12.6 Nginx安装
1. 进入下载安装包目录 ：
# cd /usr/local/src/
2. 下载nginx安装包 ：
# wget http://nginx.org/download/nginx-1.12.1.tar.gz
3. 解包解压nginx安装包 ：
# tar zxf nginx-1.12.1.tar.gz
4. 进入解压nginx包下 ：
# cd nginx-1.12.1
5. 编译nginx ：
# ./configure --prefix=/usr/local/nginx
6. make和make install ：
#make && make install
7. 在/etc/init.d/目录下,创建nginx启动脚本,并写入内容：
# vim /etc/init.d/nginx
https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/etc_init.d_nginx
写入内容如下：
#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start()
{
echo -n $"Starting $prog: "
mkdir -p /dev/shm/nginx_temp
daemon $NGINX_SBIN -c $NGINX_CONF
RETVAL=$?
echo
return $RETVAL
}
stop()
{
echo -n $"Stopping $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -TERM
rm -rf /dev/shm/nginx_temp
RETVAL=$?
echo
return $RETVAL
}
reload()
{
echo -n $"Reloading $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -HUP
RETVAL=$?
echo
return $RETVAL
}
restart()
{
stop
start
}
configtest()
{
$NGINX_SBIN -c $NGINX_CONF -t
return 0
}
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo $"Usage: $0 {start|stop|reload|restart|configtest}"
RETVAL=1
esac
exit $RETVAL
8. 给nginx(启动脚本) 设定755权限 ：
# chmod 755 /etc/init.d/nginx
9. 添加 nginx服务 到服务列表 ：
# chkconfig --add nginx
10. 设定 nginx服务 开机启动 ：
# chkconfig nginx on
11. 进入.../conf目录下 ：
# cd /usr/local/nginx/conf/
12. 先把.../conf目录下的nginx.conf文件重命名为其他名称 ：
# mv nginx.conf nginx.conf.1
13. 在.../conf目录下,创建新的nginx.conf文件,并写入内容 ：
# vim /usr/local/nginx/conf/nginx.conf
https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/nginx.conf
写入内容如下：

}
}
}
14. 检测nginx配置文件是否有错 ？
# /usr/local/nginx/sbin/nginx -t
15. 启动nginx服务 ：
# /etc/init.d/nginx start
16. 搜索nginx服务是否启动 ？
# ps aux |grep nginx
17. 创建一个1.php测试文件 ：
# vim /usr/local/nginx/html/1.php
