nginx有两个日志格式，分别是$time_local和$time_iso8601，均未能满足"1970-09-28 12:00:00"的格式，通过修改源码重新编译满足需求：

1、vi /root/pkg/nginx-1.10.2/src/http/modules/ngx_http_log_module.c

static ngx_http_log_var_t  ngx_http_log_vars[] = {    ...    { ngx_string("time_iso8601"), sizeof("1970-09-28T12:00:00+06:00") - 1,                          ngx_http_log_iso8601 },    ...};

改为：

static ngx_http_log_var_t  ngx_http_log_vars[] = {    ...    { ngx_string("time_iso8601"), sizeof("1970-09-28 12:00:00") - 1,                          ngx_http_log_iso8601 },    ...};

2、vi /root/pkg/nginx-1.10.2/src/core/

static u_char            cached_http_log_iso8601[NGX_TIME_SLOTS]                                    [sizeof("1970-09-28T12:00:00+06:00")];

改为：

static u_char            cached_http_log_iso8601[NGX_TIME_SLOTS]                                    [sizeof("1970-09-28 12:00:00")];

ngx_cached_http_log_iso8601.len = sizeof("1970-09-28T12:00:00+06:00") - 1;

改为：

ngx_cached_http_log_iso8601.len = sizeof("1970-09-28 12:00:00") - 1;

p3 = &cached_http_log_iso8601[slot][0];    (void) ngx_sprintf(p3, "%4d-%02d-%02dT%02d:%02d:%02d%c%02i:%02i",                       tm.ngx_tm_year, tm.ngx_tm_mon,                       tm.ngx_tm_mday, tm.ngx_tm_hour,                       tm.ngx_tm_min, tm.ngx_tm_sec,                       tp->gmtoff < 0 ? '-' : '+',                       ngx_abs(tp->gmtoff / 60), ngx_abs(tp->gmtoff % 60));

改为：

    p3 = &cached_http_log_iso8601[slot][0];    (void) ngx_sprintf(p3, "%4d-%02d-%02d %02d:%02d:%02d%",                       tm.ngx_tm_year, tm.ngx_tm_mon,                       tm.ngx_tm_mday, tm.ngx_tm_hour,                       tm.ngx_tm_min, tm.ngx_tm_sec,                       tp->gmtoff < 0 ? '-' : '+',                       ngx_abs(tp->gmtoff / 60), ngx_abs(tp->gmtoff % 60));

./configure --user=nginx --group=nginx --prefix=/home/nginx/nginx --with-http_ssl_module --with-http_realip_module --with-http_sub_module --with-http_gzip_static_module --with-http_stub_status_module

这里只需要make，不用make install
