一.使用系统默认的nobody用户管理haproxy
1>.编辑haprxoy的配置文件
[[email protected] ~]# 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 #上面注释的frontend和backend部分是可以通过listen指令代替 listen web bind 172.30.1.102:80 server web01 172.30.1.106:80 [[email protected] ~]#
2>.查看haprxoy运行时的用户身份
[[email protected] ~]# id 99 uid=99(nobody) gid=99(nobody) groups=99(nobody) [[email protected] ~]# [[email protected] ~]# getent passwd nobody nobody:x:99:99:Nobody:/:/sbin/nologin [[email protected] ~]# [[email protected] ~]# 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 [[email protected] ~]#
二.自定义用户管理haproxy服务
1>.创建haproxy用户
[[email protected] ~]# useradd haproxy -r -s /sbin/nologin #创建haproxy用户时使用"-r"参数禁止创建家目录，使用"-s"指定该用户我无法登录操作系统。 [[email protected] ~]# [[email protected] ~]# getent passwd haproxy haproxy:x:998:996::/home/haproxy:/sbin/nologin [[email protected] ~]# [[email protected] ~]# id haproxy uid=998(haproxy) gid=996(haproxy) groups=996(haproxy) [[email protected] ~]#
2>.编辑haprxoy的配置文件
[[email protected] ~]# id haproxy uid=998(haproxy) gid=996(haproxy) groups=996(haproxy) [[email protected] ~]# [[email protected] ~]# [[email protected] ~]# vim /etc/haproxy/haproxy.cfg [[email protected] ~]# [[email protected] ~]# 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 #上面注释的frontend和backend部分是可以通过listen指令代替 listen web bind 172.30.1.102:80 server web01 172.30.1.106:80 [[email protected] ~]# [[email protected] ~]#
3>. 重启haproxy服务使配置生效
[[email protected] ~]# 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 [[email protected] ~]# [[email protected] ~]# systemctl restart haproxy [[email protected] ~]# [[email protected] ~]# 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 [[email protected] ~]# [[email protected] ~]#
4>.查看haprxoy运行时的用户身份
[[email protected] ~]# id haproxy uid=998(haproxy) gid=996(haproxy) groups=996(haproxy) [[email protected] ~]# [[email protected] ~]# 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 [[email protected] ~]# [[email protected] ~]#
5>.修改haproxy配置文件
[[email protected] ~]# vim /etc/haproxy/haproxy.cfg [[email protected] ~]# [[email protected] ~]# getent passwd haproxy haproxy:x:998:996::/home/haproxy:/sbin/nologin [[email protected] ~]# [[email protected] ~]# 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 #也可以使用user和group指令来代替上面的uid和gid的配置 user haproxy group haproxy 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 #上面注释的frontend和backend部分是可以通过listen指令代替 listen web bind 172.30.1.102:80 server web01 172.30.1.106:80 [[email protected] ~]# [[email protected] ~]# systemctl restart haproxy [[email protected] ~]# [[email protected] ~]# ps -ef | grep haproxy root 21318 1 0 19:19 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid haproxy 21321 21318 0 19:19 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid haproxy 21322 21318 0 19:19 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid root 21324 3488 0 19:19 pts/0 00:00:00 grep --color=auto haproxy [[email protected] ~]#
