# :-: 安装nginx
#### 1. 安装依赖包
nginx依赖ssl,rewrite,gzip 3个包,如果没有c++编译环境需要用下面命令安装。
`yum install gcc-c++`
#### 2. 建立目录
先在home目录下建一个nginx文件夹。然后进入文件。(nginx、openssl、zlib、pcre直接下载到这个文件夹,解压也是解压到这个文件夹,都安装好后直接删除即可。)
~~~
cd home
mkdir nginx
cd nginx
~~~
#### 3. openssl库安装
ssl功能需要安装openssl库 ,官网:https://www.openssl.org。建立文件夹/alidata/library/做为这3个库的安装目录。统一放一个文件夹,日后如果想卸载,直接删除就可以。在library下面再建立openssl、zlib、pcre三个文件夹。做为那3个库的安装目录。
~~~
wget https://www.openssl.org/source/openssl-1.1.0g.tar.gz
tar -zxvf openssl-1.1.0g.tar.gz
cd openssl-1.1.0g
./config --prefix=/alidata/library/openssl && make && make install
~~~
#### 4. 安装zlib库
gzip模块需要安装zlib库,官网:http://www.zlib.net。(axel -n 后面的10是一次性建立10个连接下载)
~~~
axel -n 10 http://www.zlib.net/zlib-1.2.11.tar.gz
tar -zxvf zlib-1.2.11.tar.gz
cd zlib-1.2.11
./configure --prefix=/alidata/library/zlib && make && make install
~~~
#### 5. 安装pcre库
rewrite模块需要pcre库,官网:http://www.pcre.org。
~~~
axel -n 10 https://ftp.pcre.org/pub/pcre/pcre-8.41.tar.gz
tar -zxvf pcre-8.41.tar.gz
cd pcre-8.41
./configure --prefix=/alidata/library/pcre && make && make install
~~~
#### 6. nginx的编译安装
下载nginx,nginx的官网是http://nginx.org/。我们直接下载最新版本的nginx-1.13.7。在/alidata下建立server,然后在server下面分别建立nginx、mysql、php。后面会分别把对应的软件安装到这几个文件夹里。(--prefix:nginx的安装目录 ,--with-pcre:pcre的源码目录,--with-zlib和--with-openssl同理)
~~~
axel -n 10 http://nginx.org/download/nginx-1.13.7.tar.gz
tar -zxvf nginx-1.13.7.tar.gz
cd nginx-1.13.7
./configure \
--prefix=/alidata/server/nginx \
--with-http_realip_module \
--with-http_sub_module \
--with-http_flv_module \
--with-http_dav_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--with-http_addition_module \
--with-pcre=/home/nginx/pcre-8.41 \
--with-openssl=/home/nginx/openssl-1.1.0g \
--with-http_ssl_module \
--with-zlib=/home/nginx/zlib-1.2.11 && make && make install

#### 7. 检查nginx是否安装成功
检查nginx是否安装成功,如果出现下图信息,表示安装成功。
~~~
cd /alidata/server/nginx/sbin
./nginx -t
~~~

![](https://box.kancloud.cn/e07c544ac1f0b30823eeca19b2febc08_780x309.png)
#### 8. 常用命令
nginx的几个常用命令:
查看Nginx的版本号:./nginx -v
启动Nginx:./nginx
快速停止或关闭Nginx:./nginx -s stop
正常停止或关闭Nginx:./nginx -s quit
配置文件修改重装载命令:./nginx -s reload
#### 9. 将nginx加入系统命令
vi /etc/init.d/nginx
加入下面代码
~~~
#!/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=/alidata/server/nginx/sbin/nginx
nginx_config=/alidata/server/nginx/conf/nginx.conf
nginx_pid=/alidata/server/nginx/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 /alidata/server/nginx/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
~~~
保存上面的代码。然后添加到系统服务中。
~~~
chmod 755 /etc/init.d/nginx
chkconfig --add nginx
~~~
#### 10. 在系统服务目录中创建nginx.service文件
`vi /lib/systemd/system/nginx.service`
加入下面的代码
~~~
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
ExecStart=/alidata/server/nginx/sbin/nginx
ExecReload=/alidata/server/nginx/sbin/nginx -s reload
ExecStop=/alidata/server/nginx/sbin/nginx -s quit
PrivateTmp=true
[Install]
WantedBy=multi-user.target
~~~
保存。再执行重加载
`systemctl daemon-reload`
设置开机启动
`systemctl enable nginx.service`

#### 10. nginx服务命令
配置好之后nginx就可以用系统服务的方式操作了。
service nginx start 启动nginx
service nginx stop 关闭nginx
service nginx restart 重启nginx
service nginx reload 重新加载nginx
