esxi服务器集群 nginx tengine 的使用

下载安装PCRE库：

PCRE库是实现Perl式正则表达式的基础。如果系统中缺少此库需要编译安装。可以从著名的开源软件网站sourceforge上下载：http://sourceforge.net/projects/pcre/files/pcre/。目前最新版本是8.20。

仍然是下载后解压、配置、编译和安装：

[root@lxp2 Downloads]# tar -xf pcre-8.20.tar.gz 

[root@lxp2 Downloads]# cd pcre-8.20[root@lxp2 pcre-8.20]# ./configure[root@lxp2 pcre-8.20]# make[root@lxp2 pcre-8.20]# sudo make install

需要调整一下系统的参数，在/etc/sysctl.conf中：

net.ipv4.ip_local_port_range = 1024 65535net.core.somaxconn = 2048  net.core.rmem_default = 262144  net.core.wmem_default = 262144  net.core.rmem_max = 16777216  net.core.wmem_max = 16777216  net.ipv4.tcp_rmem = 4096 4096 16777216  net.ipv4.tcp_wmem = 4096 4096 16777216  net.ipv4.tcp_mem = 786432 2097152 3145728  net.ipv4.tcp_max_syn_backlog = 16384  net.core.netdev_max_backlog = 20000  net.ipv4.tcp_fin_timeout = 15  net.ipv4.tcp_max_syn_backlog = 16384  net.ipv4.tcp_tw_reuse = 1  net.ipv4.tcp_tw_recycle = 1  net.ipv4.tcp_max_orphans = 131072  /sbin/sysctl -p 生效
