#Linux #Nginx
一、前言
在上一篇博客中,讲述了在服务器上安装多个tomcat,现在这篇博客要讲是安装nginx
二、配置Nginx的安装环境
安装Nginx需要先将官网下载的源码进行编译,编译依赖gcc环境,如果没有gcc环境,需要安装gcc:yum install gcc-c++
,安装完gcc后,才可以进行下一步的安装
三、编译安装
-
解压缩
将Nginx安装包nginx-1.8.0.tar.gz拷贝至服务器上
解压缩安装包:
tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
-
配置安装参数
参数如下:./configure \ --prefix=/usr/local/nginx \ --pid-path=/var/run/nginx/nginx.pid \ --lock-path=/var/lock/nginx.lock \ --error-log-path=/var/log/nginx/error.log \ --http-log-path=/var/log/nginx/access.log \ --with-http_gzip_static_module \ --http-client-body-temp-path=/var/temp/nginx/client \ --http-proxy-temp-path=/var/temp/nginx/proxy \ --http-fastcgi-temp-path=/var/temp/nginx/fastcgi \ --http-uwsgi-temp-path=/var/temp/nginx/uwsgi \ --http-scgi-temp-path=/var/temp/nginx/scgi
注:上边将临时文件目录指定为/var/temp/nginx,需要在/var下创建temp及nginx目录
-
编译安装
make
make install
四、启动Nginx
cd /usr/local/nginx/sbin/
./nginx
五、停止Nginx
cd /usr/local/nginx/sbin
./nginx -s stop
此方式相当于先查出nginx进程id再使用kill命令强制杀掉进程。
方式2,完整停止(建议使用):
cd /usr/local/nginx/sbin
./nginx -s quit
此方式停止步骤是待nginx进程处理任务完毕进行停止。
六、重启Nginx
方式1,先停止再启动(建议使用):
对nginx进行重启相当于先停止nginx再启动nginx,即先执行停止命令再执行启动命令。
如下:
./nginx -s quit./nginx
方式2,重新加载配置文件:
当nginx的配置文件nginx.conf修改后,要想让配置生效需要重启nginx,使用-s reload不用先停止nginx再启动nginx即可将配置信息在nginx中生效,如下:
./nginx -s reload
七、开机自启Nginx
-
编写shell文件
vi /etc/init.d/nginx
#!/bin/bash # nginx Startup script for the Nginx HTTP Server # it is v.0.0.2 version. # chkconfig: - 85 15 # description: Nginx is a high-performance web and proxy server. # It has a lot of features, but it's not for everyone. # processname: nginx # pidfile: /var/run/nginx.pid # config: /usr/local/nginx/conf/nginx.conf nginxd=/usr/local/nginx/sbin/nginx nginx_config=/usr/local/nginx/conf/nginx.conf nginx_pid=/var/run/nginx.pid RETVAL=0 prog="nginx" # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ ${NETWORKING} = "no" ] && exit 0 [ -x $nginxd ] || exit 0 # Start nginx daemons functions. start() { if [ -e $nginx_pid ];then echo "nginx already running...." exit 1 fi echo -n $"Starting $prog: " daemon $nginxd -c ${nginx_config} RETVAL=$? echo [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx return $RETVAL } # Stop nginx daemons functions. stop() { echo -n $"Stopping $prog: " killproc $nginxd RETVAL=$? echo [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid } # reload nginx service functions. reload() { echo -n $"Reloading $prog: " #kill -HUP `cat ${nginx_pid}` killproc $nginxd -HUP RETVAL=$? echo } # See how we were called. case "$1" in start) start ;; stop) stop ;; reload) reload ;; restart) stop start ;; status) status $prog RETVAL=$? ;; *) echo $"Usage: $prog {start|stop|restart|reload|status|help}" exit 1 esac exit $RETVAL
-
设置文件访问权限
chmod a+x /etc/init.d/nginx
(a+x ==> all user can execute 所有用户可执行) -
加入到自动列表中
vi /etc/rc.local
加入一行
/etc/init.d/nginx start
保存并退出,下次重启会生效。
