:查询nginx错误日志，发现nginx proxy_temp目录无权访问

tail -1000f /usr/local/tengine/logs/error.log

/usr/local/tengine/proxy_temp/4/03/0000000034" failed (13: Permission denied)

解决办法：

chown -R nginx:nginx /usr/local/tengine/

问题2：日志文件出现大量head访问日志

在配置文件中关闭head访问日志

            if ($request_method = HEAD) {
                access_log off;
            }
