Nginx升级-从nginx-1.8.1到nginx-1.12.2
原来是源码编译安装的
升级过程中，make时报错
……

make[1]: Leaving directory `/data/nginx-1.12.2'

[root@test01 nginx-1.12.2]#
参考网上资料进行文件修改后成功解决
第一次修改：
ngx_http_sticky_misc.c 的281行修改如下
原
digest->len = ngx_sock_ntop(in, digest->data, len, 1);
改后
digest->len = ngx_sock_ntop(in, sizeof(struct sockaddr_in), digest->data, len, 1);
ngx_http_sticky_module.c文件也进行修改
第6行添加：
#include
第340行左右修改（iphp->rrp.current = iphp->selected_peer;）为：
if (peer && selected_peer >= 0) {
ngx_log_debug(NGX_LOG_DEBUG_HTTP, pc->log, 0, "[sticky/get_sticky_peer] peer found at index %i", selected_peer);
#if defined(nginx_version) && nginx_version >= 1009000
iphp->rrp.current = peer;
#else
iphp->rrp.current = iphp->selected_peer;
#endif
但是再次编译又有新的报错：
rc/http -I src/http/modules \
-o objs/addon/nginx-sticky-module-1.25/ngx_http_sticky_misc.o \

[root@test01 nginx-1.12.2]#
第二次修改：
ngx_http_sticky_misc.c中新增2个模块
#include
#include
#include
#include
#include
#include
#include
#include
#include "ngx_http_sticky_misc.h"
之后再重新编译就不会出错了。
