上传nginx-1.5.7.tar.gz到/opt/soft/
上传pcre-8.33.tar.gz到/opt/soft/
上传zlib-1.2.8.tar.gz到/opt/soft/
添加web用户
[root@localhost ~]# groupadd www
[root@localhost ~]# useradd -g www wwwweb
[root@localhost ~]# cd /opt/soft
安装rewrite组件
[root@localhost soft]# tar -zxvf pcre-8.33.tar.gz
[root@localhost soft]# cd pcre-8.33/
[root@localhost pcre-8.33]# ./configure
[root@localhost pcre-8.33]# make && make install
[root@localhost pcre-8.33]# cd ../
安装zlib组件
[root@localhost soft]# tar -zxvf zlib-1.2.8.gz
[root@localhost soft]# cd zlib-1.2.8/
[root@localhost zlib-1.2.8]# ./configure
[root@localhost zlib-1.2.8]# make && make install
[root@localhost zlib-1.2.8]# cd ../
解压安装文件
[root@localhost soft]# tar -xzvf nginx-1.5.7.tar.gz
[root@localhost soft]# cd nginx-1.5.7
编译安装文件
[root@localhost nginx-1.5.7]# ./configure --user=www --group=wwwweb --prefix=/opt/sudytech/nginx1.5.7 --with-http_stub_status_module --with-http_ssl_module
[root@localhost nginx-1.5.7]# make
[root@localhost nginx-1.5.7]# make install
启动服务
[root@localhost conf]# /usr/local/nginx/sbin/nginx
常见错误：
[root@localhost ~]# /opt/sudytech/nginx1.5.7/sbin/nginx
/opt/sudytech/nginx1.5.7/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
从错误看出是缺少lib文件导致，进一步查看下
[root@localhost ~]# ldd $(which /opt/sudytech/nginx1.5.7/sbin/nginx)
linux-gate.so.1 => (0x00200000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00ca6000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x04e3f000)
libpcre.so.1 => not found
libz.so.1 => /usr/lib/libz.so.1 (0x00ccb000)
libc.so.6 => /lib/libc.so.6 (0x00b2f000)
/lib/ld-linux.so.2 (0x00b11000)
可以看出 libpcre.so.1 => not found 并没有找到，进入/lib目录中手动链接下
[root@localhost ~]# cd /lib
[root@localhost lib]# ln -s libpcre.so.0.0.1 libpcre.so.1
然后在启动nginx ok 了
[root@localhost lib]# /usr/local/nginx/sbin/nginx
再次遇到错误
[root@localhost lib]# /opt/sudytech/nginx1.5.7/sbin/nginx
nginx: [emerg] getpwnam("www") failed
在启动nginx之前还需要添加www用户组，否则会提示
nginx: [emerg] getpwnam("www") failed
事实上我们已经添加过了
解决方案：
在nginx.conf中,在#user nobody;下添加
#启动nginx服务的用户与组
user wwwweb www;
即可
再次启动，OK~!
[root@localhost lib]# /usr/local/nginx/sbin/nginx
[root@localhost lib]# ps -ef |grep nginx
root 18889 1 0 19:01 ? 00:00:00 nginx: master process /opt/sudytech/nginx1.5.7/sbin/nginx
wwwweb 18890 18889 0 19:01 ? 00:00:00 nginx: worker process
root 18905 8704 0 19:02 pts/2 00:00:00 grep nginx
访问安装服务器ip
