nginx
1：首先下载libunwind-1.1 # wget http://down.yunwei8.com/soft/linux/libunwind-1.1.tar.gz 然后安装 # tar zxvf libunwind-1.1.tar.gz # cd libunwind-1.1 # CFLAGS=-fPIC ./configure # make CFLAGS=-fPIC # make CFLAGS=-fPIC install 2：安装google-perftools： 首先下载gperftools-2.0 # wget http://down.yunwei8.com/soft/linux/gperftools-2.0.tar.gz 然后安装 # tar zxvf gperftools-2.0.tar.gz # cd gperftools-2.0/ # ./configure # make && make install # echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf # /sbin/ldconfig 3：重新编译nginx 不会安装的看这里 http://www.yunwei8.com/nginx124/ # cd /soft/nginx-1.2.4 # ./configure --user=www --group=www --prefix=/usr/local/server/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-google_perftools_module # make && make install 安装参数说明看这里：http://www.yunwei8.com/nginxcs 4：为tcmalloc添加目录，并且赋予适当权限 # mkdir -p /tmp/tcmalloc/ # chown -R www:www /tmp/tcmalloc/ 5：修改 nginx.conf ，令nginx可以 google-perftools实现加速 # vi /usr/local/server/nginx/conf/nginx.conf 修改前面几行为： user www www; worker_processes 8; error_log /web/logs/nginx_error.log crit; pid logs/nginx.pid; google_perftools_profiles /tmp/tcmalloc/; events{ use epoll; worker_connections 65535; } 6：测试和运行 # /usr/local/server/nginx/sbin/nginx -t 如果显示下面信息，即表示配置没问题 nginx: the configuration file /opt/nginx/conf/nginx.conf syntax is ok nginx: configuration file /opt/nginx/conf/nginx.conf test is successful 输入代码运行nginx服务 # /usr/local/server/nginx/sbin/nginx # ps aux|grep [n]ginx 如果显以类似下面的信息，即表示nginx已经启动 root 22900 0.0 0.1 43216 1576 ?
