nginx TCP 转发配置

今天有客户需要增加移动线路，但机房刚好移动线路还没有开通，试用了一下转发。效果还不错

客户需求是 服务器只做TCP服务，对应的是7000 7001 7002 7003 转发

先在移动机房增加一台CENTOS 6.5 64位 服务器安装好NGINX等组件

最好是安装1.9版本以上的

一、安装编译工具及库文件

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

#./configure --with-stream
#make

#make install

# /usr/local/nginx/sbin/nginx #启动

测试提示：/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

linux 64位安装nginx后启动出错报以下错误

#/usr/local/nginx/sbin/nginx error while loading shared libraries: libpcre.so.1:cannot open shared object file: No such file or directory

从错误看出是缺少lib文件导致，进一步查看下

1 2 3 4 5 6 7 8 9 10

[root@localhost nginx-1.10.0]# ldd $(which /usr/local/nginx/sbin/nginx) linux-vdso.so.1 => (0x00007fff4d5ff000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fea7e357000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007fea7e120000) libpcre.so.1 => not found libz.so.1 => /lib64/libz.so.1 (0x00007fea7df09000) libc.so.6 => /lib64/libc.so.6 (0x00007fea7db76000) /lib64/ld-linux-x86-64.so.2 (0x00007fea7e57d000) libfreebl3.so => /lib64/libfreebl3.so (0x00007fea7d913000) libdl.so.2 => /lib64/libdl.so.2 (0x00007fea7d70f000)

可以看出 libpcre.so.1 => not found 并没有找到，进入/lib64目录中手动链接下

1 2	[root@localhost /]# cd lib64/ [root@localhost lib64]# ln -s libpcre.so.0.0.1 libpcre.so.1

然后启动nginx就ok了

#pkill -9 nginx 强制结束

# /usr/local/nginx/sbin/nginx -v #查看nginx 支持模块

# /usr/local/nginx/sbin/nginx -t  # 检查语法

配置nginx.conf 在最后添加如入：

stream {

upstream 7000 {
hash $remote_addr consistent;
server 12.12.12.12:7000 max_fails=3 fail_timeout=30s;
}
upstream 7001 {
hash $remote_addr consistent;
server 12.12.12.12:7001 max_fails=3 fail_timeout=30s;
}
        upstream 7002 {
        hash $remote_addr consistent;
        server 12.12.12.12:7002 max_fails=3 fail_timeout=30s;
}
        upstream 7003 {
        hash $remote_addr consistent;
        server 12.12.12.12:7003 max_fails=3 fail_timeout=30s;
}


server {
listen 7000;
proxy_connect_timeout 1s;
proxy_timeout 3s;
proxy_pass 7000;
}

server {
listen 7001;
proxy_connect_timeout 1s;
proxy_timeout 3s;
proxy_pass 7001;
}
server {
        listen 7002;
        proxy_connect_timeout 1s;
        proxy_timeout 3s;
        proxy_pass 7002;
}
server {
        listen 7003;
        proxy_connect_timeout 1s;
        proxy_timeout 3s;
        proxy_pass 7003;
}

}

nginx 重启

#pkill -9 nginx     强行结束进程

# /usr/local/nginx/sbin/nginx 启动进程
