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

……

c/Http -I src/http/modules \

-o objs/src/http/modules/ngx_http_stub_status_module.o \

src/http/modules/ngx_http_stub_status_module.c

/data/nginx-sticky-module-1.25/ngx_http_sticky_module.c:340: error: assignment makes pointer from integer without a cast

make[1]: *** [objs/addon/nginx-sticky-module-1.25/ngx_http_sticky_module.o] Error 1

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

make: *** [build] Error 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 <nginx.h>

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 \

/data/nginx-sticky-module-1.25/ngx_http_sticky_misc.c

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

make: *** [build] Error 2

[root@test01 nginx-1.12.2]# 

第二次修改：

ngx_http_sticky_misc.c中新增2个模块<openssl/sha.h> 和 <openssl/md5.h>

#include <nginx.h>

#include <ngx_config.h>

#include <ngx_core.h>

#include <ngx_http.h>

#include <ngx_md5.h>

#include <ngx_sha1.h>

#include <openssl/sha.h>

#include <openssl/md5.h> 

#include "ngx_http_sticky_misc.h"

之后再重新编译就不会出错了。
