nginx 配置

yum install openssl* cd /usr/local/src/ wget http://ncu.dl.sourceforge.net/project/pcre/pcre/8.32/pcre-8.32.tar.gz tar -zxf pcre-8.32.tar.gz cd pcre-8.32 ./configure --prefix=/usr/local/pcre-8.32 make && make install yum -y install gd gd2 gd-devel gd2-devel

cd /usr.local/src/

/usr/sbin/groupadd www

/usr/sbin/useradd -g www www wget http://nginx.org/download/nginx-1.7.0.tar.gz tar -zxf nginx-1.7.0.tar.gz cd nginx-1.7.0 ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.32 --with-http_realip_module --with-http_image_filter_module make && make install

启动Nginx

 

ulimit -SHn 65535

/usr/local/webserver/nginx/sbin/nginx

 

 

配置开机自动启动Nginx

 

vi /etc/rc.local 在末尾增加以下内容： ulimit -SHn 65535 /usr/local/webserver/nginx/sbin/nginx

 

优化Linux内核参数

 

vi /etc/sysctl.conf 在末尾增加以下内容: # Add net.ipv4.tcp_max_syn_backlog = 65536 net.core.netdev_max_backlog = 32768 net.core.somaxconn = 32768 net.core.wmem_default = 8388608 net.core.rmem_default = 8388608 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 2 net.ipv4.tcp_tw_recycle = 1 #net.ipv4.tcp_tw_len = 1 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_mem = 94500000 915000000 927000000 net.ipv4.tcp_max_orphans = 3276800 #net.ipv4.tcp_fin_timeout = 30 #net.ipv4.tcp_keepalive_time = 120 net.ipv4.ip_local_port_range = 1024 65535 使配置立即生效： /sbin/sysctl -p

 

添加nginx 软连接

 

ln -s /usr/local/nginx/sbin/nginx /usr/sbin/nginx nginx -t 测试配置文件 nginx -s reload 平滑重启 kill -USR2 `cat /usr/local/nginx/logs/nginx.pid` 重启 kill -INT `cat /usr/local/nginx/logs/nginx.pid` 停止
