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));

3、修改完后重新编译

./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

mv /home/nginx/nginx/sbin/nginx /home/nginx/nginx/sbin/nginx.bak
cp objs/nginx /home/nginx/nginx/sbin/nginx
chown -R nginx: /home/nginx/nginx/sbin/
[nginx@web-nginx1 sbin]$ cd /home/nginx/nginx/sbin/ && ./nginx -t
nginx: the configuration file /home/nginx/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /home/nginx/nginx/conf/nginx.conf test is successful
kill -USR2 `cat nginx.pid` 
kill -WINCH `cat nginx.pid.oldbin`
