一.使用HAProxy默认的进程和线程配置
1>.编辑HAProxy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 user haproxy group haproxy daemon 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 [root@node102.yinzhengjie.org.cn ~]#
2>.启动haproxy服务
[root@node102.yinzhengjie.org.cn ~]# netstat -untalp | grep haproxy [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# systemctl start 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 12171/haproxy tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 12171/haproxy udp 0 0 0.0.0.0:43409 0.0.0.0:* 12169/haproxy [root@node102.yinzhengjie.org.cn ~]#
3>.查看haproxy的进程和线程信息
[root@node102.yinzhengjie.org.cn ~]# ps -ef | grep haproxy | grep -v grep root 12169 1 0 20:00 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid haproxy 12171 12169 0 20:00 ? 00:00:00 /usr/sbin/haproxy -Ws -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# yum -y install psmisc #安装该软件可以使用pstree命令。 [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]# pstree -p 12169 haproxy(12169)───haproxy(12171) [root@node102.yinzhengjie.org.cn ~]# [root@node102.yinzhengjie.org.cn ~]#
二.自定义进程配置
1>.编辑HAProxy的配置文件
[root@node102.yinzhengjie.org.cn ~]# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 8 On-line CPU(s) list: 0-7 Thread(s) per core: 1 Core(s) per socket: 8 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 158 Model name: Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz Stepping: 10 CPU MHz: 2207.998 BogoMIPS: 4415.99 Hypervisor vendor: KVM Virtualization type: full L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 9216K NUMA node0 CPU(s): 0-7 Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx rdtscp lm constant_tsc rep_good nopl xtopology nonstop_tsc eagerfpu pni pclmulqdq ssse3 cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt aes xsave avx rdrand hypervisor lahf_lm abm 3dnowprefetch fsgsbase avx2 invpcid rdseed clflushopt flush_l1d[root@node102.yinzhengjie.org.cn ~]#
