使用普通用戶啓動nginx(監牢模式)
nginx運行時，主進程一般是由root管理的
[root@web01 ~]# ps aux|grep nginx root 1340 0.0 0.8 572132 1488 ? Ss 02:41 0:00 nginx: master process /application/nginx/sbin/nginx www 1341 0.0 5.9 580624 10160 ? S 02:41 0:00 nginx: worker process www 1342 0.0 5.9 580624 10180 ? S 02:41 0:00 nginx: worker process www 1343 0.0 1.1 572132 1980 ? S 02:41 0:00 nginx: cache manager process www 1344 0.0 1.0 572132 1856 ? S 02:41 0:00 nginx: cache loader process root 1352 0.0 0.4 103332 844 pts/0 S+ 02:41 0:00 grep --color=auto nginx
部署環境
[root@web01 tools]# cat /etc/redhat-release CentOS release 6.9 (Final) [root@web01 scripts]# uname -r 2.6.32-696.el6.x86_64 [root@web01 tools]# uname -m x86_64 [root@web01 tools]# uname -a Linux moban 2.6.32-696.el6.x86_64 #1 SMP Tue Mar 21 19:29:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux [root@web01 ~]# getenforce Disabled [root@web01 ~]# /etc/init.d/iptables status iptables: Firewall is not running. [root@web01 ~]# ls /application/ nginx nginx-1.14 php php-5.5.32
在普通用戶家目錄中 創建nginx程序目錄
useradd cjh
su - cjh
mkdir -p nginx
mkdir -p nginx/{conf,html,logs}
添加生成配置文件和數據文件信息
cp /application/nginx/conf/nginx.conf ~/nginx/conf/ cp /application/nginx/conf/mime.types ~/nginx/conf/ ll ~/nginx/conf/
編寫nginx配置文件
強調說明：對於普通用戶啓動的一些網絡服務，不能使用知名端口號(1-1024)
vim ~/nginx/conf/nginx.conf
worker_processes 2;
worker_cpu_affinity 0101 1010;
worker_rlimit_nofile 65535;
error_log /home/cjh/nginx/logs/error.log;
#user cjh cjh; #普通用戶不能使用此參數配置
pid /home/cjh/nginx/logs/nginx.pid;
events {
use epoll;
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /home/cjh/nginx/logs/access.log main;
server {
listen 8080;
server_name www.123.org;
root /home/cjh/nginx/html;
index index.html index.htm;
}
}nginx -p 指定程序路徑-只有在檢查語法時可以使用
/application/nginx/sbin/nginx -t -p ~/nginx/
[cjh@web01 ~]$ /application/nginx/sbin/nginx -t -p ~/nginx/ nginx: the configuration file /home/cjh/nginx/conf/nginx.conf syntax is ok nginx: configuration file /home/cjh/nginx/conf/nginx.conf test is successful
nginx -c 指定配置文件路徑-可以指定配置文件進行(檢查語法 可以啓動nginx)
監牢模式 檢查配置文件
/application/nginx/sbin/nginx -t -p ~/nginx/
[cjh@web01 ~]$ /application/nginx/sbin/nginx -t -p ~/nginx/ nginx: the configuration file /home/cjh/nginx/conf/nginx.conf syntax is ok nginx: configuration file /home/cjh/nginx/conf/nginx.conf test is successful
/application/nginx/sbin/nginx -t -c ~/nginx/conf/nginx.conf
[cjh@web01 ~]$ /application/nginx/sbin/nginx -t -c ~/nginx/conf/nginx.conf nginx: [alert] could not open error log file: open() "/application/nginx-1.14/logs/error.log" failed (13: Permission denied) 2018/10/14 03:05:46 [warn] 1690#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /home/cjh/nginx/conf/nginx.conf:5 #注意下面兩行即可 nginx: the configuration file /home/cjh/nginx/conf/nginx.conf syntax is ok nginx: configuration file /home/cjh/nginx/conf/nginx.conf test is successful
監牢模式 啓動nginx
/application/nginx/sbin/nginx -c ~/nginx/conf/nginx.conf
[cjh@web01 ~]$ /application/nginx/sbin/nginx -c ~/nginx/conf/nginx.conf nginx: [alert] could not open error log file: open() "/application/nginx-1.14/logs/error.log" failed (13: Permission denied) 2018/10/14 03:07:18 [warn] 1709#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /home/cjh/nginx/conf/nginx.conf:5
檢查監牢模式的nginx
ps aux|grep nginx
[cjh@web01 ~]$ ps aux|grep nginx root 1340 0.0 0.9 572132 1624 ? Ss 02:41 0:00 nginx: master process /application/nginx/sbin/nginx www 1341 0.0 6.0 580624 10236 ?

創建首頁文件
echo "cjh mail [email protected]" > ~/nginx/html/index.html
