准备工做:javascript
yum -y install gcc gcc-c++ autoconf automake makephp
yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel css
以后我用的阿里的那个tengine-2.1.1.tar.gz(同事给的,我就用上了,至于有什么特别之处,还待研究),html
groupadd nginx前端
useradd -g nginx nginxjava
以后编译nginx,node
tar -zxvf nginx-1.9.5.tar.gznginx
cd nginx-1.9.5c++
这个有点狠,安装了一大堆.缓存
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-mail --with-mail_ssl_module --with-pcre
make && make install
在/etc/rc.d/rc.local文件里,写上开机的脚本便可
/usr/local/nginx/sbin/nginx
调优:

open_file_cache_min_uses 1;#open_file_cache指令中的inactive参数时间内文件的最少使用次数,若是超过这个数字,文件描述符一直是在缓存中打开的,如上例,若是有一个文件在inactive时间内一次没被使用,它将被移除

接下来优化下操做系统的参数:

net.core.somaxconn=262144
net.core.netdev_max_backlog=262144
net.ipv4.tcp_max_syn_backlog=262144
fs.file-max = 6553560
net.ipv4.tcp_fin_timeout = 30
#net.ipv4.icmp_echo_ignore_all = 1 #这个是禁用被ping,防止被人ping挂了
sysctl -p #生效
