Ansible自动化安装nginx

1.安装ansible

参考:运维自动化工具之Ansible

2.ansible相关配置

cat /etc/ansible/hosts[webserver]192.168.1.101192.168.1.102

3.在/etc/ansible/roles中创建nginx目录结构

[root@Centos roles]# mkdir -p/etc/ansible/roles/nginx/{defaults,files,handlers,meta,tasks,templates,vars}

整体目录结构:

install_nginx.sh内容：

#!/bin/bash#yum -y install gcc openssl-devel pcre-devel zlib-develgroupadd -r nginxuseradd -r -g nginx -s /bin/false -M nginxcd /root/soft &&tar zxf nginx-1.2.2.tar.gz && cd nginx-1.2.2 &&./configure \  --prefix=/usr/local/nginx \  --sbin-path=/usr/sbin/nginx \  --conf-path=/etc/nginx/nginx.conf \  --error-log-path=/var/log/nginx/error.log \  --http-log-path=/var/log/nginx/access.log \  --pid-path=/var/run/nginx/nginx.pid  \  --lock-path=/var/lock/nginx.lock \  --user=nginx \  --group=nginx \  --with-http_ssl_module \  --with-http_flv_module \  --with-http_stub_status_module \  --with-http_gzip_static_module \  --http-client-body-temp-path=/var/tmp/nginx/client/ \  --http-proxy-temp-path=/var/tmp/nginx/proxy/ \  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \  --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \  --http-scgi-temp-path=/var/tmp/nginx/scgi \  --with-pcremake && make install

main.yml内容:

- name: copy nginx-1.2.2.tar.gz to webservers  copy: src=nginx-1.2.2.tar.gz dest=/root/soft/nginx-1.2.2.tar.gz- name: copy install_nginx.sh to webservers  copy: src=install_nginx.sh dest=/root/soft/install_nginx.sh- name: install nginx  shell: /bin/bash /root/soft/install_nginx.sh

webservice.yml内容:

- hosts: webserver  remote_user: root  roles:  - nginx

4.执行ansible-playbook进行安装:

[root@Centos files]# cd /etc/ansible/[root@Centos ansible]# lsansible.cfg  hosts  roles  webservice.yml[root@Centos ansible]# ansible-playbook webservice.yml

安装成功!

5.测试

由于webserver两个节点安装完没有启动脚本，我们从ansible主机上拷贝一下启动脚本：

[root@Centos ansible]# scp /etc/rc.d/init.d/nginx root@192.168.1.101:/etc/rc.d/init.d/[root@Centos ansible]# scp /etc/rc.d/init.d/nginx root@192.168.1.102:/etc/rc.d/init.d/

以下为脚本内容:

#!/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  # Source function library.. /etc/rc.d/init.d/functions  # Source networking configuration.. /etc/sysconfig/network  # Check that networking is up.[ "$NETWORKING" = "no" ] && exit 0  nginx="/usr/local/nginx/sbin/nginx"prog=$(basename $nginx)  NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"  [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx  lockfile=/var/lock/subsys/nginx  make_dirs() {   # make required directories   user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`   options=`$nginx -V 2>&1 | grep 'configure arguments:'`   for opt in $options; do       if [ `echo $opt | grep '.*-temp-path'` ]; then           value=`echo $opt | cut -d "=" -f 2`           if [ ! -d "$value" ]; then               # echo "creating" $value               mkdir -p $value && chown -R $user $value           fi       fi   done}  start() {    [ -x $nginx ] || exit 5    [ -f $NGINX_CONF_FILE ] || exit 6    make_dirs    echo -n $"Starting $prog: "    daemon $nginx -c $NGINX_CONF_FILE    retval=$?    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}  restart() {    configtest || return $?    stop    sleep 1    start}  reload() {    configtest || return $?    echo -n $"Reloading $prog: "    killproc $nginx -HUP    RETVAL=$?    echo}  force_reload() {    restart}  configtest() {  $nginx -t -c $NGINX_CONF_FILE}  rh_status() {    status $prog}  rh_status_q() {    rh_status >/dev/null 2>&1}  case "$1" in    start)        rh_status_q && exit 0        $1        ;;    stop)        rh_status_q || exit 0        $1        ;;    restart|configtest)        $1        ;;    reload)        rh_status_q || exit 7        $1        ;;    force-reload)        force_reload        ;;    status)        rh_status        ;;    condrestart|try-restart)        rh_status_q || exit 0            ;;    *)        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"        exit 2esac

webserver中的两台机器启动nginx服务：

ip:192.168.1.101中--

ip:192.168.1.102中--

ok,完成!
