**1.与nginx同类的软件**

apache  
    lighttpd 
    tomcat 
    jetty 
    IIS

**2.nginx的依赖库**

gcc 
    gcc-c++
    正则库
    pcre
    pcre-devel
    
    zlib zlib-devel
    
    openssl openssl-devel

默认的安装目录

/usr/local/nginx

**修改内核参数**

/etc/sysctl.conf
    
    sysctl -p 使修改后生效

fs.file-max = 999999
    net.ipv4.tcp_tw_reuse = 1
    net.ipv4.tcp_keepalive_time = 600
    net.ipv4.tcp_fin_timeout = 30
    net.ipv4.tcp_max_tw_buckets = 5000
    net.ipv4.ip_local_port_range =1024    61000
    net.ipv4.tcp_rmem =4096 32768 262142
    net.ipv4.tcp_wmem =4096 32768 262142
    net.core.netdev_max_backlog = 8096
    net.core.rmem_default = 262144
    net.core.wmem_default = 262144
    net.core.rmem_max = 2097152
    net.core.rmem_max = 2097152
    net.ipv4.tcp_syncookies = 1
    net.ipv4.tcp_max_syn_backlog = 1024

**nginx的命令行控制**

nginx -g xx 
    nginx -g -s stop
    
    
    ➜  init-container git:(master) ✗ nginx -h
    nginx version: nginx/1.12.0
    Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives]
    
    Options:
      -?,-h         : this help
      -v            : show version and exit
      -V            : show version and configure options then exit
      -t            : test configuration and exit
      -T            : test configuration, dump it and exit
      -q            : suppress non-error messages during configuration testing
      -s signal     : send signal to a master process: stop, quit, reopen, reload
      -p prefix     : set prefix path (default: /usr/local/Cellar/nginx/1.12.0_1/)
      -c filename   : set configuration file (default: /usr/local/etc/nginx/nginx.conf)
      -g directives : set global directives out of configuration file

**nginx配置默认文件**

/usr/local/nginx

**配置的通用语法**

➜  ~ cat /usr/local/etc/nginx/nginx.conf
    
    #user nobody;
    worker_processes  1;
    
    #error_log logs/error.log;
    #error_log logs/error.log notice;
    #error_log logs/error.log info;
    
    #pid logs/nginx.pid;
