前面讲到nginx已经安装完成，接下来就是将服务启动起来。
第一种是手动启动，首先找一下nginx，找到就可以写一个命令了
#查找nginx
whereis nginx
#手动启动（启动代码格式：nginx安装目录地址 -c nginx配置文件地址）
/usr/sbin/nginx -c /etc/nginx/nginx.conf
#验证启动
http://IP第二种是服务器自动启动，首先创建一个脚本文件
vi /etc/init.d/nginx#按i进入编辑状态，复制粘贴，wq保存
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /etc/nginx/nginx.conf
# config: /etc/sysconfig/nginx
# pidfile: /var/run/nginx.pid

[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE

echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
killall -9 nginx
}
restart() {
configtest || return $?
stop
sleep 1
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo

force_reload() {

}

}

esac#赋予脚本执行权限
chmod +x /etc/init.d/nginx#添加nginx服务进程用户
groupadd -r nginx
useradd -r -g nginx nginx#添加至服务管理列表，设置开机自启
chkconfig --add nginx
chkconfig nginx on#在这里踩坑开始，出现错误“No module named 'gdbm'”或“No module named '_gdbm'”，于是离线下载了gdbm-1.12.tar.gz
下载地址找到有以下2个，都可以下载：
http://mirrors.nju.edu.cn/gnu/gdbm/
#解压
tar -zxvf gdbm-1.12.tar.gz #进入目录
cd gdbm-1.12#创建安装目录
mkdir /usr/local/gdbm-1.12#选择安装目录
./configure --enable-memory-mapped-io --prefix=/usr/local/gdbm-1.12 --enable-libgdbm-compat --enable-gdbm-export --with-gdbm183-library=/usr/lib/libgdbm.a --with-gdbm183-libdir=/usr/local/lib --with-gdbm183-includedir=/usr/local/include#编译
make#出现错误“gcc: error: /usr/lib/libgdbm.a: No such file or directory”，不管它，继续安装，装好后去“/usr/local/gdbm-1.12/lib/”目录下把的“libgdbm.a”手动复制到“/usr/lib”目录
make install
?#然后回到“gdbm-1.12”目录，清除编译缓存
make clean?#再次选择安装目录
./configure --enable-memory-mapped-io --prefix=/usr/local/gdbm-1.12 --enable-libgdbm-compat --enable-gdbm-export --with-gdbm183-library=/usr/lib/libgdbm.a --with-gdbm183-libdir=/usr/local/lib --with-gdbm183-includedir=/usr/local/include#编译
make#安装，此时gdbm已安装完成
make install#重新添加至服务管理列表，设置开机自启
chkconfig --add nginx
chkconfig nginx on#关闭防火墙
systemctl stop firewalld?#开启Nginx服务
service nginx start#验证启动成功
