RHEL6编译安装nginx、开机启动脚本

e13e

Nginx ("engine x") 是一个高性能的 HTTP 和 反向代理 服务器，也是一个 IMAP/POP3/SMTP 代理服务器。

nginx的模块需要第三方库的支持，检查是否安装下列库：zlib、zlib-devel（nginx扩展，gzip压缩）、openssl、openssl-devel（nginx扩展）、prce、prce-devel（重写rewrite、支持nginx伪静态）；Nginx 一般有两个版本，分别是稳定版和开发版，您可以根据您的目的来选择这两个版本的其中一个。

1、安装编译环境

1	[iyunv@localhost ~]# yum -y install gcc gcc-c++ automake autoconf libtool make

2、安装PCRE库

1 2 3 4 5

[iyunv@localhost src]# cd /usr/local/src/ [iyunv@localhost src]# wget [iyunv@localhost pcre-8.36]#  cd pcre-8.36 [iyunv@localhost pcre-8.36]# ./configure --prefix=/usr/local/pcre [iyunv@localhost pcre-8.36]# make [iyunv@localhost pcre-8.36]# make install

3、安装zlib库

1 2 3 4 5

[iyunv@localhost pcre-8.36]# cd /usr/local/src/ [iyunv@localhost src]# wget [iyunv@localhost src]# cd zlib-1.2.8 [iyunv@localhost zlib-1.2.8]# ./configure --prefix=/usr/local/zlib [iyunv@localhost zlib-1.2.8]# make [iyunv@localhost zlib-1.2.8]# make install

4、安装ssl

1 2 3 4 5 6 7

[iyunv@localhost zlib-1.2.8]# cd /usr/local/src/ [iyunv@localhost src]# wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz [iyunv@localhost src]# tar zxvf openssl-1.0.1j.tar.gz [iyunv@localhost src]# cd openssl-1.0.1j [iyunv@localhost openssl-1.0.1j]# ./config --prefix=/usr/local/openssl [iyunv@localhost openssl-1.0.1j]# make [iyunv@localhost openssl-1.0.1j]# make install

5、安装nginx

1	[iyunv@localhost openssl-1.0.1j]# cd ..

--with-openssl=/usr/local/src/openssl-1.0.1j --with-zlib=/usr/local/src/zlib-1.2.8 --with-pcre=/usr/local/src/pcre-8.36指向的是源码包解压的路径，而不是安装的路径，否则会报错

检查是否安装成功  

1 2 3 4 5

[iyunv@localhost sbin]# ./nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: [emerg] getgrnam("wwww") failed nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed [iyunv@localhost sbin]#

编译时候指定组成wwww，重新修改下即可

1 2 3 4 5 6 7 8

[iyunv@localhost nginx]# usermod -g wwww www [iyunv@localhost nginx]# id www uid=500(www) gid=501(wwww) groups=501(wwww) [iyunv@localhost nginx]# cd /usr/local/nginx/sbin/ [iyunv@localhost sbin]# ./nginx -t -c /usr/local/nginx/conf/nginx.conf nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful [iyunv@localhost sbin]#

参数"-c"指定了配置文件的路径，如果不加'-c"参数， nginx，会默认加载其安装目录中conf子目录中的nginx.conf文件。

启动nginx

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

[iyunv@localhost sbin]# ./nginx [iyunv@localhost sbin]# /usr/local/nginx/sbin/nginx nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] still could not bind() [iyunv@localhost sbin]# lsof -i :80 COMMAND     PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME clock-app  7093 root   21u  IPv4  53701      0t0  TCP 10.15.24.112:52763->63.238.2.211:http (ESTABLISHED) nginx     10145 root    6u  IPv4  53797      0t0  TCP *:http (LISTEN) nginx     10146  www    6u  IPv4  53797      0t0  TCP *:http (LISTEN) [iyunv@localhost sbin]# kill -9 7093 [iyunv@localhost sbin]# kill -9 10145 [iyunv@localhost sbin]# kill -9  10146 [iyunv@localhost sbin]# /usr/local/nginx/sbin/nginx [iyunv@localhost sbin]# netstat -ano|grep -i ":80" tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      off (0.00/0/0) [iyunv@localhost sbin]# ps -ef|grep "nginx" root     10167     1  0 05:17 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx www      10168 10167  0 05:17 ?        00:00:00 nginx: worker process       root     10174  1882  0 05:18 pts/0    00:00:00 grep nginx [iyunv@localhost sbin]#

执行/usr/local/nginx/sbin/nginx时提示端口被占用，因为前面我已经启动过了./nginx导致端口被占用，

重启nginx

1 2 3

[iyunv@localhost sbin]# /usr/local/nginx/sbin/nginx -s reload 或者 [iyunv@localhost sbin]# kill -HUP `cat /usr/local/nginx/logs/nginx.pid `

打开浏览器访问此机器的 IP，如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。

设置nginx开机启动

通过脚本来实现
