安裝說明
WorkerMan實際上就是一個PHP代碼包，如果你的PHP環境已經裝好，只需要把WorkerMan源代碼或者demo下載下來即可運行。

ftpLinux內核調優
為了讓系統能夠支持更大的並發，除了必須安裝event擴展(或libevent擴展)之外，優化linux內核也是重中之重，以下優化每一項都非常非常重要，請務必按逐一完成。
vim /etc/sysctl.conf
[root@workerman ~]# vim /etc/sysctl.conf
net.ipv4.tcp_max_tw_buckets = 20000
net.core.somaxconn = 65535
net.ipv4.tcp_max_syn_backlog = 262144
net.core.netdev_max_backlog = 30000
net.ipv4.tcp_tw_recycle = 0
fs.file-max = 6815744
net.netfilter.nf_conntrack_max = 2621440
設定說明
#该参数设置系统的TIME_WAIT的数量，如果超过默认值则会被立即清除
net.ipv4.tcp_max_tw_buckets = 20000
#定义了系统中每一个端口最大的监听队列的长度，这是个全局的参数
net.core.somaxconn = 65535
#对于还未获得对方确认的连接请求，可保存在队列中的最大数目
net.ipv4.tcp_max_syn_backlog = 262144
#在每个网络接口接收数据包的速率比内核处理这些包的速率快时，允许送到队列的数据包的最大数目
net.core.netdev_max_backlog = 30000
#能够更快地回收TIME-WAIT套接字。此选项会导致处于NAT网络的客户端超时，建议为0
net.ipv4.tcp_tw_recycle = 0
#系统所有进程一共可以打开的文件数量
fs.file-max = 6815744
#防火墙跟踪表的大小。注意：如果防火墙没开则会提示error: "net.netfilter.nf_conntrack_max" is an unknown key，忽略即可
net.netfilter.nf_conntrack_max = 2621440執行 sysctl -p
[root@workerman ~]# sysctl -p
net.ipv4.tcp_max_tw_buckets = 20000
net.core.somaxconn = 65535
net.ipv4.tcp_max_syn_backlog = 262144
net.core.netdev_max_backlog = 30000
net.ipv4.tcp_tw_recycle = 0
fs.file-max = 6815744
sysctl: cannot stat /proc/sys/net/netfilter/nf_conntrack_max: No such file or directory //忽略即可
打開文件數
設置系統打開文件數設置，解決高並發下too many open files問題。此選項直接影響單個進程容納的客戶端連接數。
Soft open files是Linux系統參數，影響系統單個進程能夠打開最大的文件句柄數量，這個值會影響到長連接應用如聊天中單個進程能夠維持的用戶連接數，運行ulimit -n能看到這個參數值，如果是1024，就是代表單個進程只能同時最多只能維持1024甚至更少（因為有其它文件的句柄被打開）。如果開啟4個進程維持用戶連接，那麼整個應用能夠同時維持的連接數不會超過4*1024個，也就是說最多只能支持4×1024個用戶在線可以增大這個設置以便服務能夠維持更多的TCP連接。
Soft open files 修改方法：
（1）ulimit -HSn 102400
這只是在當前終端有效，退出之後，open files 又變為默認值。
（2）在/etc/profile文件末尾添加一行ulimit -HSn 102400，這樣每次登錄終端時，都會自動執行/etc/profile。
（3）令修改open files的數值永久生效，則必須修改配置文件：/etc/security/limits.conf. 在這個文件後加上：
vim /etc/security/limits.conf
[root@workerman ~]# vim /etc/security/limits.conf
* soft nofile 1024000
* hard nofile 1024000
root soft nofile 1024000
root hard nofile 1024000
