一.使用系統默認的nobody用戶管理haproxy
1>.編輯haprxoy的配置文件
[root@node102.yinzhengjie.org.cn ~]# cat /etc/haproxy/haproxy.cfg global maxconn 100000 chroot /yinzhengjie/softwares/haproxy #stats socket /var/lib/haproxy/haproxy.sock mode 600 level admin uid 99 gid 99 daemon nbproc 2 cpu-map 1 0 cpu-map 2 1 pidfile /yinzhengjie/softwares/haproxy/run/haproxy.pid log 127.0.0.1 local3 info defaults option http-keep-alive option forwardfor maxconn 100000 mode http timeout connect 300000ms timeout client 300000ms timeout server 300000ms listen stats mode http bind 0.0.0.0:9999 stats enable log global stats uri /haproxy-status stats auth haadmin:q1w2e3r4ys listen web_port bind 0.0.0.0:80 mode http log global server web1 127.0.0.1:8080 check inter 3000 fall 2 rise 5 #frontend web # bind 172.30.1.102:80 # use_backend myweb #backend myweb # server web01 172.30.1.106:80 #上面注釋的frontend和backend部分是可以通過listen指令代替 listen web bind 172.30.1.102:80 server web01 172.30.1.106:80 [root@node102.yinzhengjie.org.cn ~]#
2>.查看haprxoy運行時的用戶身份
[root@node102.yinzhengjie.org.cn ~]# id 99 uid=99(nobody) gid=99(nobody) groups=99(nobody) [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# getent passwd nobody nobody:x:99:99:Nobody:/:/sbin/nologin [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# ps -ef | grep haproxy root 20977 1 0 18:24 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid nobody 20981 20977 0 18:24 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid nobody 20982 20977 0 18:24 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid root 21144 3488 0 18:59 pts/0 00:00:00 grep --color=auto haproxy [root@node102.yinzhengjie.org.cn ~]#
二.自定義用戶管理haproxy服務
1>.創建haproxy用戶
[root@node102.yinzhengjie.org.cn ~]# useradd haproxy -r -s /sbin/nologin #創建haproxy用戶時使用"-r"參數禁止創建家目錄，使用"-s"指定該用戶我無法登錄操作系統。 [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# getent passwd haproxy haproxy:x:998:996::/home/haproxy:/sbin/nologin [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# id haproxy uid=998(haproxy) gid=996(haproxy) groups=996(haproxy) [root@node102.yinzhengjie.org.cn ~]#
2>.編輯haprxoy的配置文件
[root@node102.yinzhengjie.org.cn ~]# id haproxy uid=998(haproxy) gid=996(haproxy) groups=996(haproxy) [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# vim /etc/haproxy/haproxy.cfg [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# cat /etc/haproxy/haproxy.cfg global maxconn 100000 chroot /yinzhengjie/softwares/haproxy #stats socket /var/lib/haproxy/haproxy.sock mode 600 level admin uid 998 gid 996 daemon nbproc 2 cpu-map 1 0 cpu-map 2 1 pidfile /yinzhengjie/softwares/haproxy/run/haproxy.pid log 127.0.0.1 local3 info defaults option http-keep-alive option forwardfor maxconn 100000 mode http timeout connect 300000ms timeout client 300000ms timeout server 300000ms listen stats mode http bind 0.0.0.0:9999 stats enable log global stats uri /haproxy-status stats auth haadmin:q1w2e3r4ys listen web_port bind 0.0.0.0:80 mode http log global server web1 127.0.0.1:8080 check inter 3000 fall 2 rise 5 #frontend web # bind 172.30.1.102:80 # use_backend myweb #backend myweb # server web01 172.30.1.106:80 #上面注釋的frontend和backend部分是可以通過listen指令代替 listen web bind 172.30.1.102:80 server web01 172.30.1.106:80 [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]#
3>. 重啟haproxy服務使配置生效
[root@node102.yinzhengjie.org.cn ~]# netstat -untalp | grep haproxy tcp 0 0 0.0.0.0:9999 0.0.0.0:* LISTEN 20981/haproxy tcp 0 0 172.30.1.102:80 0.0.0.0:* LISTEN 20981/haproxy tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 20981/haproxy udp 0 0 0.0.0.0:55925 0.0.0.0:* 20977/haproxy [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# systemctl restart haproxy [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# netstat -untalp | grep haproxy tcp 0 0 0.0.0.0:9999 0.0.0.0:* LISTEN 21278/haproxy tcp 0 0 172.30.1.102:80 0.0.0.0:* LISTEN 21278/haproxy tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 21278/haproxy udp 0 0 0.0.0.0:34022 0.0.0.0:* 21274/haproxy [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]#
4>.查看haprxoy運行時的用戶身份
[root@node102.yinzhengjie.org.cn ~]# id haproxy uid=998(haproxy) gid=996(haproxy) groups=996(haproxy) [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# ps -ef | grep haproxy root 21274 1 0 19:16 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid haproxy 21278 21274 0 19:16 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid haproxy 21279 21274 0 19:16 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid root 21297 3488 0 19:17 pts/0 00:00:00 grep --color=auto haproxy [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]#
5>.修改haproxy配置文件
